prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Check if we have fallback if no trackerbot URL specified
  We had some issues htat people with no trackerbot URL in config were not able to run test:
  - Investigate what is happening
  - Add fallback (do not check templates at all? Load them from all providers?)

  1 """``setup_provider`` fixture
  2 
  3 In test modules paramatrized with :py:func:`utils.testgen.provider_by_type` (should be
  4 just about any module that needs a provider to run its tests), this fixture will set up
  5 the single provider needed to run that test.
  6 
  7 If the provider setup fails, this fixture will record that failure and skip future tests
  8 using the provider.
