Fixtures command

The fixtures command lets you run a json file as a series of API requests. This can be useful for things like filling data, executing specific flows, or testing API behavior.

Specification

Fixtures live in a json file and map to requests. An example file looks like:

{
  "_meta": {
    "template_version": 0
  },
  "fixtures": [
    {
      "name": "cust_bender",
      "path": "/v1/customers",
      "method": "post",
      "params": {
        "name": "Bender Bending Rodriguez",
        "email": "[email protected]",
        "phone": "${.env:PHONE}",
        "source": "tok_amex",
        "address": {
          "line1": "1 Planet Express St",
          "city": "New New York"
        }
      }
    },
    {
      "name": "char_bender",
      "path": "/v1/charges",
      "method": "post",
      "params": {
        "customer": "${cust_bender:id}",
        "amount": 100,
        "currency": "usd",
        "capture": false
      }
    },
    {
      "name": "capt_bender",
      "path": "/v1/charges/${char_bender:id}/capture",
      "method": "post"
    }
  ]
}

Fields

• _meta - contains information specifically for the CLI to read
• _meta.template_version tells the CLI which version of the template is running (allowing us to support possible backwards-incompatible changes)
• fixtures is list of requests to execute
• fixtures[].name is the name of the request, used for reference results later
• fixtures[].path is the relative Stripe URL to make the request to. This supports URL variables as fixture queries
• fixtures[].method the HTTP method for the request
• fixtures[].params an object the API request params to send to Stripe. The values here can be nested JSON objects, strings, integers, booleans, or fixture queries.

Fixture queries

When you give a request a name, the CLI will store the response to use in other requests. The structure of this is:

Accessing attributes in responses: ${name:json_path}
Accessing environment variables: ${.env:VARIABLE_NAME}

Queries must start with ${ and end with }. name is the name of the request assigned as part of the fixture (fixtures[].name) and the json_path is a dot-path to the specific variable requested, for example:

• ${cust_bender:id}: to access a top-level attribute
• ${cust_bender:billing_details.address.country}: to access nested data
• ${cust_bender:subscriptions.data.[0].id}: to access data within a list
• ${.env:PHONE}: to access environment variables, supports .env files
