- Some tests can not work at rpmbuild time, because we can not run
rpmbuild in rpmbuild, and there's no .git/ directory, skip.
- Use 'titodir' below 'srcdir', to not pollute the /tmp/tito dir.
- The test_colors() test requires color-friendly TERM env.
- EL7 is EOL, do not enable tests there.
- Requires us to add pytest.ini to tell pytest where to look for test
files, and set the python path.
- Mock drops terminal from the tested code, so we have to "mock" it in
test_colors()
- Enable coverage in tox tests.
Fix#358
Previously the bugzilla-specific code was implemented in `tito.common`
which is imported from everywhere. Therefore missing dependency
to `python3-bugzilla` resulted in failure even for simple commands
such as `tito build --tgz`.
These tests began failing after a correction to another test. The
other test had been patching the error_out function without unpatching
it and thus polluted the test environment.
Also reset to a known directory at the beginning of the common tests so
that we don't start in a directory that has since been unlinked.
