I'm writing a standalone bundle and trying to test it. But got an error:

LogicException: Could not find service "test.service_container". Try updating the "framework.test" config to "true".

I couldn't find anything in the documentation related to this error. How can I fix that?

UPD: I tried obvious solution by creating config/config_test.yml and even renamed extension to .yaml but it didn't help, content of the file is:

framework:
    test: true

The content of phpunit.xml.dist (renamed to .txt due to github limitations):
phpunit.txt
