Test & Code

pytest-repeat is a pretty cool plugin to allow you to repeat tests, but currently has an issue with Python 3.14. pytest-repeat is a fun little plugin that allows you to repeat tests. There are a couple ways you can repeat tests. You can pass in a command line parameter called count. So dash dash count equals 10, for instance, will repeat your tests 10 times. Or you can, and that will just repeat all the tests you give it on the command line. Or you can take an individual test and put a repeat marker. So you could say like `@pytest.mark.repeat(3)` and give it the number of times you want a test to repeat if it's just one test. Now, if you want to do a whole file, for instance, by default, it will repeat each test at a time. So let's say if you repeat three, it'll test the first test three times and then go on to the next test. And if that's not exactly what you want, if you want to go through the entire session and then start over, you can give it a session scope. So there's a repeat scope that you can pass it. So you've got count and repeat scope. Let's say I just wanted to run my entire test suite over and over again until it failed. You could give it a count of 1,000 with a repeat scope of session and also the dash x flag for stop on fail. And it'll just keep running and try to do it 1,000 times, but stop as soon as the failure occurs. Super useful, kind of fun for debugging.

However, I wanted to try, it looks like it's been tested against 3.12. I wanted to try it against both Python 3.13 and Python 3.14 today just to make sure that things are working fine. There's no reason why it shouldn't work because it's just, if I look at the code, pytest-repeat, the source code, just using fairly standard pytest stuff. It uses `pytest_generate_tests` to generate the repeat numbers. Pretty cool way to do that. Anyway, so I went ahead and tried it on Python 3.13, no problems, and then Python 3.14, and it didn't work. And I can't actually figure out why. I thought maybe there was something in my setup, so I modified the tox, just cloned the repo, modified the tox in and added 3.14 there, and tried that. Tried it with tox, And still, this is failing, and I can't figure out why. So for some reason, with Python 3.14, you can't repeat tests. I'll keep looking into it. There is no rational reason why this should not work, but I can't get Python 3.14 to repeat. That's all for now. Now go out and test something. But just test it once. You can't repeat it.
