• Branch behat2 : Behat 2.x
• Branch master : Behat 3.x

For now only JSON api is supported to analyze response, but you could use REST part to perform request on any type of api.

Don't forget to load the extension and the context if needed in your behat.yml :

default:
    extensions:
        Rezzza\RestApiBehatExtension\Extension:
            rest:
                base_url: http://localhost:8888
                store_response: true
                adaptor_name: curl # Should be one of these adapters : https://github.com/egeloen/ivory-http-adapter/blob/master/doc/adapters.md#factory
    suites:
        default:
            contexts:
                - Rezzza\RestApiBehatExtension\RestApiContext
                - Rezzza\RestApiBehatExtension\Json\JsonContext

Regarding the adaptor_name you choose, you will have to install the deps needed on your own.

You can use directly the JsonContext or RestApiContext by loading them in your behat.yml or use the RestApiBrowser and JsonInspector by adding them in the construct of your own context.

<?php
/**/

use Rezzza\RestApiBehatExtension\Rest\RestApiBrowser;
use Rezzza\RestApiBehatExtension\Json\JsonInspector;

class FeatureContext implements Context
{
    private $restApiBrowser;

    private $jsonInspector;

    public function __construct(RestApiBrowser $restApiBrowser, JsonInspector $jsonInspector)
    {
        $this->restApiBrowser = $restApiBrowser;
        $this->jsonInspector = $jsonInspector;
    }
}
