  # this is unusual to have a job that checks the unstable tests.
  #
  # reason: some tests are unstable, they works, but not always;
  #         this job checks that they are working sometimes.
  #         if this job fails, then a tests switched from "unstable" to "broken".
  #
  #         summary: this job checks that "unstable tests" do not become "broken tests".
  #
  # we hope we can remove this job because all the tests are stable 100% of the time :)
