| Automatically inject service to Behat Context as constructor argument | ||
| ===================================================================== | ||
|
|
||
| You can enable the `Behat service autowiring feature <https://github.com/Behat/Behat/pull/1071>`_ to get the services automatically injected to Contexts. E.g.: | ||
|
|
||
| **Feature:** | ||
|
|
||
| .. code-block:: gherkin | ||
| Feature: Magento and Behat DI connected | ||
| As a developer | ||
| In order to write Behat tests easily | ||
| I should be able to inject services from the Magento DI into Behat Contexts | ||
| Scenario: Injecting service from Magento DI to Behat Context as argument for Behat Context constructor | ||
| Given A service has been successfully injected through the Context constructor | ||
| When I work with Behat | ||
| Then I am happy | ||
| **Context:** | ||
|
|
||
| .. code-block:: php | ||
| <?php | ||
| use Behat\Behat\Context\Context; | ||
| use Exception; | ||
| use Magento\Catalog\Api\ProductRepositoryInterface; | ||
| class FeatureContext implements Context | ||
| { | ||
| /** @var ProductRepositoryInterface */ | ||
| private $productRepository; | ||
| public function __construct(ProductRepositoryInterface $productRepository) | ||
| { | ||
| $this->productRepository = $productRepository; | ||
| } | ||
| /** | ||
| * @Given A service has been successfully injected through the Context constructor | ||
| */ | ||
| public function theProductRepositorySuccessfullyInjectedAsConstructorArgument() | ||
| { | ||
| if (!$this->productRepository instanceof ProductRepositoryInterface) { | ||
| throw new Exception('Something went wrong :('); | ||
| } | ||
| } | ||
| /** | ||
| * @When I work with Behat | ||
| */ | ||
| public function iWorkWithBehat() | ||
| { | ||
| // no-op | ||
| } | ||
| /** | ||
| * @Then I am happy | ||
| */ | ||
| public function iAmHappy() | ||
| { | ||
| // no-op :) | ||
| } | ||
| } | ||

| Inject service to Behat Context as Behat Step Argument Transformer argument | ||
| =========================================================================== | ||
|
|
||
| The `Behat service autowiring feature <https://github.com/Behat/Behat/pull/1071>`_ allows to inject services from the configured service container to any of the `Step Argument Transformer <http://behat.org/en/latest/user_guide/context/definitions.html#step-argument-transformations>`_ method as argument. You can use this feature in combination with this extension as well. E.g.: | ||

| } catch (NoSuchEntityException $e) { | ||
| // product does not exsits - normally you would let the test fail here | ||
| // but for this demonstration we will just create a new product in memory | ||
