PyCharm, Django: zero code coverage

Question

PyCharm has a \"Run with Coverage\" action for Django test targets. This runs the tests, but shows zero test coverage (0% files, not covered in the project pane, and all red in

Answer 1

I had a similar issue using the PyCharm bundled coverage.py

The tests were running fine, but the coverage results were not loaded, "0%" or "not covered" everywhere.

There was an error logged in the PyCharm console though, following the output of the tests, that was coverage.py related:

/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python 
"/Applications/PyCharm 2.5 EAP.app/helpers/run_coverage.py" 
run "--omit=/Applications/PyCharm 2.5 EAP.app/helpers" bin/test

Creating test database for alias 'default'...
................................
----------------------------------------------------------------------
Ran xx tests in xxs

OK
No source for code: '/path/file.py' (<- error)

Process finished with exit code 0

My solution was to run the bundled coverage.py with the option to ignore errors: "-i".

I've edit the bundled "run_coverage.py" file, you can see its location in the console output, and add the "-i" option in the last line:

main(["xml", "-o", coverage_file + ".xml"])

to:

main(["xml", "-i", "-o", coverage_file + ".xml"])

This worked for me, the error is ignored and all the coverage data are now loaded in the UI.

If using "-i" solve the issue on your side, a better solution would be to fix the errors, but until then, you'll see coverage results.
