Nosetests & Combined Coverage

Question

I have many projects that I'm programatically running:

nosetest --with-coverage --cover-html-dir=happy-sauce/

The problem is that for each project, the coverage module overwrites the index.html file, instead of appending to it. Is there a way to generate a combined super-index.html file, that contains the results for all my projects?

Thanks.

Answer 1

You can't combine the HTML directories. You can combine the .coverage data files, but you'll have to use coverage directly, rather than through nose:

$ nosetest --with-coverage proj1
$ mv .coverage .coverage.1
$ nosetest --with-coverage proj2
$ mv .coverage .coverage.2
$ coverage combine
(combines .coverage.1 and .coverage.2 into a new .coverage)
$ coverage html --directory=happy-sauce

Answer 2

nosetests --with-coverage -i project1/*.py -i project2/*.py
