[TIP] coverage.py has slightly different results when being called from setup.py and not...

[Tom Swirly]

Greetings, testy people.  Thanks for this excellent package!


I discovered coverage.py last week and have been dropping it into various
projects I'm on.  One of them only has a strangeness and I'd like to figure
it out.

The project is quite vanilla and doesn't use any of the trouble techniques
listed here:  https://coverage.readthedocs.io/en/coverage-4.3.4/trouble.html


--timid had no effect.


The issue: when I run coverage from setup.py <http://coverage run -m
unittest discover test \*_test.py> this file gamma.py
<https://github.com/ManiacalLabs/BiblioPixel/blob/dev/bibliopixel/gamma.py> is
marked as having only 6% coverage - nothing except line 14
<https://github.com/ManiacalLabs/BiblioPixel/blob/dev/bibliopixel/gamma.py#L14>.


I don't even see how that would be possible, but more, there's an explicit
test that at least loads the file
<https://github.com/ManiacalLabs/BiblioPixel/blob/dev/test/gamma_test.py>,
even if it doesn't test the values - and yes, I can see that test run in my
results.

If I run coverage.py from the command line, like this:

coverage run -m unittest discover test \*_test.py .


 I see 100% coverage as expected.



Generally, I hate hitting up mailing lists until I have had a chance to
debug the package I'm whining about ;-), but in this case I'm really not
quite sure how to debug coverage.py, and I see no bug report I can camp on.
 (I don't think this one
<https://bitbucket.org/ned/coveragepy/issues/280/allow-test-suite-run-via-python-setuppy>
is it...)

Thanks in advance!
