Negative testing is the process of testing cases that are supposed to fail. That is, a test expects errors to happen and if the expected errors don't occur the test must fail.
 
Chainsaw supports negative testing by letting you decide what should be considered an error or not.

If for whatever reason, the kubectl get foo doesn't return an error, or the message received in standard error output is not error: the server doesn't have a resource type \"foo\", Chainsaw will consider the operation failed.

Using the match field, we can easily target failures related to specific resources.
"},{"location":"examples/non-resource-assertions/","title":"Non-resource assertions","text":"
Under certain circumstances, it makes sense to evaluate assertions that do not depend on resources. For example, when asserting the number of nodes in a cluster is equal to a known value.
 
The test below uses the x_k8s_list function to query the list of nodes in the cluster. It uses the results to compare the number of nodes found with a known number (1 in this case).

"},{"location":"examples/test-output/","title":"Test command output","text":"
Chainsaw can be used to easily check terminal output from CLIs and other commands. This is useful in that convoluted bash scripts involving chaining together tools like grep can be avoided or at least minimized to only complex use cases. Output to both stdout and stderr can be checked for a given string or precise contents.
"},{"location":"examples/test-output/#checking-output-contains","title":"Checking Output Contains","text":"
One basic use case for content checking is that the output simply contains a given string or piece of content. For example, you might want to run automated tests on a CLI binary you build to ensure that a given command produces output that contains some content you specify somewhere in the output. Let's use the following output from the kubectl version command to show these examples.
 
kubectl version\n\nClient Version: v1.28.2\nKustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3\nServer Version: v1.27.4+k3s1\n
 
Below is an example that ensures the string '1.28' is found somewhere in that output. So long as the content is present anywhere, the test will succeed. To perform this check, the contains() JMESPath filter is used.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl version\n        check:\n          # This check ensures that the string '1.28' is found\n          # in stdout or else fails\n          (contains($stdout, '1.28')): true\n
 
Checks for content containing a given value can be negated as well. For example, checking to ensure the output does NOT contain the string '1.25'.
 
- script:\n    content: kubectl version\n    check:\n      # This check ensures that the string '1.25' is NOT found\n      # in stdout or else fails\n      (contains($stdout, '1.25')): false\n
"},{"location":"examples/test-output/#checking-output-is-exactly","title":"Checking Output Is Exactly","text":"
In addition to checking that CLI/command output contains some contents, you may need to ensure that the contents are exactly as intended. The Chainsaw test below accomplishes this by comparing the entire contents of stdout with those specified in the block scalar. If so much as one character, space, or line break is off, the test will fail. This is useful in that not only can content be checked but the formatting of that content can be ensured it matches a given declaration.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl version\n        check:\n          # This check ensures the contents of stdout are exactly as shown.\n          # Any deviations will cause a failure.\n          ($stdout): |-\n            Client Version: v1.28.2\n            Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3\n            Server Version: v1.27.4+k3s1\n
"},{"location":"examples/test-output/#checking-output-in-errors","title":"Checking Output In Errors","text":"
In addition to testing that commands succeed and with output in a given shape, it's equally valuable and necessary to perform negative tests; that tests fail and with contents that are as expected. Similarly, those checks can be for output which has some contents as well as output which appears exactly as desired. For example, you may wish to check that running the kubectl foo command not only fails as expected but that the output shown to users contains a certain word or sentence.
 
kubectl foo\n\nerror: unknown command \"foo\" for \"kubectl\"\n\nDid you mean this?\n        top\n
 
Below you can see an example where the command kubectl foo is expected to fail but that the error message returned contains some output, in this case the string 'top'.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check bad kubectl command\n    try:\n    - script:\n        content: kubectl foo\n        check:\n          # This checks that the result of the content was an error.\n          ($error != null): true\n          # This check below ensures that the string 'top' is found in stderr or else fails\n          (contains($stderr, 'top')): true\n
 
Likewise, this failure output can be checked that it is precise. Note that in the example below, due to the use of a tab character in the output of kubectl foo, the value of the ($stderr) field is given as a string to preserve these non-printing characters.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl foo\n        check:\n          # This checks that the result of the content was an error.\n          ($error != null): true\n          # This checks that the output is exactly as intended.\n          ($stderr): \"error: unknown command \\\"foo\\\" for \\\"kubectl\\\"\\n\\nDid you mean this?\\n\\ttop\"\n

Another option is to use the file field. The file can be a specific file, or multiple files declared using a glob pattern:

Chainsaw makes it simple to build the documentation of your tests.
 
As test suites grow, it becomes important to document what a test does and how it is supposed to work.
 
Going through the implementation of a test to understand its purpose is not an efficient strategy.

While it is syntactically possible to create an operation with multiple actions, Chainsaw will verify and reject tests if operations containing multiple actions are found.
 
The reasoning behind this intentional choice is that it becomes harder to understand in which order actions will be executed when an operation consists of multiple actions. For this reason, operations consisting of multiple actions are not allowed.

Chainsaw is a tool primarily developed to run end-to-end tests in Kubernetes clusters.
 
It is meant to test Kubernetes operators work as expected by running a sequence of steps and asserting various conditions.
"},{"location":"quick-start/#why-we-made-it","title":"Why we made it?","text":"
While developing Kyverno we need to run end-to-end tests to make sure our admission controller works as expected.
 
A typical Kyverno end-to-end test
 
Kyverno can validate, mutate and generate resources based on policies installed in a cluster and a typical test is:
 
     
  1. Create a policy
    2.  
  2. Create a resource
    3.  
  3. Check that Kyverno acted as expected
    4.  
  4. Cleanup and move to the next test
    5.  
"},{"location":"quick-start/#how-to-use-it","title":"How to use it?","text":"
Chainsaw is built with CI tools in mind - you only really need to download and execute it in your build script.
 
However, installing it on your local machine is entirely possible.
"},{"location":"quick-start/assertion-trees/","title":"Use assertions","text":"
Chainsaw allows declaring complex assertions with a simple and no-code approach, allowing assertions based on comparisons beyond simple equality, working with arrays, and other scenarios that could not be achieved before.
 
Tip
 
Under the hood, Chainsaw uses kyverno-json assertion trees. Refer to the assertion trees documentation for more details on the supported syntax.
"},{"location":"quick-start/assertion-trees/#basic-assertion","title":"Basic assertion","text":"
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - assert:\n        resource:\n          apiVersion: apps/v1\n          kind: Deployment\n          metadata:\n            name: coredns\n            namespace: kube-system\n          spec:\n            replicas: 2\n
 
When asking Chainsaw to execute the assertion above, it will look for a deployment named coredns in the kube-system namespace and will compare the existing resource with the (partial) resource definition contained in the assertion.
 
In this specific case, if the field spec.replicas is set to 2 in the existing resource, the assertion will be considered valid. If it is not equal to 2 the assertion will be considered failed.
 
This is the most basic assertion Chainsaw can evaluate.
"},{"location":"quick-start/assertion-trees/#slightly-less-basic-assertion","title":"Slightly less basic assertion","text":"
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - assert:\n        resource:\n          apiVersion: apps/v1\n          kind: Deployment\n          metadata:\n            labels:\n              k8s-app: kube-dns\n            namespace: kube-system\n          spec:\n            replicas: 2\n
 
This time we are not providing a resource name.
 
Chainsaw will look up all deployments with the k8s-app: kube-dns label in the kube-system namespace. The assertion will be considered valid if at least one deployment matches the (partial) resource definition contained in the assertion. If none match, the assertion will be considered failed.
 
Apart from the resource lookup process being a little bit more interesting, this kind of assertion is essentially the same as the previous one. Chainsaw is basically making a decision by comparing an actual and expected resource.
"},{"location":"quick-start/assertion-trees/#beyond-simple-equality","title":"Beyond simple equality","text":"
The assertion below will check that the number of replicas for a deployment is greater than 1 AND less than 4.
 
Chainsaw doesn't need to know the exact expected number of replicas. The (replicas > 1 && replicas < 4) expression will be evaluated until the result is true or the operation timeout expires (making the assertion fail).

This assertion uses the ~ modifier and Chainsaw will evaluate descendants once per element in the array.
"},{"location":"quick-start/assertion-trees/#comprehensive-reporting","title":"Comprehensive reporting","text":"
Chainsaw offers detailed resource diffs upon assertion failures.
 
In the example below, the assertion failure message (metadata.annotations.foo: Invalid value: \"null\": Expected value: \"bar\") is augmented with a resource diff.
 
It provides a clear view of discrepancies between expected and actual resources and gives more context around the specific failure (we can easily identify the owner of the offending pod for example).

To continue our exploration of the main Chainsaw features, let's look at bindings and resource templating next.
"},{"location":"quick-start/bindings/","title":"Use bindings","text":"
You can think of bindings as a side context where you can store and retrieve data based on keys.
 
This is particularly useful when some data is only known at runtime. For example, to pass data from one operation to another, to implement resource templating, to fetch data from an external system, etc.
 
Chainsaw offers some built-in bindings you can directly use in your tests but you can also create your own bindings if needed.
"},{"location":"quick-start/bindings/#inheritance","title":"Inheritance","text":"
Bindings can be configured at the test, step or operation level.
 
All bindings configured at a given level are automatically inherited in child levels.
 
JMESPath
 
Chainsaw uses the JMESPath language, and bindings are implemented using lexical scoping.
"},{"location":"quick-start/bindings/#immutability","title":"Immutability","text":"
Bindings are immutable. This means two bindings can have the same name without overwriting each other.
 
When a binding is registered it potentially hides other bindings with the same name.
 
When this binding goes out of scope, previously registered bindings with the same name become visible again.
"},{"location":"quick-start/bindings/#built-in-bindings","title":"Built-in bindings","text":"
The $namespace binding is a good example of a built-in binding provided by Chainsaw. It contains the name of the ephemeral namespace used to execute a test (by default Chainsaw will create an ephemeral namespace for each test).
 
In the operation below, we are assigning the value of the $namespace binding to an environment variable, and echo it in a script:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - script:\n        env:\n          # assign the value of the `$namespace` binding\n          # to the environment variable `FOO`\n        - name: FOO\n          value: ($namespace)\n        content: echo $FOO\n
"},{"location":"quick-start/bindings/#custom-bindings","title":"Custom bindings","text":"
On top of built-in bindings, you can also create your own ones, combine bindings together, call JMESPath functions using bindings as arguments, etc.
 
In the test below we create custom bindings at different levels in the test, combine them by calling the join function, assign the result to an environment variable, and echo it in a script:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  # bindings can be declared at the test level\n  bindings:\n  - name: chainsaw\n    value: chainsaw\n  steps:\n    # bindings can also be declared at the step level\n  - bindings:\n    - name: hello\n      value: hello\n    try:\n    - script:\n        # bindings can also be declared at the operation level\n        bindings:\n        - name: awesome\n          value: awesome\n        env:\n          # combined bindings together using the `join` functions and\n          # assign the result to the GREETINGS environment variable\n        - name: GREETINGS\n          value: (join(' ', [$hello, $chainsaw, 'is', $awesome]))\n        content: echo $GREETINGS\n
"},{"location":"quick-start/bindings/#next-step","title":"Next step","text":"
Let's see how bindings can be useful with resource templating.
"},{"location":"quick-start/cleanup/","title":"Control your cleanup","text":"
Unless configured differently, by default Chainsaw will automatically remove the resources it created after a test finishes.
 
Cleanup happens in reverse order of creation (created last, cleaned up first). This is important, especially when the controller being tested makes use of finalizers.
 
Overriding cleanup timeout
 
Note that Chainsaw performs a blocking deletion, that is, it will wait until the resource is not present anymore in the cluster before proceeding with the next resource cleanup.
"},{"location":"quick-start/cleanup/#timeout","title":"Timeout","text":"
A global cleanup timeout can be defined at the configuration level or using command line flags.
 
It can also be overridden on a per-test or per-step basis but not at the operation level.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  timeouts:\n    # cleanup timeout at the test level\n    cleanup: 30s\n  steps:\n  - timeouts:\n      # cleanup timeout at the step level\n      cleanup: 2m\n    try: ...\n
"},{"location":"quick-start/cleanup/#automatic-cleanup","title":"Automatic cleanup","text":"
After a test, every resource created by Chainsaw will be automatically deleted. This applies to create and apply operations.
 
In the logs below we can see Chainsaw deletes the previously created resource:

"},{"location":"quick-start/cleanup/#manual-cleanup","title":"Manual cleanup","text":"
Under certain circumstances, automatic cleanup is not enough and we want to execute custom operations.
 
Chainsaw allows registering cleanup operations that will be run after automatic cleanup. Custom cleanup operations live at the test step level:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n    # this step will create a local cluster\n  - try:\n    - script:\n        timeout: 1m\n        content: |\n          kind create cluster --name dynamic --kubeconfig ./dynamic\n    # at cleanup time, we want to delete the local cluster we created\n    # and remove the associated kubeconfig\n    cleanup:\n    - script:\n        content: |\n          kind delete cluster --name dynamic\n    - script:\n        content: |\n          rm -f ./dynamic\n

"},{"location":"quick-start/first-test/","title":"Create a test","text":"
To create a Chainsaw test all you need to do is to create one (or more) YAML file(s).
 
The recommended approach is to create one folder per test, with a chainsaw-test.yaml file containing one (or more) test definition(s). The test definition can reference other files in the same folder or anywhere else on the file system as needed.
 
Tip
 
While chainsaw supports other syntaxes, we strongly recommend the explicit approach.
"},{"location":"quick-start/first-test/#what-is-a-test","title":"What is a test?","text":"
To put it simply, a test can be represented as an ordered sequence of test steps.
 
In turn, a test step can be represented as an ordered sequence of operations.

Tip
 
Chainsaw expects a path to the test folder and will discover tests by analyzing files recursively. When no path is provided Chainsaw will use the current path by default (.).
"},{"location":"quick-start/run-tests/#next-step","title":"Next step","text":"
The test above demonstrates the most basic usage of Chainsaw. In the next sections, we will look at the main features that make Chainsaw a very unique tool.
"},{"location":"quick-start/timeouts/","title":"Control your timeouts","text":"
Timeouts in Chainsaw are specified per type of operation. This is handy because the timeout varies greatly depending on the nature of an operation.
 
For example, applying a manifest in a cluster is expected to be reasonably fast, while validating a resource can be a long operation.
"},{"location":"quick-start/timeouts/#inheritance","title":"Inheritance","text":"
Timeouts can be configured globally and at the test, step or individual operation level.
 
All timeouts configured at a given level are automatically inherited in child levels. When looking up a timeout, the most specific one takes precedence over the others.
 
Info
 
To learn more about timeouts and how to configure global values, see the timeouts configuration page.

"},{"location":"quick-start/timeouts/#next-step","title":"Next step","text":"
In the next section, we will see how Chainsaw manages cleanup.
"},{"location":"quick-start/try-catch/","title":"Use try, catch and finally","text":"
A test step is made of 3 main blocks used to determine the actions Chainsaw will perform when executing the step, depending on operations outcome.
 
     
  • The try block (required)
    •  
  • The catch block (optional)
    •  
  • The finally block (optional)
    •  
 
Operations defined in the try block are executed first, then:
 
     
  • If an operation fails to execute, Chainsaw won't execute the remaining operations and will execute all operations defined in the catch block instead (if any).
    •  
  • If all operations succeed, Chainsaw will NOT execute operations defined in the catch block (if any).
    •  
  • Regardless of the step outcome (success or failure), Chainsaw will execute all operations defined in the finally block (if any).
    •  
 
Note
 
Note that all operations coming from the catch or finally blocks are executed. If one operation fails, Chainsaw will mark the test as failed and continue executing with the next operation.
"},{"location":"quick-start/try-catch/#cleanup","title":"Cleanup","text":"
At the end of a test, Chainsaw automatically cleans up the resources created during the test (cleanup is done in the opposite order of creation).
 
All operations from the catch and finally blocks are executed before the cleanup process kicks in. This order allows analyzing the resources that potentially caused the step failure before they are deleted.
"},{"location":"quick-start/try-catch/#catch","title":"Catch","text":"
Operations in a catch block are executed only when the step is considered failed.
 
This is particularly useful to collect additional information to help understand what caused the failure.
 
In the example below, the test contains a catch block to collect events in the cluster when an operation fails in the step.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # ...\n    - assert:\n        # ...\n    # collect events in the `catch` block\n    # will be executed only if an operation failed\n    catch:\n    - events: {}\n
"},{"location":"quick-start/try-catch/#finally","title":"Finally","text":"
Operations in a finally block will always execute regardless of the success or failure of the test step.
 
This is particularly useful to perform manual cleanup.
 
In the example below we create a local cluster in a script operation. The cluster deletion script is added to the finally block, guaranteeing the cluster will be deleted regardless of the test outcome.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n    # create a local cluster\n  - try:\n    - script:\n        timeout: 1m\n        content: |\n          kind create cluster --name dynamic --kubeconfig ./dynamic\n    - apply:\n        # ...\n    - assert:\n        # ...\n    # add cluster deletion script in the `finally` block\n    # to guarantee the cluster will be deleted after the test\n    finally:\n    - script:\n        content: |\n          kind delete cluster --name dynamic\n    - script:\n        content: |\n          rm -f ./dynamic\n

Under certain circumstances, it can be useful to configure catch blocks at a higher level than the step grain. At the test or configuration level.
 
This allows for declaring common catch statements we want to execute when an error occurs. Those catch blocks are combined to produce the final catch block in the following order:
 
     
  1. catch statements from the configuration level are executed first (if any)
    2.

Warning
 
While Chainsaw supports the conventional approach, we strongly recommend the explicit one.
 
If you are new to Chainsaw we suggest you skip this section and jump directly to the Explicit approach.
"},{"location":"test/conventional/#introduction","title":"Introduction","text":"
The conventional approach is the simplest and less verbose one.
 
You provide bare Kubernetes resource manifests and Chainsaw will use those manifests to create, update, or assert expectations against a cluster.
"},{"location":"test/conventional/#limitations","title":"Limitations","text":"
While this syntax is simple, it suffers lots of limitations. It doesn't support deletion operations, commands, scripts, and all Chainsaw helpers.
 
It is also impossible to specify additional configuration per test, step or individual operation (timeouts, additional verifications, etc...), making this approach highly limited.
 
It also relies a lot on file naming conventions which can be error prone.
 
Finally, this approach doesn't encourage reusing files across tests and leads to duplication, making maintenance harder.
"},{"location":"test/conventional/#file-naming-convention","title":"File naming convention","text":"
Manifest files must follow a specific naming convention: 
<step index>-<name|assert|errors>.yaml\n
 
As an example, 00-configmap.yaml, 01-assert.yaml and 02-errors.yaml are valid file names.
"},{"location":"test/conventional/#assembling-steps","title":"Assembling steps","text":"
It's perfectly valid to have multiple files for the same step.
 
Let's say we have the following files 00-resources.yaml, 00-more-resources.yaml, 00-assert.yaml and 00-errors.yaml:
 
     
  • 00-resources.yaml and 00-more-resources.yaml contain resources that will be applied in step 00
    •  
  • 00-assert.yaml contains assert statements in step 00
    •  
  • 00-errors.yaml contains error statements in step 00
    •  
 
With the four files above, Chainsaw will assemble a test step made of the combination of all those files.
"},{"location":"test/conventional/#loading-process","title":"Loading process","text":"
The logic to determine the content of a step is always:
 
     
  • The step index is obtained from the beginning of the file name, it must be composed of two numbers between 0 and 9 (from 00 to 99)
    •  
  • The next character acts as a separator and is expected to be -
    •  
  • The rest of the file name (without extension) is then evaluated
       
    • If it is equal to assert, the content is considered assertion statements
      •  
    • If it is equal to error, the content is considered error statements
      •  
    • Else the content is considered resources to be applied

At the end of the test, Chainsaw cleans up resources it created during the test, in the opposite order of creation.
 
By default, when a step fails, Chainsaw stops the execution and the remaining steps are not executed. The cleanup process starts at the moment the test stops executing.
 
Tip
 
Note that when a failure happens during cleanup, the test is marked as failed and Chainsaw continues executing cleanup for the remaining steps.

Chainsaw prioritizes its configuration in the following order:

    2.

    If no configuration is specified, Chainsaw will look for a default file named .chainsaw.yaml in the current working directory
     
    3.  
  3.  
    Internal default configuration
     
    In the absence of both of the above, Chainsaw will use a default configuration file embedded in the Chainsaw binary

Negative testing is the process of testing cases that are supposed to fail. That is, a test expects errors to happen and if the expected errors don't occur the test must fail.
 
Chainsaw supports negative testing by letting you decide what should be considered an error or not.
 
Tip
 
By default, Chainsaw will consider an operation failed if there was an error executing it (non-zero exit code in scripts and commands, error returned by the API server when calling into Kubernetes, etc...).

Chainsaw can be used to easily check terminal output from CLIs and other commands. This is useful in that convoluted bash scripts involving chaining together tools like grep can be avoided or at least minimized to only complex use cases. Output to both stdout and stderr can be checked for a given string or precise contents.
"},{"location":"examples/test-output/#checking-output-contains","title":"Checking Output Contains","text":"
One basic use case for content checking is that the output simply contains a given string or piece of content. For example, you might want to run automated tests on a CLI binary you build to ensure that a given command produces output that contains some content you specify somewhere in the output. Let's use the following output from the kubectl version command to show these examples.
 
kubectl version\n\nClient Version: v1.28.2\nKustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3\nServer Version: v1.27.4+k3s1\n
 
Below is an example that ensures the string '1.28' is found somewhere in that output. So long as the content is present anywhere, the test will succeed. To perform this check, the contains() JMESPath filter is used.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl version\n        check:\n          # This check ensures that the string '1.28' is found\n          # in stdout or else fails\n          (contains($stdout, '1.28')): true\n
 
Checks for content containing a given value can be negated as well. For example, checking to ensure the output does NOT contain the string '1.25'.
 
- script:\n    content: kubectl version\n    check:\n      # This check ensures that the string '1.25' is NOT found\n      # in stdout or else fails\n      (contains($stdout, '1.25')): false\n
"},{"location":"examples/test-output/#checking-output-is-exactly","title":"Checking Output Is Exactly","text":"
In addition to checking that CLI/command output contains some contents, you may need to ensure that the contents are exactly as intended. The Chainsaw test below accomplishes this by comparing the entire contents of stdout with those specified in the block scalar. If so much as one character, space, or line break is off, the test will fail. This is useful in that not only can content be checked but the formatting of that content can be ensured it matches a given declaration.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl version\n        check:\n          # This check ensures the contents of stdout are exactly as shown.\n          # Any deviations will cause a failure.\n          ($stdout): |-\n            Client Version: v1.28.2\n            Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3\n            Server Version: v1.27.4+k3s1\n
"},{"location":"examples/test-output/#checking-output-in-errors","title":"Checking Output In Errors","text":"
In addition to testing that commands succeed and with output in a given shape, it's equally valuable and necessary to perform negative tests; that tests fail and with contents that are as expected. Similarly, those checks can be for output which has some contents as well as output which appears exactly as desired. For example, you may wish to check that running the kubectl foo command not only fails as expected but that the output shown to users contains a certain word or sentence.
 
kubectl foo\n\nerror: unknown command \"foo\" for \"kubectl\"\n\nDid you mean this?\n        top\n
 
Below you can see an example where the command kubectl foo is expected to fail but that the error message returned contains some output, in this case the string 'top'.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check bad kubectl command\n    try:\n    - script:\n        content: kubectl foo\n        check:\n          # This checks that the result of the content was an error.\n          ($error != null): true\n          # This check below ensures that the string 'top' is found in stderr or else fails\n          (contains($stderr, 'top')): true\n
 
Likewise, this failure output can be checked that it is precise. Note that in the example below, due to the use of a tab character in the output of kubectl foo, the value of the ($stderr) field is given as a string to preserve these non-printing characters.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: test\nspec:\n  steps:\n  - name: Check kubectl\n    try:\n    - script:\n        content: kubectl foo\n        check:\n          # This checks that the result of the content was an error.\n          ($error != null): true\n          # This checks that the output is exactly as intended.\n          ($stderr): \"error: unknown command \\\"foo\\\" for \\\"kubectl\\\"\\n\\nDid you mean this?\\n\\ttop\"\n

"},{"location":"general/checks/","title":"Operation checks","text":"
Considering an operation's success or failure is not always as simple as checking an error code.
 
     
  • Sometimes an operation can fail but the failure is what you expected, hence the operation should be reported as successful.
    •  
  • Sometimes an operation can succeed but the result is not what you expected, in this case, the operation should be reported as a failure.
    •  
 
To support those kinds of use cases, some operations support additional checks to evaluate the operation result against an assertion tree.
"},{"location":"general/checks/#input-model","title":"Input model","text":"
Different operations have a different model passed through the assertion tree.
 
Please consult the Built-in bindings reference documentation to learn what is available depending on the operation.
"},{"location":"general/checks/#expect-vs-check","title":"Expect vs Check","text":"
While a simple check is enough to determine the result of a single operation, we needed a more advanced construct to cover apply, create, delete, patch and update operations. Those operations can operate on files containing multiple resources and every resource can lead to a different result and expectation.
"},{"location":"general/checks/#check","title":"Check","text":"
The example below uses a simple check. The operation is expected to fail (($error != null): true):
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - script:\n        content: |\n          exit 1\n        check:\n          # an error is expected, this will:\n          # - succeed if the operation failed\n          # - fail if the operation succeeded\n          ($error != null): true\n
"},{"location":"general/checks/#expect","title":"Expect","text":"
To support more granular checks we use the expect field that contains an array of Expectations.
 
Every expectation is made of an optional match combined with a check statement.
 
This way it is possible to control the scope of a check:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - create:\n        file: resources.yaml\n        expect:\n        - match:\n            # this check applies only if the match\n            # statement below evaluates to `true`\n            apiVersion: v1\n            kind: ConfigMap\n          check:\n            # an error is expected, this will:\n            # - succeed if the operation failed\n            # - fail if the operation succeeded\n            ($error != null): true\n
 
In the test above, only config maps are expected to fail. If the resources.yaml file contains other type of resources they are supposed to be created without error (if an error happens for a non config map resource, the operation will be considered a failure).
"},{"location":"general/inheritance/","title":"Inheritance","text":"

Chainsaw tests often need to reference resources. Including references in tests can be done in multiple ways.
"},{"location":"general/references/#inline","title":"Inline","text":"
One way to declare a resource is to do it directly inside the test definition:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # specify resource inline\n        resource:\n          apiVersion: v1\n          kind: ConfigMap\n          metadata:\n            name: quick-start\n          data:\n            foo: bar\n
 
This doesn't encourage file reuse but can be handy, especially when the resource definition is short or when the execution environment doesn't support file system access.
"},{"location":"general/references/#file-reference","title":"File reference","text":"
Another option is to use the file field. The file can be a specific file, or multiple files declared using a glob pattern:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # use a specific file\n        file: my-configmap.yaml\n---\napiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # use glob pattern\n        file: \"configs/*.yaml\"\n
"},{"location":"general/references/#url-reference","title":"URL reference","text":"
A third option is to use a URL. Chainsaw uses https://github.com/hashicorp/go-getter, it will download the content from the remote service and load it in the operation resources:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # use an URL\n        file: https://raw.githubusercontent.com/kyverno/chainsaw/main/testdata/step/configmap.yaml\n
"},{"location":"general/references/#cardinality","title":"Cardinality","text":"
When using file-based references, it is important to note that the referenced file(s) can declare multiple resources. Internally, Chainsaw will duplicate the operation once per resource.
 
This is important to keep this in mind, especially when working with bindings and outputs. Bindings and outputs will be evaluated for every operation instance.
"},{"location":"general/templating/","title":"Templating","text":"
Chainsaw simplifies dynamic configuration with native templating support.
 
In the past, users have created all sorts of hacks using tools like envsubst for dynamic substitution of env-variables. Those workarounds usually lack flexibility and introduce new problems like hiding the real resources from Chainsaw, preventing it from cleaning resources properly.
 
Templating in Chainsaw solves exactly this kind of problem.

Tip
 
Resource templating is heavily based on bindings and uses JMESPath language.

Chainsaw is a tool primarily developed to run end-to-end tests in Kubernetes clusters.

While developing Kyverno we need to run end-to-end tests to make sure our admission controller works as expected.
 
A typical Kyverno end-to-end test
 
Kyverno can validate, mutate and generate resources based on policies installed in a cluster and a typical test is:
 
     
  1. Create a policy
    2.  
  2. Create a resource
    3.  
  3. Check that Kyverno acted as expected
    4.  
  4. Cleanup and move to the next test
    5.

Chainsaw is built with CI tools in mind - you only really need to download and execute it in your build script.
 
However, installing it on your local machine is entirely possible.
"},{"location":"quick-start/assertion-trees/","title":"Use assertions","text":"
Chainsaw allows declaring complex assertions with a simple and no-code approach, allowing assertions based on comparisons beyond simple equality, working with arrays, and other scenarios that could not be achieved before.
 
Tip
 
Under the hood, Chainsaw uses kyverno-json assertion trees. Refer to the assertion trees documentation for more details on the supported syntax.
"},{"location":"quick-start/assertion-trees/#basic-assertion","title":"Basic assertion","text":"
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - assert:\n        resource:\n          apiVersion: apps/v1\n          kind: Deployment\n          metadata:\n            name: coredns\n            namespace: kube-system\n          spec:\n            replicas: 2\n
 
When asking Chainsaw to execute the assertion above, it will look for a deployment named coredns in the kube-system namespace and will compare the existing resource with the (partial) resource definition contained in the assertion.
 
In this specific case, if the field spec.replicas is set to 2 in the existing resource, the assertion will be considered valid. If it is not equal to 2 the assertion will be considered failed.
 
This is the most basic assertion Chainsaw can evaluate.
"},{"location":"quick-start/assertion-trees/#slightly-less-basic-assertion","title":"Slightly less basic assertion","text":"

This time we are not providing a resource name.
 
Chainsaw will look up all deployments with the k8s-app: kube-dns label in the kube-system namespace. The assertion will be considered valid if at least one deployment matches the (partial) resource definition contained in the assertion. If none match, the assertion will be considered failed.
 
Apart from the resource lookup process being a little bit more interesting, this kind of assertion is essentially the same as the previous one. Chainsaw is basically making a decision by comparing an actual and expected resource.
"},{"location":"quick-start/assertion-trees/#beyond-simple-equality","title":"Beyond simple equality","text":"
The assertion below will check that the number of replicas for a deployment is greater than 1 AND less than 4.
 
Chainsaw doesn't need to know the exact expected number of replicas. The (replicas > 1 && replicas < 4) expression will be evaluated until the result is true or the operation timeout expires (making the assertion fail).

Tip
 
To indicate that a key or value in the YAML document is an expression, simply place the element between parentheses:
 
     
  • this is an expression -> interpreted as a string

To continue our exploration of the main Chainsaw features, let's look at bindings and resource templating next.
"},{"location":"quick-start/bindings/","title":"Use bindings","text":"
You can think of bindings as a side context where you can store and retrieve data based on keys.
 
This is particularly useful when some data is only known at runtime. For example, to pass data from one operation to another, to implement resource templating, to fetch data from an external system, etc.
 
Chainsaw offers some built-in bindings you can directly use in your tests but you can also create your own bindings if needed.
"},{"location":"quick-start/bindings/#inheritance","title":"Inheritance","text":"
Bindings can be configured at the test, step or operation level.
 
All bindings configured at a given level are automatically inherited in child levels.
 
JMESPath
 
Chainsaw uses the JMESPath language, and bindings are implemented using lexical scoping.
"},{"location":"quick-start/bindings/#immutability","title":"Immutability","text":"
Bindings are immutable. This means two bindings can have the same name without overwriting each other.
 
When a binding is registered it potentially hides other bindings with the same name.
 
When this binding goes out of scope, previously registered bindings with the same name become visible again.
"},{"location":"quick-start/bindings/#built-in-bindings","title":"Built-in bindings","text":"
The $namespace binding is a good example of a built-in binding provided by Chainsaw. It contains the name of the ephemeral namespace used to execute a test (by default Chainsaw will create an ephemeral namespace for each test).
 
In the operation below, we are assigning the value of the $namespace binding to an environment variable, and echo it in a script:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - script:\n        env:\n          # assign the value of the `$namespace` binding\n          # to the environment variable `FOO`\n        - name: FOO\n          value: ($namespace)\n        content: echo $FOO\n
"},{"location":"quick-start/bindings/#custom-bindings","title":"Custom bindings","text":"
On top of built-in bindings, you can also create your own ones, combine bindings together, call JMESPath functions using bindings as arguments, etc.
 
In the test below we create custom bindings at different levels in the test, combine them by calling the join function, assign the result to an environment variable, and echo it in a script:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  # bindings can be declared at the test level\n  bindings:\n  - name: chainsaw\n    value: chainsaw\n  steps:\n    # bindings can also be declared at the step level\n  - bindings:\n    - name: hello\n      value: hello\n    try:\n    - script:\n        # bindings can also be declared at the operation level\n        bindings:\n        - name: awesome\n          value: awesome\n        env:\n          # combined bindings together using the `join` functions and\n          # assign the result to the GREETINGS environment variable\n        - name: GREETINGS\n          value: (join(' ', [$hello, $chainsaw, 'is', $awesome]))\n        content: echo $GREETINGS\n

Let's see how bindings can be useful with resource templating.
"},{"location":"quick-start/cleanup/","title":"Control your cleanup","text":"
Unless configured differently, by default Chainsaw will automatically remove the resources it created after a test finishes.
 
Cleanup happens in reverse order of creation (created last, cleaned up first). This is important, especially when the controller being tested makes use of finalizers.
 
Overriding cleanup timeout
 
Note that Chainsaw performs a blocking deletion, that is, it will wait until the resource is not present anymore in the cluster before proceeding with the next resource cleanup.
"},{"location":"quick-start/cleanup/#timeout","title":"Timeout","text":"
A global cleanup timeout can be defined at the configuration level or using command line flags.
 
It can also be overridden on a per-test or per-step basis but not at the operation level.

Under certain circumstances, automatic cleanup is not enough and we want to execute custom operations.
 
Chainsaw allows registering cleanup operations that will be run after automatic cleanup. Custom cleanup operations live at the test step level:
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n    # this step will create a local cluster\n  - try:\n    - script:\n        timeout: 1m\n        content: |\n          kind create cluster --name dynamic --kubeconfig ./dynamic\n    # at cleanup time, we want to delete the local cluster we created\n    # and remove the associated kubeconfig\n    cleanup:\n    - script:\n        content: |\n          kind delete cluster --name dynamic\n    - script:\n        content: |\n          rm -f ./dynamic\n

"},{"location":"quick-start/first-test/","title":"Create a test","text":"
To create a Chainsaw test all you need to do is to create one (or more) YAML file(s).
 
The recommended approach is to create one folder per test, with a chainsaw-test.yaml file containing one (or more) test definition(s). The test definition can reference other files in the same folder or anywhere else on the file system as needed.
 
Tip
 
While chainsaw supports other syntaxes, we strongly recommend the explicit approach.
"},{"location":"quick-start/first-test/#what-is-a-test","title":"What is a test?","text":"
To put it simply, a test can be represented as an ordered sequence of test steps.
 
In turn, a test step can be represented as an ordered sequence of operations.
 
When one of the operations fails the test is considered failed.
 
If all operations succeed the test is considered successful.

  1. Create a ConfigMap from a manifest
    2.  
  2. Verify the ConfigMap was created and contains the expected data
    3.  
 
Follow the instructions below to create the folder and files defining our first test.

Operation outputs can be useful for communicating and reusing computation results across operations.

Once an output has been added to the bindings context, this binding will be available to all following operations in the same step.
 
Currently, outputs do not cross the step boundaries.
"},{"location":"quick-start/operation-outputs/#matching","title":"Matching","text":"
An output supports an optional match field. The match is used to conditionally create a binding.
 
In the case of applying a file, for example, the file may contain multiple resources. The match can be used to select the resource to use for creating the binding.

The example below invokes a kubectl command to get a configmap from the cluster in json format.
 
The json output is then parsed and added to the $cm binding and the next operation performs an assertion on it by reading the binding instead of querying the cluster.

Chainsaw simplifies dynamic resource configuration with native resource templating support.
 
Sometimes things we need to create resources or assertions are only known at runtime.
 
In the past, users have created all sorts of hacks using tools like envsubst for dynamic substitution of env-variables. Those workarounds usually lack flexibility and introduce new problems like hiding the real resources from Chainsaw, preventing it from cleaning resources properly.
 
Tip
 
Resource templating is heavily based on bindings and uses JMESPath language.

Timeouts in Chainsaw are specified per type of operation. This is handy because the timeout varies greatly depending on the nature of an operation.

In the next section, we will see how Chainsaw manages cleanup.
"},{"location":"quick-start/try-catch/","title":"Use try, catch and finally","text":"
A test step is made of 3 main blocks used to determine the actions Chainsaw will perform when executing the step, depending on operations outcome.
 
     
  • The try block (required)
    •  
  • The catch block (optional)
    •  
  • The finally block (optional)
    •  
 
Operations defined in the try block are executed first, then:
 
     
  • If an operation fails to execute, Chainsaw won't execute the remaining operations and will execute all operations defined in the catch block instead (if any).
    •  
  • If all operations succeed, Chainsaw will NOT execute operations defined in the catch block (if any).
    •  
  • Regardless of the step outcome (success or failure), Chainsaw will execute all operations defined in the finally block (if any).
    •  
 
Note
 
Note that all operations coming from the catch or finally blocks are executed. If one operation fails, Chainsaw will mark the test as failed and continue executing with the next operation.
"},{"location":"quick-start/try-catch/#cleanup","title":"Cleanup","text":"
At the end of a test, Chainsaw automatically cleans up the resources created during the test (cleanup is done in the opposite order of creation).
 
All operations from the catch and finally blocks are executed before the cleanup process kicks in. This order allows analyzing the resources that potentially caused the step failure before they are deleted.
"},{"location":"quick-start/try-catch/#catch","title":"Catch","text":"
Operations in a catch block are executed only when the step is considered failed.
 
This is particularly useful to collect additional information to help understand what caused the failure.
 
In the example below, the test contains a catch block to collect events in the cluster when an operation fails in the step.
 
apiVersion: chainsaw.kyverno.io/v1alpha1\nkind: Test\nmetadata:\n  name: example\nspec:\n  steps:\n  - try:\n    - apply:\n        # ...\n    - assert:\n        # ...\n    # collect events in the `catch` block\n    # will be executed only if an operation failed\n    catch:\n    - events: {}\n
"},{"location":"quick-start/try-catch/#finally","title":"Finally","text":"
Operations in a finally block will always execute regardless of the success or failure of the test step.
 
This is particularly useful to perform manual cleanup.
 
In the example below we create a local cluster in a script operation. The cluster deletion script is added to the finally block, guaranteeing the cluster will be deleted regardless of the test outcome.

Operations defined in the try block are executed first, then:
 
     
  • If an operation fails to execute, Chainsaw won't execute the remaining operations and will execute all operations defined in the catch block instead (if any).
    •  
  • If all operations succeed, Chainsaw will NOT execute operations defined in the catch block (if any).
    •  
  • Regardless of the step outcome (success or failure), Chainsaw will execute all operations defined in the finally block (if any).

Tip
 
Note that all operations coming from the catch or finally blocks are executed. If one operation fails, Chainsaw will mark the test as failed and continue executing with the next operations.

Under certain circumstances, it can be useful to configure catch blocks at a higher level than the step grain. At the test or configuration level.
 
This allows for declaring common catch statements we want to execute when an error occurs. Those catch blocks are combined to produce the final catch block in the following order:
 
     
  1. catch statements from the configuration level are executed first (if any)
    2.  
  2. catch statements from the test level are executed next (if any)
    3.

"},{"location":"test/#what-is-a-test","title":"What is a test?","text":"
To put it simply, a test can be represented as an ordered sequence of test steps.
 
In turn, a test step can be represented as an ordered sequence of operations.
 
     
  • When an operation fails the test is considered failed

  • If all operations succeed the test is considered successful

"},{"location":"test/#definition-approach","title":"Definition approach","text":"
Chainsaw supports two different test definition approaches:
 
Tip
 
While Chainsaw supports two test definition approaches, we strongly recommend the explicit one.
 
     
  • The explicit approach (strongly recommended)
    •  
  • The conventional approach

Warning
 
While Chainsaw supports the conventional approach, we strongly recommend the explicit one.
 
If you are new to Chainsaw we suggest you skip this section and jump directly to the Explicit approach.
"},{"location":"test/conventional/#introduction","title":"Introduction","text":"
The conventional approach is the simplest and less verbose one.
 
You provide bare Kubernetes resource manifests and Chainsaw will use those manifests to create, update, or assert expectations against a cluster.
"},{"location":"test/conventional/#limitations","title":"Limitations","text":"
While this syntax is simple, it suffers lots of limitations. It doesn't support deletion operations, commands, scripts, and all Chainsaw helpers.
 
It is also impossible to specify additional configuration per test, step or individual operation (timeouts, additional verifications, etc...), making this approach highly limited.
 
It also relies a lot on file naming conventions which can be error prone.
 
Finally, this approach doesn't encourage reusing files across tests and leads to duplication, making maintenance harder.
"},{"location":"test/conventional/#file-naming-convention","title":"File naming convention","text":"
Manifest files must follow a specific naming convention: 
<step index>-<name|assert|errors>.yaml\n
 
As an example, 00-configmap.yaml, 01-assert.yaml and 02-errors.yaml are valid file names.
"},{"location":"test/conventional/#assembling-steps","title":"Assembling steps","text":"
It's perfectly valid to have multiple files for the same step.
 
Let's say we have the following files 00-resources.yaml, 00-more-resources.yaml, 00-assert.yaml and 00-errors.yaml:
 
     
  • 00-resources.yaml and 00-more-resources.yaml contain resources that will be applied in step 00
    •  
  • 00-assert.yaml contains assert statements in step 00
    •  
  • 00-errors.yaml contains error statements in step 00
    •  
 
With the four files above, Chainsaw will assemble a test step made of the combination of all those files.
"},{"location":"test/conventional/#loading-process","title":"Loading process","text":"
The logic to determine the content of a step is always:
 
     
  • The step index is obtained from the beginning of the file name, it must be composed of two numbers between 0 and 9 (from 00 to 99)
    •  
  • The next character acts as a separator and is expected to be -
    •  
  • The rest of the file name (without extension) is then evaluated
       
    • If it is equal to assert, the content is considered assertion statements
      •  
    • If it is equal to error, the content is considered error statements
      •  
    • Else the content is considered resources to be applied
      •  
     
    •  
  • The extension must be .yaml or .yml

The manifest below contains a config map in a file called 01-configmap.yaml. Chainsaw will associate this manifest with an apply operation in step 01.

"},{"location":"test/conventional/#conclusion","title":"Conclusion","text":"
This test will first create a config map, then assert the content of the config map contains the foo: bar data, and then verify that the config map does not contain the lorem: ipsum data.
 
For such a simple test, the conventional approach works reasonably well but will quickly become limited when the test scenarios get more complex.
 
Look at the explicit approach for a lot more flexible solution.
"},{"location":"test/explicit/","title":"Explicit approach","text":"
The explicit is a bit more verbose than the conventional one but offers far more flexibility and features:
 
     
  • It does not rely on file naming conventions for operations ordering
    •  
  • It encourages file reuse across tests, reducing duplication and maintenance
    •  
  • It offers the flexibility to provide additional configurations like timeouts, complex logic, etc...

At the end of the test, Chainsaw cleans up resources it created during the test, in the opposite order of creation.
 
By default, when a step fails, Chainsaw stops the execution and the remaining steps are not executed. The cleanup process starts at the moment the test stops executing.
 
Tip
 
Note that when a failure happens during cleanup, the test is marked as failed and Chainsaw continues executing cleanup for the remaining steps.
