How to run tests?

[Arve Knudsen]

Hi

I have checked out latest coverage.py from bitbucket, and am trying to
run the testsuite (using nosetests), on Windows 7/Python 2.6. I guess
something is wrong with my setup though, since I get 119 errors and 10
failures. Many of the errors are due to being unable to import
covmodzip1. What do I need to do?

Thanks,
Arve

I found that by entering the 'test' directory before running nosetests
helped, but I still get 4 test errors due to not being able to import
covmodzip1.

I did follow the instructions under the Testing section in howto.txt. That is, I installed a development egg of Coverage.py and created a coverage_test_egg.pth. Running make isn't mentioned.

Now, on my home desktop I get another error when trying to run the tests:

Arve, a quick answer, more later: at the bottom of howto.txt are brief
notes on what needs to be done to run the tests. The Makefile has a
step called testready that will create the egg you need.

Update your nose to 0.11.3.  I understand they only recently got the logic right so that coverage.py's plugin can override theirs.

Thanks, that did the trick.

After reading the Makefile I understood how to create the testdata, and was now more successful. I strongly suggest you document this in your README though, there shouldn't be much to it (make testready; create coverage_test_egg.pth; cd test; nosetests). That being said, one test still fails:

Yes, I definitely need to improve the docs for developers, you are right.

The py module is due to needing py.test installed to test the py.test plug in, a recent addition to the code base.
