将自定义服务注入Behat上下文

Question

Is it possible to build and inject my own, custom services into a Behat Context class?

I'm integrating Behat with Symfony2, and I can inject Symfony's services into my contexts like so:

contexts:
    - Meeebu\MyBundle\Features\Security\Context\SecurityContext:
        session:    '@session'

provided that the Behat\\Symfony2Extension is registered.

I'm also using Behat Page Object Extension that injects Page objects into Context constructor directly, so my constructo currently looks like this:

public function __construct(Session $session, Homepage $homepage, WelcomeAdmin $welcomeAdminPage)

Now, I'd like to use my owe custom services in the Context class.

How can I create, register, and inject them in Behat?

Answer 1

you need to create and register a behat extension: https://github.com/Behat/Behat/blob/2.5/src/Behat/Behat/Extension/ExtensionInterface.php

and then register your service (or load an yml/xml/etc. file) in the load method. and then add an extension class to the behat.yml, to the extensions section.
