Declaring ::setUp without a void return typehint in tests is deprecated

hi @stevenlafl, thanks for your contribution.

A fatal error has been fixed already in 8.x-1.x-dev; so no action here.

The other part is pretty new, deprecated in 9.0.0:

Provided patch fixes only 3 occurrences (and I'm not sure if it can be committed taking into account D8 is still here)

Updated patch for comment #4 and alos add changes regarding drupal-check for deprecations.

hi @narendra.rajwar27,

Thanks for your contribution. Let's fix it step by step, and not doing everything in one issue.

This one is about setUp() declaration. Other things should be fixed in the follow-up(s).

Hi @Taran2L,
actually i was trying to upload patch for failed test case. So updating only that one but it seems some issue with upload. Surely we can fix further in follow-ups.

As I said before, let's handle setUp here and then other things in a separate issue.
