README

The JSON API Behat Extension provides step definitions for common testing scenarios specific to JSON APIs. It comes with easy ways to handle authentication through OAuth.

Requirements

• PHP >= 5.4

Installation

Recommended installation is by running the composer require command. This will install the latest stable version of this extension.

composer require kielabokkie/jsonapi-behat-extension --dev

Configuration

To use this extension you will have to add it under the extensions in your behat.yml file.

default:
    extensions:
        Kielabokkie\BehatJsonApi: ~

Default parameters

Out of the box this extension has the following default parameters:

You can overwrite any of these parameters in the behat.yml file as needed.

default:
    extensions:
        Kielabokkie\BehatJsonApi:
            base_url: http://api.yourapp.dev
            parameters:
                oauth:
                    uri: /v1/oauth/token
                    client_id: myClientId
                    client_secret: myClientSecret
                    use_bearer_token: true
                    password_grant_requires_client_credentials: true

Optional parameters

To avoid having to use OAuth to retrieve an access token for each API call you can also specify an optional access_token in the parameters:

default:
    extensions:
        Kielabokkie\BehatJsonApi:
            parameters:
                access_token: 90dabed99acef998fd3e35280f2a0a3c30c00c8d

Usage

To use the step definitions provided by this extension just load the context class in your suites:

default:
  suites:
    default:
      contexts:
        - Kielabokkie\BehatJsonApi\Context\JsonApiContext

You will then have access to the following step definitions:

@Given I use the access token
@Given I use access token :token
@Given I oauth with :username and :password
@Given I oauth with :username and :password and scope :scope
@Given I oauth using the client credentials grant
@Given I oauth using the client credentials grant with scope :scope
@Given I oauth using the client credentials grant with :id and :secret
@Given I oauth using the client credentials grant with :id and :secret and scope :scope
@Given I add a :header header with the value :value
@Given I have the payload:
@When /^I request "(GET|PUT|PATCH|POST|DELETE) ([^"]*)"$/
@Then I get a :statuscode response
@Then scope into the :scope property
@Then scope into the first :scope element
@Then the structure matches:
@Then the :field property is an object
@Then the :field property is an array
@Then the :field property is an array with :count items
@Then the :field property is an empty array
@Then the :field property is an integer
@Then the :field property is a integer equaling/equalling :expected
@Then the :field property is a string
@Then the :field property is a string equaling/equalling :expected
@Then the :field property is a boolean
@Then the :field property is a boolean equaling/equalling :expected
@Then /^echo last request$/
@Then /^echo last response$

Note: The last two definitions are for debugging purposes and only show output when you use the pretty formatting option of Behat, i.e. ./vendor/bin/behat -f pretty.

To get a list of all available step definitions including examples you can run the following command:

$ vendor/bin/behat -di

Override the base url

In some cases you might want to override the base url for a specific suite. Below is an example of a behat.yml file. Here the custom url http://hooks.yourapp.dev is passed to the FeatureContext under the hooks suite.

default:
    autoload:
        - %paths.base%/tests/Behat/features/bootstrap
    suites:
        api:
            paths:
                - %paths.base%/tests/Behat/features/api
            contexts:
                - Kielabokkie\BehatJsonApi\Context\JsonApiContext: ~
        hooks:
            paths:
                - %paths.base%/tests/Behat/features/hooks
            contexts:
                - Kielabokkie\BehatJsonApi\Context\JsonApiContext:
                    - http://hooks.yourapp.dev
    extensions:
        Kielabokkie\BehatJsonApi: ~
