JSON API Behat Extension

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.

NOTE: This extension is still being developed and can't be installed as described below

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

Or alternatively you can manually add the package to your composer.json file.

"require-dev": {
    "kielabokkie/jsonapi-behat-extension": "~1.0"
},

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 this extension has the following default parameters:

parameter	value
base_url	http://localhost:8000
oauth_uri	/v1/oauth/token
oauth_client_id	testclient
oauth_client_secret	testsecret
oauth_use_bearer_token	false
oauth_password_grant_requires_client_credentials	false

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 prevent having 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 you need to modify your FeatureContext.php file to extend the JsonApiContext instead of the standard BehatContext and call the parent::construct() method in the constructor.

<?php

use Kielabokkie\BehatJsonApi\Context\JsonApiContext;

/**
  * Defines application features from the specific context.
  */
class FeatureContext extends JsonApiContext
{
    /**
     * Initializes context.
     */
    public function __construct()
    {
        parent::__construct();
    }
}

When you've made the changes above to your FeatureContext class you get 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 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$

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