Automatically inject service to Behat Context as constructor argument

You can enable the Behat service autowiring feature to get the services automatically injected to Contexts. E.g.:

Feature:

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:

<?php

use Behat\Behat\Context\Context;
use Exception;
use Magento\Catalog\Api\ProductRepositoryInterface;

class YourContext 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 :)
    }
}

Configuration:

default:
  suites:
    yoursuite:
      autowire: true

      contexts:
        - YourContext
