Currently, only one IPA environment is tested within Docker
containers. This is not efficient because Azure's agent gives
6 GB of physical memory and 13 GB of total memory (Feb 2020),
but limits CPU with 2 cores.
Next examples are for 'master-only' topologies.
Let's assume that only one member of github repo simultaneously
run CI. This allows to get the full strength of Azure.
Concurrency results for TestInstallMaster:
------------------------------------------
| job concurrency | time/jobs |
------------------------------------------
| 5 | 40/5 |
| 4 | 34/4 |
| 3 | 25/3 |
| 2 | 19/2 |
| 1 | 17/1 |
------------------------------------------
Results prove the limitation of 2 cores. So, in case of jobs'
number not exceeds the max capacity for parallel jobs(10) the
proposed method couldn't save time, but it reduces the used
jobs number up to 2 times. In other words, in this case CI
could pass 2 x tests.
But what if CI was triggered by several PRs? or jobs' number is
bigger than 10. For example, there are 20 tests to be run.
Concurrency results for TestInstallMaster and 20 input jobs:
------------------------------------------------------------------
| job concurrency | time | jobs used | jobs free |
------------------------------------------------------------------
| 5 | 40 | 4 | 6 |
| 4 | 34 | 5 | 5 |
| 3 | 25 | 7 | 3 |
| 2 | 19 | 10 | 0 |
| 1 | 34 | 20 | 0 |
------------------------------------------------------------------
So, in this case the optimal concurrency would be 4 since it
allows to run two CIs simultaneously (20 tasks on board) and get
results in 34 minutes for both. In other words, two people could
trigger CI from PR and don't wait for each other.

Docker utilizes its own way to provide DNS (hostname, hosts, NS).
By default, they are almost the same as the host's ones.

::1 localhost ip6-localhost ip6-loopback

As a result FreeIPA uses 168.63.129.16 (AP DNS NS [1]) as a DNS forwarder.
It's not desirable to rely on this.

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.

This can be due to fastestmirror not being used to check
mirror availability and sometimes speed. Combined with a

can lead to download failures that could be avoided.

'taskToRun' specifies a script ipatests/azure/azure-${taskToRun}.sh that

Azure Pipelines provides 10 parallel free runners for open source projects.
Use them to run following jobs:
- Build: build RPMs and Fedora 30 container with them
- Lint: run linting of the source code
- Tox: run py36,pypi,pylint tests using Tox
- Web UI unit tests: run Web UI unit tests with Grunt/QUnit/PhantomJS
- XMLRPC tests: install FreeIPA server and run XMLRPC tests against it
All jobs are running in Fedora 30 containers. Build, Lint, Tox, and Web
UI unit tests run inside f30/fedora-toolbox container. Build job
generates a container with pre-installed FreeIPA packages using official
fedora:30 container. All containers are picked up from
registry.fedoraproject.org.
Artifacts from the build job are pushed to a pipeline storage and reused
in the XMLRPC tests. They also are accessible in the 'Summary' tab to
download.
XUnit and QUnit outputs from the tests that produce it are reported in
the 'Tests' tab.
Logs from individual steps from each job are available for review in
the 'Logs' tab. They also can be downloaded.
