excluding packages/directories

[Nikola Skoric]

How do I exclude certain packages from being displayed in report? I figured out that in coverage I do it with --omit flag, but can't figure it out in nosetests. Nose in it's report lists several packages I didn't even know I use (albeit listing them as 0% tested, which is good) and that clutters the report and slows my workflow. Here is my test session:

nick@rilmir:~/code/travapi$ cat runtest.sh                                                  
#!/bin/bash                                                                                 
export PYTHONPATH=$PYTHONPATH:~/code/travapi/travapi/
echo "Runing nosetests..."                          
nosetests --with-coverage                           
echo "Creating coverage HTML report..."             
coverage html                                       
echo "Done."                                        
nick@rilmir:~/code/travapi$ ./runtest.sh

    def __str__

omit = /usr/local/lib/python2.6/dist-packages
nick@rilmir:~/code/travapi$ coverage report

So, coverage got it all right when I set the "omit" flag. Is there a way to make nose forget about all those standard libraries and stuff from my dist-packages?

Kind regards,
Nikola

Nikola, I think you are confusing what nose does and what coverage.py
does. Nose does one thing: finds tests and runs them. Coverage.py does
another thing: measures code execution and reports what it finds. The
modules you see in the coverage report are really executed, and nothing
you tell nose will make them not be executed. _LWPCookieJar is a module
that is somehow eventually imported by your tests. I don't quite
understand the 0% coverage, but it isn't a nose issue.

OK, let me rephrase the problem: when I run "nosetests --with-coverage" from shell, "nosetests --with-coverage" returns me a report that has some libraries in it which I don't want to see there. How do I remove them from there (be it coverage problem or nose problem or whatever)?

It's just that what "nosetests --with-coverage" returns to me is full of data I'm not interested in and I'd like to see that data out or my everyday life. If the answer is "you can't get it our", no problemo, I can live with that. I just had to ask :-)

Sorry for being pain in the ass :-D

Regards,
Nikola

The nose plugin for coverage has an option like --cover-package that you can use to white list the modules you're interested in seeing in your report.

You can omit packages from reporting in coverage.py with the omit option in the .coveragerc file.  The odd thing here is that the modules reported as 0% are all stdlib modules.  They must have been imported before coverage measurement started to have 0% coverage.  If you run coverage outside of nose (with "coverage run nosetests-script.py ..."), the problem will likely go away, though you may have other difficulties.

I tired that before and it didn't work... but it didn't work because I used relative path. Now I used absolute path to my package and now everything works like a charm.

Thank you Paul and Ned for being so helpful, I hope one day I will also be able to contribute to world of free software and help somebody else :-)

Regards,
Nikola
