The process used in testing kernel changes is currently based on executing Symfony commands using bundles created for this purposed. These bundles are stored in test link as zip packages. This approach is

I think we should change this approach to extract a kernel qa bundle available as a git repository (ideally available through composer).

This would have following benefits:

• most important: possibility to code review the commands in Pull Requests (making sure that the created commands are correct, knowledge sharing about kernel).
• sharing the bundle is easier (no more zip files, no more "each team member has his own bundle to test this")
• easier setup (a simple composer require instead of generating a symfony bundle and then manually replacing the content)
