Thanks @mikadamczyk 🎉 This is very much needed refactoring.

Overall please see SonarLint analysis and address issues related to your changes, according to our internal sync. Also please restore dropped FQCN in PhpDocs.

Some specifics:

Just for info - tests were intentionally written in that style, because the idea was to extract the parts between /* BEGIN: Use Case */ and /* END: Use Case */ with a script and use it to automatically generate API examples for documentation. With this change the tests are not usable for that any longer, as the code does not read easily if embedded without context. So you could remove the markers as well.

BTW, the extraction script should still be somewhere in the repository.

Thanks @pspanja for your input! I didn't know that :)

Thank you for your explanation @pspanja :)

No QA required - only integration test changes. Merging, thank you @mikadamczyk!
