A Behat 3 extension for Slim 3

This extension was written based on the Behat Laravel Extension

Can install it with composer through packagist

 composer require --dev pavlakis/slim-behat-extension

On your behat.yml file add the extension within the extensions section

    Pavlakis\Slim\Behat: ~

The above is the minimum setup as long as you are using Akrabat's Slim 3 Skeleton with the default location for settings.php at app/settings.php and behat.yml inside tests/behat.

This is the expected directory structure for the default configuration:

- my_app_dir
|___ app
    |_______ settings.php
    |_______ dependencies.php
|___ tests
    |_________ behat
    	       |_____ behat.yml

If behat.yml is in the root folder, use the following:

default:
  suites:
    default:
      contexts:
        - FeatureContext

  extensions:
    Pavlakis\Slim\Behat:
      config_file: app/settings.php
      dependencies_file: app/dependencies.php
      

Apart from the config (settings.php) all other parameters are optional, however you can also pass:

      config_file: ../../app/configs/settings_test.php
      dependencies_file: ../../app/dependencies.php
      middleware_file: ../../middleware.php
      routes_file: ../../routes.php

In your FeatureContext file

• Include the KernelAwareContext interface
• Include the Pavlakis\Slim\Behat\Context\App trait
• Access the Slim 3 app using $this->app

Feature Context example

Use the logger to log some text to ensure the extension works.

FeatureContext.php

<?php

use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;

use Pavlakis\Slim\Behat\Context\App;
use Pavlakis\Slim\Behat\Context\KernelAwareContext;

class FeatureContext implements Context, KernelAwareContext
{
   use App;

    /**
     * @Then it works
     */

    public function itWorks()
   {
       /** @var \Psr\Log\LoggerInterface $logger */
       $logger = $this->app->getContainer()->get('logger');
       $logger->info("Slim-behat integration works!");
   }

    /**
     * @Given I load the slim-behat extension
     */
    public function iLoadTheSlimBehatExtension()
    {
    }
}
