Coverage.py warning: No data was collected. (no-data-collected)

Question

I am trying to find the coverage using coverage module for a django project but gets

Coverage.py warning: No data was collected. (no-data-collected)
         


        

Answer 1

I encountered this error with tox:

Coverage.py warning: No data was collected. (no-data-collected)

My configuration performs an install of the module and tests that rather than the source code. However, test discovery was finding a module that I had named test_*.py in my app package, causing PYTHONPATH confusion and resulting in failure to collect coverage details. Renaming the module to not start with test_ resolved the issue.
