One of the goals of the release 17.1 was to add functional test coverage. Running Behat tests (with Selenium + ChromeDriver) has proven to be a somewhat instable test setup.

To address that, Github Actions have been used combined with a test setup based on Docker containers. This works fine for now for all other QA tests. However running all behat tests on Github actions does not function perfectly yet.

What holds back the test setup is mainly the use of Symfony Assetic combined with MOPA bootstrap bundle. Symlinks used for building the mopa bootstrap assets are not working correctly.

See the tasklist below for more details about the work to be done

After discussion with the team we decided not to drop Assetic for now. We do want to move to Symfony Encore in due time. But this is no requirement at this moment. Removing the Mopa Bootstrap bundle was priority though. (Michiel Kodde - Apr 9, 2020)
