@evakhoni please, check out the tests: a couple of PRs earlier, the output of report/display plugin changed, therefore some asserts no longer match. After a rebase, it should be easy to reproduce.

Merged by mistake - I think I left automerge enabled, and once @evakhoni rebased, the mandatory checks were missing & Github ignored them. There is a new PR to address https://github.com/teemtee/tmt/pull/3685#issuecomment-2884856788: https://github.com/teemtee/tmt/pull/3749
