Will run all tests which are decorated with the @pytest.mark.slow decorator. platform win32 — Python 3.8.1, pytest-5.4.3, py-1.9.0, pluggy-0.13.1 can't reproduce the performance increase. By voting up you can indicate which examples are most useful and appropriate. Run tests from packages. I've tried old pytest versions with Python 3.7 and 3.8. Looking narrowly at how _matchfactories can be made faster, I am unsure about something. …. The text was updated successfully, but these errors were encountered: I think a cache there wouldn't hurt (might even use @lru_cache(maxsize=None) instead), but I think it would be worth to investigate this a little further to see if we can have more gains. Sometimes we want a test to fail. We register the markers 'slow' and 'crazy', which we will use in the following example: [pytest] markers = slow: mark a test as a 'slow' (slowly) running test … For more information see marks. That looks wrong to me, but cannot really say for sure. Sure, let me generate and obfuscate the report. rootdir: D:\Python @rndusr Hopefully this should get CI working again with current pytest pytest.ini was missing from MANIFEST.in, so I have added it here @pytest.mark.wip, — Docs: https://docs.pytest.org/en/latest/warnings.html Last I looked it hadn't been fixed at least. @atzorvas Instead of using -m pytest, you can provide the full path to the pytest script. pytest --pyargs pkg.testing. These tests can be identified with the pytest annotation @pytest.mark.slow. A copy of a testpage pdf is placed in the requested output dir, so a valid Pdf is available. A test function should normally use the pytest.mark.django_db mark with transaction=True. It takes between 3 Anyway, when pytest starts to slow down, logging messages coming from logging library, as well as the stacktrace at the end of pytest execution, start to slow down, like if there's something in the terminal plugin trying to access data or to write/read somewhere. @Nepherhotep To get a better understanding, it will help to get a profile of the collection phase on your test suite. To skip these tests, execute pytest-m 'not slow'. If you now try to use a marker that is not registered (like sloooow) , pytest will immediately inform you about your mistake and name the file in which you used the wrong marker: ===================== test session starts ====================== ***> wrote: Tests collection is slow on high number of tests, diff --git a/src/_pytest/nodes.py b/src/_pytest/nodes.py. @rndusr JFI: ce1cc3d seems to have quite an impact, but is in 3.10 already (so likely not relevant) - what version have you've been using before this got fixed for you? pytest --pyargs pkg.testing. We register the markers 'slow' and 'crazy', which we will use in the following example: [pytest] markers = slow: mark a test as a 'slow' (slowly) running test … test_lookup_should_not_throw_error_when_key_missing, The Mikado Method: A Great Help to Work With Legacy Code, Allowing Self-Signed Certificates on Localhost with Chrome and Firefox, How to Activate TLS 1.2 on Windows Server 2008 R2 and IIS 7.5, How to Disable TLS 1.0, 1.1 and SSL on Your Windows Server, Using Logstash to Analyse IIS Log Files with Kibana, Python Friday #51: Parametrised Tests With Pytest, Python Friday #50: Speed up Pytest With Markers, Python Friday #49: Creating Your Own Fixtures for Pytest. …. I've tried old pytest versions with Python 3.7 and 3.8. pytest-attrib. ‘sloooow’ not found in markers configuration option @rndusr I tested the most recent version in pypi, and it's still around 2 minutes for 25k tests. Is the following expected behavior? However, collection time still seem to asymptotically depend on the number of tests, as the first 5k are collected just for 15 seconds. _____________ ERROR collecting test_own_fixture.py _____________ As for cache, if I want it to be in 4.6-maintenance branch as well, do I need to submit two different PRs - lru_cache for "master" and dict-based cache to "4.6-maintenance" (as lru_cache is not supported by 2.7 yet)? # content of pytest.ini [pytest] markers = webtest: mark a test as a webtest. ( --collect-only オプションを使用すると、実験がスピードアップされます). rootdir: D:\Python pytest -m slow. The pytest-attrib plugin extends py.test with the ability to select tests based on a criteria rather than just the filename or pytest.marks. No idea what's going on here. PyCharm supports test parametrization implemented in pytest through @pytest.mark.parametrize. Evaluation happens within the module global context. This knowledge of markers allows us to run a specific subset of our tests and get faster feedback. You signed in with another tab or window. wrote: This comment has been minimized. To exclusively test the slow tests, execute pytest-m slow. My favorite documentation is objective-based: I’m trying to achieve X objective, here are some examples of how library Y can help. plugins: cov-2.10.1, html-2.1.1, metadata-1.10.0 slow: mark test as slow. To create a wip marker, we can add @pytest.mark.wip to our test: We now can run all tests that have this wip marker by calling pytest with an option -m “wip” (or -m “not wip” to run everything except wip): ===================== test session starts ====================== This knowledge of markers allows us to run a specific subset of our tests and get faster feedback. pytest -m slow. Thanks for your effort btw! !!!!!!!!!!!!!!!!! (But they are mostly parametrized. Fast and slow tests using pytest. Apparently, tests collection in pytest is way slower than in nosetests - 130s vs 30s. @pytest.fixture(scope="function", autouse=True) def pdftools_popen_mock(request): """ Mocks away the Popen calls to pdflatex in tools.pdf_exports. python3 -m pytest runs tests (they are in the tests subdirectory). rootdir: D:\Python, inifile: pytest.ini Note that via tox this will need to be -- --runslow closes #70 It is a good practice to add the reason parameter with an explanation why this test is skipped: If we nor run our tests, the skipped tests get an s instead of a . If both those conditions are satisfied the pytest.skip function is run, which skips the current test adding the specified string as … Integration tests are run after normal tests (unit tests) and slow integration tests are run after (quick) integration tests. This knowledge of markers allows us to run a specific subset of our tests and get faster feedback. I don't use slow marker and have to add it to run my test even though it's just for panda. Successfully merging a pull request may close this issue. This commit was created on GitHub.com and signed with a. I'd like to bisect, but I'm having trouble installing pytest. wrote: Thanks a lot! Plugin for pytest to mark tests as integration or slow integration. With pytest, one can mark tests using a decorator. We’ll occasionally send you account related emails. Don't run snpEff as this step may fail on low-memory machines, such as laptops. seconds (20k tests). Notify me of follow-up comments by email. Next week I explain the parametrize marker that can help us to write less tests. This site uses Akismet to reduce spam. PyBerlin is a new meetup community in Berlin, Germany that strives to be open and inclusive, with talks from a broad range of topics for anyone who is interested in Python. Let us create a set of speed values to test car.accelerate and car.brake functions: speed_data = {45, 50, 55, 100} Modify the test code to the following: Going deeper into _matchfactories method, I was able to reduce collection time from 130s to 85s just by caching the results of _splitnode method: It doesn't solve the asymptotic problem, but just making _splitnode and thus _matchfactories method faster: Please let me know if you think there could be a better way to fix the problem. That's the result of tests collection, when splitnode optimization PR is merged. Note that as usual for other command-line applications, in case of conflicting options the last one wins, so the example above will show verbose output because -v overwrites -q. The pytest.mark plugin already provides a featrure to mark tests and run only the marked tests. They should not be mixed. *, 5.3. Sounds like it. Doesn't matter if I use Python 3.7 or 3.8. If you can arrange a reproduction for this, I think it will be helpful. Have a question about this project? @pytest.mark.slow def some_slow_test(): pass Then, from the command line, one can tell pytest to skip the tests marked "slow" pytest -k-slow If I have an additional tag: @pytest.mark.long def some_long_test() pass I would like to be able to skip both long AND slow tests. complete stack trace : (instead of / additional to #5681 - but likely makes not much sense given different inputs there; i.e. Save my name, email, and website in this browser for the next time I comment. We can mark such tests with the pytest.mark.xfail decorator: Pytest reports tests that we expect to fail with an x: ===================== test session starts ====================== Sign in So if the user executes in the command-line: pytest -m slow. If a (quick) integration tests fails, slow integration tests are not run. A simple way to solve this problem is to register your markers with pytest. platform win32 — Python 3.8.1, pytest-5.4.3, py-1.9.0, pluggy-0.13.1 For me, test collection went down from more than a minute to about 6 seconds. This in only half of the benefits you get. Example: skip(reason=”no way of currently testing this”) skips the test. If a unit test fails, (quick) integration and slow integration tests are not run. From looking at the release dates, the fix (for me) was probably introduced in 5.4.0. @Nepherhotep how did the changes that went into pytest already affect your use case? In my example pytest found 12 test and skipped 11 tests because they did not have the wip marker. To run a specific test within a module: pytest test_mod.py::test_func Another example specifying a test method in the command line: pytest test_mod.py::TestClass::test_method Run tests by marker expressions pytest -m slow Will run all tests which are decorated with the @pytest.mark.slow decorator. Sign in to view. @pytest.mark.wip: Tests for features we currently work on, @pytest.mark.slow: Mark slow tests to ignore them for development … Next. Yes, this is a good idea. I've been trying to get the slow test collection back, but I can't! The strict parameter makes sure that our test suite fails should by any reason the test start to pass. ***> wrote: Tested our case, without the fix - it's 1m 33 seconds, with the fix - 1m 29 The flexibility of creating markers on the fly has a big downside when you work in a team: You do not know which markers exist and how you write them. >. Example: skipif(‘sys.platform == “win32″‘) skips the test if we are on the win32 platform. Enter your email address to subscribe to this blog and receive notifications of new posts by email. The reporter can collect all independent tests in one report (say you use jenkins and need a junit style xml). Thanks for getting back. A helpful marker is skip, that allows us to ignore a test. @pytest.mark.slow def test_variation_workflow(): """Test variation.workflow. Have you considered what @bluetech suggested? I don't It would be interesting if you could git-bisect it. That curve is classic accidentally quadratic performance, which might help to diagnose it , @Nepherhotep collected 9 items / 1 error / 8 selected, ======================== ERRORS ============================ platform win32 — Python 3.8.1, pytest-5.4.3, py-1.9.0, pluggy-0.13.1 Importing panda make my pytest tests fail because of one marker "slow" is required in /usr/local/lib/python2.7/dist-packages/pandas/util/testing.py:55: in slow = pytest.mark.slow. plugins: cov-2.10.1, html-2.1.1, metadata-1.10.0 platform win32 — Python 3.8.1, pytest-5.4.3, py-1.9.0, pluggy-0.13.1 pytest --pyargs pkg.testing This will import pkg.testing and use its filesystem location to find and run tests from. ========= 1 passed, 11 deselected, 1 warning in 0.09s ==========. #7130 fixes at least one instance of quadratic behavior in relation to the number of tests, so might help here.
