Remove yield test that are not support by pytest anymore...
Remove yield test that are not support by pytest anymore And remove comparison of str/unicode as it is not relevant anymore as both are the same. We can now unpin pytest as well, which we should make sure is in release notes and in the conda-forge recipe As nose does not understand `@parametrize`, and the nose `@skip` decorator messes with that as well, we mark tests with parametrize as not-tests for iptests
