If Alfredo's advice doesn't fix it, you can also run nose inside
coverage instead of the usual way:<br>
<br>
$ coverage run nosetests.py<br>
<br>
Also, you can specify options to coverage using a .coveragerc file,
so you could for example set the "source=" option to limit
coverage's attention to a particular tree of files.<br>

I can't figure out why I'm getting coverage reports for
standard library modules with the (most excellent) coverage.py
and (also most excellent) nose:<br>
<br>
Python source:<br>
<br>
% cat test.py<br>
"""Demonstrate coverage of library module."""<br>
<br>
import json<br>
<br>
def test_json():<br>
print json.dumps({'a':3})<br>
<br>
<br>
Run nose with coverage:<br>
<br>
% nosetests --with-cover<br>
<br>

<div>You are missing the "--cover-package" flag that specifies
what package to track.</div>
<div><br>
</div>
<div>This is very useful because sometimes you need a report on
a sub-package:</div>
<div>
<br>
</div>
<div>nosetests --with-cover --cover-package=foo.sub_foo</div>
<div><br>
</div>
<div>If you do not provide that flag, you are telling the tool
to track coverage in everything that is touched by your</div>
<div>execution.</div>
