Python unittest ignore numpy

I am writing python tests with unittest and running the tests from the command line with

 nosetests --with-coverage -x

When I include numpy in one of my tests it tries to test the numpy packages as well. Example output:

OK

How can I correctly ignore the numpy tests with the -I -m or -e parameters? I could pipe this to grep -v numpy but that is not cool.


There is a nose plugin specifically for the task - nose-exclude:

nose-exclude is a Nose plugin that allows you to easily specify directories to be excluded from testing.

Another option is to specify omit configuration parameter in .coveragerc file:

omit (multi-string): a list of filename patterns, the files to leave out of measurement or reporting.

See also: How to exclude mock package from python coverage report using nosetests


You can also specify which package you'd like to run tests for when you call nose with the --cover-package flag.

Eg

nosetests --with-coverage --cover-package=the-name-of-your-package -x
