how to disable nose test's coverage report

Question

Hopefully a simple python/django nose test question, though I can't find the answer in nose's documentation.

How do I stop the coverage report showing up after I run the tests with ./manage.py test?

I have a huge problem with the coverage report forcing me to scroll back a few dozen lines to get the traceback of my failing test, it really interrupts my workflow! I like using nose, but if I can't figure out how to get rid of this I'll have to go back to vanilla django tests.

Thanks in advance for your thoughts!

Here's what I have to scroll back through to get to the traceback:

./manage.py test

Answer 1

Which versions of Django and nose are you using? As far as I'm aware, this is not the default behaviour of Django's test running and it's definitely not default for nose.

The relevant option to give to nose to toggle use of the coverage plugin is "--with-coverage".

I'm not sure you managed to turn coverage on by accident, you should look in settings.py for variables like COVERAGE_MODULES and TEST_RUNNER and see what they're set to.

Answer 2

You can:

pip install nose-cov

Which has more control over reporting options and will not report to console unless you ask it to. Then change --with-coverage to --with-cov:

NOSE_ARGS = [
 '--with-cov',
 '--cov-report', 'html',
]

This will only export to html.

Same question here:
