Run tests on release branch

[Czaki]

Description

Based on this comment, I would like to enable tests when working with the release branch. I assume that such a branch will have the name in the format v{release_number}x as it happens for 0.4.16 and 0.4.17 releases.

Type of change

• Bug-fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

References

How has this been tested?

• example: the test suite for my feature covers cases x, y, and z
• example: all tests pass with my change
• example: I check if my changes works with both PySide and PyQt backends
  as there are small differences between the two Qt bindings.

Final checklist:

• My PR is the minimum possible work for the desired functionality
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• If I included new strings, I have used trans. to make them localizable.

+1, how would we notice failures ? A Bot posting comments ? I think the comprehensive failures on main branch are already mostly ignored, should have something more noticeable ?

[Czaki]

I think tak release manager will not ignore failures.

In the context of main branch we need some responsible person that is hard if most persons are volunteering.

Seems reasonable to me!
