  Use timeout in workflows for unit tests to prevent tests from going into an infinite loop. Admins won't need to cancel tests themselves, contributors will receive a quicker feedback.

Problem

My GSoC PR made me think that timeout in the tests is a useful feature so here it is :)

Solution

timeout-minutes set to 30, the exact value is a subject of discussion.

Yes, that makes sense. The timeout AFAIK also only applies on inactivity (no console output), so even if we'd had a test suit that overall ran longer it should still work.

Let's merge that after fix of indentation

Thanks a lot!
