You might want to make the test more abstract now (testing compiler pass each service separately, with all 4 and maybe with none). 👍 nonetheless.

[Steveb-p]

Merging this will unblock tests that use the IbexaTestKernel.

[Steveb-p]

Currently blocks ibexa/migration master branch tests and the new commerce. Shall we merge, or are we waiting for more reviews / QA?

@Steveb-p there's a strange issue on Travis where the browser tests are not able to log in on some setups on Symfony 5.3, something @webhdx will need to investigate (next week I guess?)

[lserwatka]

Yes, we are not ready for SF 5.3. We need to debug issue @mnocon mentioned.

[Steveb-p]

Could we split the version bump and the changes to the compiler pass?

As it stands it blocks the integration tests on anything that uses application kernel for that (due to session handlers not being defined).

I wanted to fix that with #41, but since this PR covers the same code (and expands upon changes, with 5.3 compatibility) I've closed that one.
