Unable to run after instalation

[AntonioCS]

Hey,
just followed this article here https://pavlakis.dev/posts/upgrade-to-friends-of-behat-symfony-extension/
to get behat up and running in symfony 4.
I ran the following commands:

composer require --dev friends-of-behat/symfony-extension:^2.0
composer require --dev friends-of-behat/mink friends-of-behat/mink-extension friends-of-behat/mink-browserkit-driver

I then run:

./vendor/bin/behat

and I get the following error:

In ContextServiceEnvironmentHandler.php line 195:
  Kernel "App\Kernel" used by Behat with "local" environment and debug enabled needs to have "FriendsOfBehat\SymfonyExtension\Bundle\FriendsOfBehatSymfonyExtensionBundle" bundle registered.  

Not sure why this isn't using the test env but I went to bundles.php and changed test to all in FriendsOfBehat\SymfonyExtension\Bundle\FriendsOfBehatSymfonyExtensionBundle::class => ['all' => true]
I ran the command again and got this error:

In Validator.php line 61:
  Can not find a matching value for an argument `$kernel` of the method `App\Tests\Behat\DemoContext::__construct()`.  

What am I doing wrong? I basically just installed this

Same here - I was able to narrow down the culprit to \Behat\Behat\Context\ContextFactory::createContext(), but why its happening I don't know. Instead of getting context from container behat tries to instantiate it on its own.

@AntonioCS is your context definiton autoconfigured - autoconfigure: true? Because mine wasn't, after changed it it all started to work.

[AntonioCS]

I have this in services.yaml:

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

and this in services_test.yaml:

services:
    _defaults:
        autowire: true
        autoconfigure: true

This is your main clue and your mistake

Not sure why this isn't using the test env but I went to bundles.php and changed test to all in FriendsOfBehat\SymfonyExtension\Bundle\FriendsOfBehatSymfonyExtensionBundle::class => ['all' => true]

Just revert bundle registration to 'test' and run:

APP_ENV=test ./vendor/bin/behat

[AntonioCS]

@udan this was test and it didn't work

@AntonioCS you can do this

bin/console debug:container -e test demo

it should give you your context:

/app $ bin/console debug:container -e test demo

If not, your services_test.yaml is misconfigured, you need this:

services:
    _defaults:
        autowire: true
        autoconfigure: true

    App\Tests\Behat\:
        resource: '../tests/Behat/*'

@pamil I see you up voted. 😁 IMO this popping up again and again in the issues points to people not understanding how contexts are loaded.

I had the same issue and needed to debug it, found out my test services weren't being loaded (a bug in Symfony IMO), saw that contexts which cannot be loaded from the container fall back to regular Behat behaviour.

This might be too subtle and fragile, I'd make that opt in, but default to using only the container and erroring if not possible. This is very likely to remove most/all issues related to this misconfiguration.

Move your Config to services.yml because services_test.yml ist never read by symfony because Behat runs in dev mode.

Hello @AntonioCS, just encountered the same problem with Symfony 6.2.
To solve the issue, I explicitly set the test environment in the behat.yaml file.
Documented here : https://github.com/FriendsOfBehat/SymfonyExtension/blob/master/DOCUMENTATION.md#configuration-reference

default:
    suites:
        default:
            contexts:
                - App\Tests\Behat\DemoContext

    extensions:
        FriendsOfBehat\SymfonyExtension:
            kernel:
                environment: test
            bootstrap: tests/bootstrap.php

Instead of

default:
    suites:
        default:
            contexts:
                - App\Tests\Behat\DemoContext

    extensions:
        FriendsOfBehat\SymfonyExtension: ~

This works for me. Thanks
