I would like to use nose2 with coverage plugin to get the coverage of a Python package but I'm have a hard time configuring it to cover only the package I'm working on. The package is called vimhdl and the coverage section of my unittest.cfg looks like this:
[coverage]
coverage = vimhdl
With nose2, the result doesn't include all files from the package (maybe because of Coverage.py warning: Module vimhdl was previously imported, but not measured. message, but I don't know how to fix it).
Also, when opening the HTML report for a given file, statements such as import logging and modules' doc strings are marked as not covered.
$ nose2 --with-coverage -vvv

On the other hand, with nosetests, the result include all files as expected.

How do I configure nose2 coverage plugin to cover only a given module?
The source code is on github at https://github.com/suoto/vim-hdl/tree/unstable if it helps.

Check nosetests --help or nosetests --plugins to find out which coverage plugin is available on your system. If you have Ned Batchelder’s coverage module installed, you may activate a coverage report with the --with-coverage switch or NOSE_WITH_COVERAGE environment variable.
Minimum percentage of coverage for tests to pass [NOSE_COVER_MIN_PERCENTAGE] Include all python files under working directory in coverage report. Useful for discovering holes in test coverage if not all files are imported by the test suite. [NOSE_COVER_INCLUSIVE] class nose.plugins.cover. Coverage ¶
By default, Nose2 does not support parallel test execution, a feature that is extensively used in test automation. However, loading plugins is not tricky in Nose2, as plugin module names can be effortlessly added to the plugins list in the config file’s [unittest] section.
If you want to include those modules too, use the ``--cover-tests`` switch, or set the NOSE_COVER_TESTS environment variable to a true value.
The simplest way to control coverage.py is to use it to run your tests:
coverage run --source=vimhdl -m nose
