With new Pytest 6.0 [0]:
> PytestDeprecationWarning are now errors by default.
Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type PytestDeprecationWarning now generate errors
instead of warning messages.
PytestWarnings are no longer marked as the part of public API, but as
internal warnings. It's unsafe to use bare PytestDeprecationWarning,
which is turned into the error on major releases.

Currently, such arguments are eaten by 'ipa-run-tests' script as they
are not quoted.
For example, running ipa-run-tests -k ''
results in the actual invocation would be like as:
['/bin/sh',
'--norc',
'--noprofile',
'-c',
'--',
"/usr/bin/python3 -c 'import sys,pytest;sys.exit(pytest.main())' -o "
'cache_dir=/tmp/pytest-of-root/pytest-12/test_ipa_run_tests_empty_expression0/.pytest_cache '
'--confcutdir=/usr/lib64/python3/site-packages/ipatests -k ']
Note: expressions or marks could be empty as a result of the building
of command line args by more high-level tools, scripts, etc.
So, a short-termed solution is the quotting of zero-length arguments.

This Pytest plugin is intended to issue warnings on collecting
tests, which employ unittest/nose frameworks or xunit style.
For example, this may look like:
"""
test_a/test_xunit.py:25
test_a/test_xunit.py:25: PytestDeprecationWarning: xunit style is deprecated
def test_foo_bar(self):
test_b/test_unittest.py:7
test_b/test_unittest.py:7: PytestDeprecationWarning: unittest is deprecated
def test_foo_bar(self):
"""
To treat these warnings as errors it's enough to run Pytest with:
-W error:'xunit style is deprecated':pytest.PytestDeprecationWarning

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.
