Codeception fails to find Kernel.php in Symfony 4

Question

I'm trying to use Codeception to make some functional acceptance tests on project using Symfony 4. Project environment is built with docker containers(just simple pgsql container and php container that run php bin/comnsole serve and expose 8000 to different local port). I've met the problem that running tests specified with symfony extension causes an error:

bin/codecept run -v
Codeception PHP Testing Framework v2.4.0
Powered by PHPUnit 7.0.2 by Sebastian Bergmann and contributors.

In Symfony.php line 300:

  [Codeception\Exception\ModuleRequireException]
  [Symfony] module requirements not met --

  Kernel class was not found in /srv/dsp-blacklister/src/Kernel.php. Specify directory where file with Kernel class for your application is located with `app_path` parameter.

But Kernel is situated there:

/srv/dsp-blacklister/src # ls -la

Your kernel is in a different namespace. There isn't a fix for this yet, other than the temporary hack below (add to the bottom of your kernel class)

class_alias(Kernel::class, 'App\Kernel', true);

The problem is on the Symfony.php file on codeception, It tries to load appKernek or app/Kernel. I fixed with the solution shown above.

Now you can use the kernel_class parameter to specify the kernel namespace:

modules:
    enabled:
        - \Helper\Functional
        - Symfony:
            kernel_class: AppTest\Kernel

For Codeception v5.0.5 adding to all suits:

modules:
    enabled:
        - Symfony:
            app_path: 'src'
            environment: 'test'

worked for me.
