How do I overwrite the Symfony2 semantic configuration per environment?

Question

parameters.yml:

time_limit:        8

my_ui.yml:

my_ui:
    time_limit: %time_limit%

config.yml:

Answer 1

Override any parameter in your config_test.yml file and make sure you make requests to the app_test.php controller when executing functional tests. If that controller doesn't exist, copy it from app_dev.php changing

$kernel = new AppKernel('dev', true);

to

$kernel = new AppKernel('test', true);

For example, I use the bcrypt password encoder that causes passwords to be encoded in 1-2 seconds each time. This is not acceptable for tests, so I override the cost to the minimal value in config_test.yml to speed up tests:

security:
    encoders:
        Elnur\Model\User:
            algorithm: bcrypt
            cost: 4

This way in production the cost would be 14, but in testing just 4.
