Closed desilinguist closed 1 year ago

desilinguist commented 1 year ago

Update all tests to be nose2-compatible.
Update pre-commit config to ignore docstyle and flake8 errors in test files.
Replace nose with nose2 in requirements file.
Update Gitlab and Azure CI builds to use nose2.
Add unittest.cfg for nose2 configuration
Move testing utilities into new skll.utils.testing module since nose2 doesn't pick up the tests directory as a module.
Update all tests to use skll.utils.testing.
Update .coveragerc with proper exclusions.
Disable logging in very noisy test file.

There are still references to nosetests in CONTRIBUTING.md. Also it is said there that python=3.10 is required for setting up a development environment. Maybe that's still true for other reasons, but I think it should be considered. I actually set up an environment that uses 3.11 and I think the unit tests are running fine with nose2.

Good catch on CONTRIBUTING.md. As for Python 3.11, there's a separate issue #744 for that which I will work on after this one is merged. As part of that, I will also be switching the Azure build to 3.11 from 3.9.

All unit tests passed with 3.11.
