Yeah, running tests is kind of not ideal right now because coverage hard-codes the file paths for the coverage file that we use as a fixture in tests. If you want to run tests, you would need to make sure to copy the package to /home/johannes/workspace/ocular.py-dev.

To make the tests really portable, we would probably need to generate this file before running tests which would add another unknown though. Not sure if there is a better way.

[michaeljoseph]

We could generate the file in a well-defined location (like ~/.coverage, or /tmp/ocular-coverage) and then move the coverage file there in the test setup?

[schmittjoh]

Yeah, sounds good. Would you like to give this a try?

Sure, what tests do you use to generate that test coverage file?

[schmittjoh]

Right now, this is from the main project. It would probably make sense to embed a small test project through to add more stability when generating it.
