python nose coverage plugin too thorough (forced pylib option)

Question

I am using nose 1.3.0 and coverage 3.7.

Running on a command line

coverage run test_myfile.py
coverage report

produces a report that limits itself to the functions in myfile.py:

Name               Stmts   Miss Branch BrMiss  Cover
----------------------------------------------------
myfile               157     27     38     12    80%
test_myfile           81     16     16     13    70%
----------------------------------------------------
TOTAL                238     43     54     25    77%

If however I try to use the coverage plugin for nose, coverage extends to the installed python libraries with is slow and clutters the results:

nosetests --with-coverage myfile.py

Here coverage extends to all used packages from the installed libraries in all their gory detail (report manually shortened):

Name                                                    Stmts   Miss Branch BrMiss  Cover   Missing

This seems to be equivalent to specifying on the command line:

coverage run --pylib test_myfile.py

How can I get the nose coverage plugin to not delve into the installed python libraries?

Answer 1

You should configure it. Here's an example:

# .coveragerc
[report]
include = *.py
omit =
    tests.py
    *_test.py
    *_tests.py
    */site-packages/*
    */migrations/*

Answer 2

I think you may want to try something like this:

nosetests --with-coverage --cover-package=myfile --cover-tests
