[4.x] Finish incomplete and missing tests

[abrardev99]

This PR completes the missing/skipping tests. Now there is only one skipping test related to the Debuggable feature. As discussed internally, this feature is still incomplete, so I left the test as it is.

The ternary I told you to convert to a proper if check — don't overcomplicate it. You're using str() just to join strings and then you have to call ->toString() at the end. That just adds complexity.

Also, the comments aren't needed.

All you need to do there is just change the ternary into an if () and the code will be perfect.
