Parameters in behat.yml

问题

I want to make

behat.yml -

default:
    extensions:
        Behat\MinkExtension\Extension:
            base_url: 'my-url'

a parameter pulled from parameters.yml... Is this possible? I made a mink_base_url parameter in parameters.yml and then added

imports:
    - { resource: parameters.yml }

to behat.yml. No matter what I do, I get this

[Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException]                                
The service "behat.mink.context.initializer" has a dependency on a non-existent parameter "mink_base_url"

回答1:

Behat configuration is in no way related to Symfony's. It's true that Behat uses Symfony's DI container, but it's a separate instance.

If wanted to implement it, you'd probably need to create your own Behat extension to support the imports section.

This worked for me with Symfony 3. Just omit base_url from behat.yml, and set it from the container parameters. Thanks to @DanielM for providing the hint.

<?php

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

class FeatureContext extends MinkContext {
    /**
     * FeatureContext constructor.
     * @param ContainerInterface $container
     */
    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    /**
     * @BeforeScenario
     */
    public function setUpTestEnvironment()
    {
        $this->setMinkParameter('base_url', $this->container->getParameter('my_url'));
    }
}

If you just want to access base_url, you can get it once mink has been started.

$this->getMinkParameter('base_url');

Here's an example :

class AbstractBehatContext extends MinkContext {

    /**
     * The base url as set behat.yml
     * @var bool
     */
    protected $baseUrl;

    /**
     * @BeforeScenario
     */
    public function getBaseUrl() {

        $this->baseUrl = $this->getMinkParameter('base_url');

    }

}

Note, this needs to be able to access Mink, so it won't work in __construct or in @BeforeSuite. Additionally @BeforeScenario will be called at the start of every scenario which is going to set it pointlessly a lot.

It is possible to access the symfony parameters within behat yaml as using

- '%%name_of_the_parameter%%'

Double percentage sign (%%) does the trick.
