inanzzz | Creating sub context and accessing its resources from other context files in behat

If you want to create a new sub context class and dedicate it to a behat feature file, you can use example below. Rather than putting everything in a FeatureContext class, it is ideal to create sub context classes and share some logic in between.

FeatureContext

namespace Application\FrontendBundle\Features\Context;

use Behat\MinkExtension\Context\MinkContext;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;

class FeatureContext extends MinkContext implements ContainerAwareInterface
{
    const SAY_HELLO = 'Hello';

    private $container;

    public function __construct()
    {
        $this->useContext('you_context', new YouContext());
        $this->useContext('me_context', new MeContext());
    }

    public function setContainer(ContainerInterface $container = null)
    {
        $this->container = $container;
    }

    public function sayHello()
    {
        return self::SAY_HELLO;
    }
}

YouContext

namespace Application\FrontendBundle\Features\Context;

use Behat\Behat\Context\BehatContext;

class YouContext extends BehatContext
{
    /**
     * @Then /^I can access YouContext step definition$/
     */
    public function iCanAccessYouContextStepDefinition()
    {
        return true;
    }
}

MeContext

namespace Application\FrontendBundle\Features\Context;

use Behat\Behat\Context\BehatContext;
use Behat\Behat\Exception\BehaviorException;

class MeContext extends BehatContext
{
    /**
     * @Then /^I can access MeContext step definition$/
     */
    public function iCanAccessMeContextStepDefinition()
    {
        return true;
    }

    /**
     * @Then /^I can access FeatureContext resources from MeContext$/
     */
    public function iCanAccessFeatureContextResourcesFromMeContext()
    {
        /** @var FeatureContext $mainContext */
        $mainContext = $this->getMainContext();

        if ($mainContext->sayHello() != $mainContext::SAY_HELLO) {
            throw new BehaviorException('Cannot access FeatureContext resources.');
        }
    }
}

Behat feature

Feature: .......

  Scenario: I can access step definitions of other context files
    Given I can access YouContext step definition
    And I can access MeContext step definition
    And I can access FeatureContext resources from MeContext

Result

$ bin/behat --profile=frontend
Feature: ....

  Scenario: I can access step definitions of other context files
    Given I can access YouContext step definition
    And I can access MeContext step definition
    And I can access FeatureContext resources from MeContext
