  This test runs the scenario test located in the sub directory.
  Every python file in the sub directory will be executed against pytest.
  
  Optionally, a setup.py file may exist inside the subdirectory in which case
  setup.py is effectively "sourced" before any of the tests are run. This allows
  setup.py to modify environment variables which will be picked up by the
  tests.
  
  For instance, if the PATH variable is changed in setup.py a different python
  environment may be used to run pytest
