[Buildroot] [PATCH 1/3] support/testing: replace nose2 with pytest - Dockerfile

[Buildroot] [PATCH 1/3] support/testing: replace nose2 with pytest - Dockerfile

[Oguz Ozhan]

From: Oguz Ozhan <oguz.ozhan@mind.com>

- From web page of nose2:
(https://docs.nose2.io/en/latest/)
nose2 vs pytest:
  - pytest is an excellent test framework and we encourage users to consider it for new projects.
  - It has a bigger team of maintainers and a larger community of users.

- pytest is more robust and has more ability compared to nose2

[Buildroot] [PATCH 2/3] support/testing: replace nose2 with pytest - run-tests

[Oguz Ozhan]

From: Oguz Ozhan <oguz.ozhan@mind.com>

- From web page of nose2:
(https://docs.nose2.io/en/latest/)
nose2 vs pytest:
  - pytest is an excellent test framework and we encourage users to consider it for new projects.
  - It has a bigger team of maintainers and a larger community of users.

- pytest is more robust and has more ability compared to nose2

- Changes in this patch:
  - run-tests modified to use pytest instead of nose2 to call tests. A corresponding Collector class added for pytest to list the available tests
  - nose2 plugins removed which are not required anymore
  - in test_iso9660.py, local test_ routine names changed to not be accepted as test_ cases via pytest

Re: [Buildroot] [PATCH 2/3] support/testing: replace nose2 with pytest - run-tests

[Yann E. MORIN]

Oguz, All,

On 2022-10-21 11:15 +0200, Oguz Ozhan spake thusly:

Please see my comment in patch 1 about providing a rationale for the
switch.

Please fold your commit logs at 72 chars.

> - Changes in this patch:

Don't describe the changes, explain them.

E.g. "nose2 plugins removed which are not required anymore" we can see
they get removed, and since the change is about switching away from
nose2, it is obvious they get removed because they are not used anymore.

>   - in test_iso9660.py, local test_ routine names changed to not be accepted as test_ cases via pytest

This last part should be a patch by itself, coming first in the series,
as it can be applied without doing the conversion yet.

I have only had a cursory look at the changes, they look quite OK.

Be sure to run "make check-flake8", I think I could spot too many lines
at one place...

Regards,
Yann E. MORIN.

Please split the changes to the tests in a new patch (first in the series).
While doing that, please fix flake8 warnings.

Please update the manual, section 'Using the runtime tests framework', in the
same commit that changes run-tests to use pytest.

run-tests -s is broken: it does not show the build and runtime console

The detection of a failed test on GitLab CI is broken, even when tests fail
run-tests returns exit code 0.

[Buildroot] [PATCH 3/3] support/testing: replace nose2 with pytest - CI

[Oguz Ozhan]

From: Oguz Ozhan <oguz.ozhan@mind.com>

- From web page of nose2:
(https://docs.nose2.io/en/latest/)
nose2 vs pytest:
  - pytest is an excellent test framework and we encourage users to consider it for new projects.
  - It has a bigger team of maintainers and a larger community of users.

- pytest is more robust and has more ability compared to nose2

- Changes in this patch:
  - the sed command was fine filtering the tests list with nose2 output but removing all operating on pytest output. With pytest no fine filtering is required to get the test names in correct format.

Hello,

IMO, this change should be merged into patch 2.

This regexp must be adapted, something like this:
          (*-support*)
            pattern="${CI_COMMIT_REF_NAME/--/::}"
            runtimes=( $(./support/testing/run-tests -l 2>&1 \
                         | LC_ALL=C sort \
                         | grep "^${pattern##*-}")

Notice that ':' is not accepted on git branches, so we cannot use this branch
name to run a single test on GitLab CI:
 git push gitlab \
 HEAD:foo-support/testing/tests/package/test_php_lua.py::TestPhpLuaLuajit
so I guess we could use a pattern substitution, for instance:
 git push gitlab \
 HEAD:foo-support/testing/tests/package/test_php_lua.py--TestPhpLuaLuajit
and document it in the manual.

The manual must also be updated.
 docs/manual/contribute.txt: $ git push gitlab HEAD:foo-tests.init.test_busybox
 docs/manual/contribute.txt: $ git push gitlab HEAD:foo-tests.init

Regards,
Ricardo

Oguz, All,

This clearly states "for new projects", but we are not new! ;-)

Why do we need to switch to pytest, and what does that bring us? (see
below too)

> - pytest is more robust and has more ability compared to nose2

You provide robustness and more abilities to advocate for switching to
pytest, however, you do not explain what is currently broken that would
be fixed by the pytest robustness, or what new features from pytest we
could leverage, and how.

Note that I am not opposed to switching, but we need a good rationale
for switching.

This commit should also come after we actually did the switch, i.e. we
should first convert support/testing/ over to pytest, then modify the
dockerfile accordingly, which allows to write a better coomit log.

Also, please organise your commit logs as (first line is the title):

    support/docker: install pytest instead of nose2

    Now that the tuntime test infra has switched to using pytest instead
    of nose2, install the appropriate packages in the Dockerfile for our
    reference build environment.

    Note that pytest-parallel is not available i Debian Bullseye, so we
    install it (and its depenencies) from Pypi instead.

Please, pin the version so that the image is reproducible.

Also, if pytest-parallel has dependencies, explicitly install those at
pinned versions too.

Also note in the commit log that pytest-parallel is not available in
bullseye, so we need to get it from Pypi instead (as in my suggestion).

Re: [Buildroot] [PATCH 1/3] support/testing: replace nose2 with pytest - Dockerfile

[Ricardo Martincoski]

[-- Attachment #1: Type: text/plain, Size: 4435 bytes --]

Hello,

I am not against to switch to pytest.
But I didn't understand clearly yet the use case that motivated this series, in
which nose2 is not good and pytest is better. Could you elaborate?

Also, there are issues to be addressed before merging this series:
- the detection of a failed test on GitLab CI is broken, even tests failing
  return exit code 0, so GitLab infra mark them as PASS, see [1];
- run-tests -s is broken (does not show the build and runtime console);
- support to ask a single runtime test to run on GitLab CI is broken due to a
  regexp that needs to be adapted;
- the manual needs to be updated.

There are also some changes in behavior that would be nice to be highlighted:
- someone willing to find a test in the output of run-tests -l can do:
nose2:  run-tests -l 2>&1 | grep pattern
pytest: run-tests -l | grep pattern
- total number of tests:
nose2:  run-tests -l prints the number of tests at the end "Ran 481 tests"
pytest: run-tests -l does not
- the name of tests change (list)
nose2:  test_run (tests.toolchain.test_external_bootlin.\
        TestExternalToolchainBootlinPowerpc64lepower8GlibcBleedingEdge) ... ok
pytest: support/testing/tests/toolchain/test_external_bootlin.py::\
        TestExternalToolchainBootlinPowerpc64lepower8GlibcBleedingEdge::test_run
- the name of tests change (local run)
nose2:  support/testing/run-tests tests.init.test_busybox \
        tests.package.test_php_lua.TestPhpLuaLuajit
pytest: support/testing/run-tests support/testing/tests/init/test_busybox.py \
        support/testing/tests/package/test_php_lua.py::TestPhpLuaLua
- the name of tests change (gitlab test suite)
nose2:  git push gitlab HEAD:foo-tests.init.test_busybox
        see [2]
pytest: git push gitlab HEAD:foo-support/testing/tests/init/test_busybox.py
        see [3]
- the name of tests change (gitlab test case)
nose2:  git push gitlab HEAD:foo-tests.package.test_php_lua.TestPhpLuaLuajit
        see [4]
pytest: git push gitlab \
        HEAD:foo-support/testing/tests/package/test_php_lua.py--TestPhpLuaLuajit
        see [5]
        NOTICE: the use of '--' is just the first solution that came to mind.
- the name of tests are longer, so in the GitLab CI the display is a bit worse:
nose2:  tests.init.test_busybox.TestInitSystemBusyboxRo
        tests.init.test_busybox.TestInitSystemBusybox...
        tests.init.test_busybox.TestInitSystemBusybox...
        tests.init.test_busybox.TestInitSystemBusybox...
        tests.package.test_php_lua.TestPhpLuaLua

        support/testing/tests/package/test_php_lua.p...
        support/testing/tests/package/test_php_lua.p...
- bash completion for the name of a test suite
nose2:  no completion
        support/testing/run-tests tests.init.test_busybox
pytest: since it uses the path as the begin of test name one can type
        'support/testing/run-tests support/testing' and use bash completion for
        test files names:
        support/testing/run-tests support/testing/tests/init/test_busybox.py
- cache of results
nose2:  no cache
pytest: it creates a .pytest_cache/ with a cache of the results, so we could
        later expose another parameter in run-tests that passes '-lf' to pytest,
        which will re-run only the tests that failed on last run
- verbosity when collecting tests:

Hello Oguz,

Thanks a lot for your patch series. However, all commit logs are empty.
What is the rationale/motivation for the changes in this patch series?
Why is pytest better than nose2? Could you send a new iteration with a
detailed commit log for each commit that explains the motivation for
the change, and also describes the change itself, especially in PATCH
2/3, where test cases see changes. BTW, these changes in test cases
could be done in a separate preparation commit, as they would still
work with nose2 I believe.

Also another concern is that the series is not really bisectable, but
admittedly I'm not sure it's easy to achieve without doing all the
changes in one single patch.

Best regards,

Thomas

Hi Thomas.

Thanks a lot for your comments.

I inserted more information in the commit logs and re-sent the patches.
