Configuration reference

By default, if no confguration is passed, SymfonyExtension will try its best to guess it. The full configuration tree looks like that:

# behat.yml.dist / behat.yml

default:
    extensions:
        FriendsOfBehat\SymfonyExtension:
            bootstrap: ~
            kernel:
                class: ~
                path: ~
                environment: ~
                debug: ~

  • bootstrap:

    It is a path to the file requried once while the extension is loaded. You can use this file to set up your testing environment - set some enviornment variables or preload an external file. If you do not pass any, it would look for either config/bootstrap.php (Symfony 4) or app/autoload.php (Symfony 3). If none are found, no file would be loaded.

  • kernel.class:

    It is a fully qualified class name of the application kernel class. If you do not pass any, it would look for either App\Kernel (Symfony 4) or AppKernel (Symfony 3). If none are found, an exception would be thrown and you would be required to specify it explicitly.

  • kernel.path:

    It is a path to the file containing the application kernel class. You might want to set it if your kernel is not autoloaded by Composer's autoloaded. If kernel.class is not defined, it would automatically use app/AppKernel.php if AppKernel class was autoconfigured.

  • kernel.environment:

    It allows you to force using a given environment. If it is not set, it uses APP_ENV environment variable if defined or falls back to test.

  • kernel.debug:

    It allows you to force enabling or disabling debug mode. If it is not set, it uses APP_DEBUG environment variable if defined or falls back to true.
