+# newmanExecute
+
+## Description
+
+This script executes your [Postman](https://www.getpostman.com) tests from a collection via the [Newman](https://www.getpostman.com/docs/v6/postman/collection_runs/command_line_integration_with_newman) command line collection.
+
+## Prequisites
+
+- prepared Postman with a test collection
+
+## Example
+
+Pipeline step:
+
+```groovy
+newmanExecute script: this
+```
+
+This step should be used in combination with `publishTestResults`:
+
+```groovy
+newmanExecute script: this, failOnError: false
+publishTestResults script: this, junit: [pattern: '**/newman/TEST-newman.xml']
+```
+
+## Parameters
+
+| name | mandatory | default | possible values |
+|------|-----------|---------|-----------------|
+| `dockerImage` | no |  |  |
+| `failOnError` | no |  | `true`, `false` |
+| `gitBranch` | no |  |  |
+| `gitSshKeyCredentialsId` | no |  |  |
+| `newmanCollection` | no |  |  |
+| `newmanEnvironment` | no |  |  |
+| `newmanGlobals` | no |  |  |
+| `newmanRunCommand` | no |  |  |
+| `script` | yes |  |  |
+| `stashContent` | no |  |  |
+| `testRepository` | no |  |  |
+
+- `dockerImage` - Docker image for code execution.
+- `failOnError` - Defines the behavior, in case tests fail.
+- `gitBranch` - see `testRepository`
+- `gitSshKeyCredentialsId` - see `testRepository`
+- `newmanCollection` - The test collection that should be executed. This could also be a file pattern.
+- `newmanEnvironment` - Specify an environment file path or URL. Environments provide a set of variables that one can use within collections. see also [Newman docs](https://github.com/postmanlabs/newman#newman-run-collection-file-source-options)
+- `newmanGlobals` - Specify the file path or URL for global variables. Global variables are similar to environment variables but have a lower precedence and can be overridden by environment variables having the same name. see also [Newman docs](https://github.com/postmanlabs/newman#newman-run-collection-file-source-options)
+- `newmanRunCommand` - The newman command that will be executed inside the docker container.
+- `script` - The common script environment of the Jenkinsfile running. Typically the reference to the script calling the pipeline step is provided with the this parameter, as in script: this. This allows the function to access the commonPipelineEnvironment for retrieving, for example, configuration parameters.
+- `stashContent` - If specific stashes should be considered for the tests, you can pass this via this parameter.
+- `testRepository` - In case the test implementation is stored in a different repository than the code itself, you can define the repository containing the tests using parameter `testRepository` and if required `gitBranch` (for a different branch than master) and `gitSshKeyCredentialsId` (for protected repositories). For protected repositories the `testRepository` needs to contain the ssh git url.
+
+## Step configuration
+
+We recommend to define values of step parameters via [config.yml file](../configuration.md).
+
+In following sections the configuration is possible:| parameter | general | step | stage |
+|-----------|---------|------|-------|
+| `dockerImage` |  | X | X |
+| `failOnError` |  | X | X |
+| `gitBranch` |  | X | X |

+| `newmanCollection` |  | X | X |
+| `newmanEnvironment` |  | X | X |
+| `newmanGlobals` |  | X | X |
+| `newmanRunCommand` |  | X | X |
+| `script` | X | X | X |
+| `stashContent` |  | X | X |
+| `testRepository` |  | X | X |
