utils/test/test-aa-notify.py:
Change `AANotifyTest.test_entries_since_login()` to be decorated by a
`skipUnless()` checking for existence of **/var/log/wtmp** (similar to
`AANotifyTest.test_entries_since_login_verbose()`).
The test otherwise fails trying to access /var/log/wtmp in environments
where the file is not available.
Fixes#120
- Code layout based on aa-genprof example
- Extend Python dependencies to cover new need by aa-notify
- Update documentation after aa-notify is no longer in Perl
When run locally on a development machine or in production, the full test
is likely to run. However inside a CI system container 'last' might fail
to show last login or there might not be access to kern.log and the test
will automatically skip those without failing the whole test suite.
This will help ensure the future rewrite of aa-notify from Perl to Python
is less likely to introduce regressions. Tests run the command line utility
via a subprocess so it does not matter that the tests are in Python but
the aa-notify utility is in Perl (for now).
