New Pylint (2.4.3) catches several new 'true problems'. At the same
time, it warns about things that are massively and reasonably
employed in FreeIPA.
list of fixed:
- no-else-continue
- redeclared-assigned-name
- no-else-break
- unnecessary-comprehension
- using-constant-test (false positive)
list of ignored (responsibility of contributors and reviewers):
- import-outside-toplevel

The unit tests execution time within Azure Pipelines(AP) is not
balanced. One test job(Base) takes ~13min, while another(XMLRPC)
~28min. Fortunately, AP supports slicing:
> An agent job can be used to run a suite of tests in parallel. For
example, you can run a large suite of 1000 tests on a single agent.
Or, you can use two agents and run 500 tests on each one in parallel.
To leverage slicing, the tasks in the job should be smart enough to
understand the slice they belong to.
>The step that runs the tests in a job needs to know which test slice
should be run. The variables System.JobPositionInPhase and
System.TotalJobsInPhase can be used for this purpose.
Thus, to support this pytest should know how to split the test suite
into groups(slices). For this, a new internal pytest plugin was added.
About plugin.
- Tests within a slice are grouped by test modules because not all of
the tests within the module are independent from each other.
- Slices are balanced by the number of tests within test module.
- To run some module within its own environment there is a dedicated
slice option (could help with extremely slow tests)
Examples.
- To split `test_cmdline` tests into 2 slices and run the first one:
ipa-run-tests --slices=2 --slice-num=1 test_cmdline
- To split tests into 2 slices, then to move one module out to its own slice
and run the second one:
ipa-run-tests --slices=2 --slice-dedicated=test_cmdline/test_cli.py \
--slice-num=2 test_cmdline

This is a sort of rollback to the pre #93c158b05 state with
several improvements.
For now, the nodeids calculation by ipa-run-tests is not stable,
since it depends on current working directory. Nodeids (tests
addresses) are utilized by the other plugins, for example.
Unfortunately, the `pytest_load_initial_conftests` hook doesn't
correctly work with pytest internal paths, since it is called
after the calculation of rootdir was performed, for example.
Eventually, it's simpler to follow the default convention for
Python test discovery.
There is at least one drawback of new "old" implementation.
The ignore rules don't support globs, because pytest 4.3.0+
has the same facility via `--ignore-glob`:
> Add the `--ignore-glob` parameter to exclude test-modules with
> Unix shell-style wildcards. Add the collect_ignore_glob for
> conftest.py to exclude test-modules with Unix shell-style
> wildcards.
Upon switching to pytest4 it will be possible to utilize this.
Anyway, tests for checking current basic facilities of
ipa-run-tests were added.
