Behat 3 + Symfony 3 Context with namespace doesn't work, when without works

Question

I have the following catalogs structure :

composer.json
behat.yml
src
|--AppBundle
   |--Features
      |--example.feature
      |--Context
         |--FeatureContext.php

And the following behat.yml

default:
  autoload:
    '': 'src/AppBundle/Features/Context'
  suites:
    default:
      paths: ['src/AppBundle/Features']
      contexts:
        - FeatureContext:
          session: '@session'
    # and extensions standard for Symphony

And FeatureContext.php contains

<?php

//namespace AppBundle\Features\Context;

use Behat\Behat\Context\Context;
use Behat\MinkExtension\Context\MinkContext;

/**
 * Defines application features from the specific context.
 */
class FeatureContext extends MinkContext implements Context
{   ...   }

There is commented namespace . When I run behat, now context is found correctly. When I uncomment namespace there occurs error:

[Behat\\Behat\\Context\\Exception\\ContextNotFoundException]
FeatureContext context class not found and can not be used.

How to make it working when namespace in FeatureContext.php is uncommented? I do not know much about PSR-0 and PSR-4, but if problem can be connected with this i append fragment of composer.json .

"autoload": {
    "psr-4": {
        "": "src/"
    },
    "classmap": [
        "app/AppKernel.php",
        "app/AppCache.php"
    ]
},
"autoload-dev": {
    "psr-4": {
        "Tests\\": "tests/"
    }
},

I looking for best practices of coding, so if I am doing something in bad way I vote up for appropriate suggestion.

• I seem I should have namespace in FeatureContext.php , shouldn't I?
• I seem I shouldn't use PSR-0 in composer.json , should I?

Have a look at the example below. Full example is here: http://www.inanzzz.com/index.php/post/l41o/testing-a-basic-auth-symfony-api-with-behat3 You can also find more behat examples here: http://www.inanzzz.com/index.php/posts/behat

Note 1: You can access the session in context files directly so no need to inject it. You might need to use implements KernelAwareContext or implements KernelAwareInterface or implements ContainerAwareInterface . Just check the blog posts above.

Note 2: You don't need autoload-dev in composer.sjon at all. Get rid of it.

composer.json

Note: Use new versions!

{
    "require-dev": {
        "behat/behat": "3.0.15",
        "behat/symfony2-extension": "2.1.0",
        "behat/mink": "1.7.0",
        "behat/mink-extension": "2.1.0",
        "behat/mink-browserkit-driver": "1.3.0"
    },
}

behat.yml

default:
    extensions:
        Behat\Symfony2Extension: ~
        Behat\MinkExtension:
            base_url: http://your_local_app_domain.com/app_test.php/
            sessions:
                symfony2:
                    symfony2: ~
    suites:
        api:
            type: symfony_bundle
            bundle: ApplicationApiBundle
            mink_session: symfony2
            contexts:
                - Application\ApiBundle\Features\Context\FeatureContext:
                    param: 'whatever'

FeatureContext.php

namespace Application\ApiBundle\Features\Context;

use Behat\MinkExtension\Context\MinkContext;

class FeatureContext extends MinkContext
{
    private $param;

    public function __construct($param)
    {
        $this->param = $param;
    }

    ......
}

Test

$ bin/behat --suite=api @ApplicationApiBundle/YourFeature.feature
