Tired of reinventing the wheel for container testing? See how the #pytest_container plugin simplifies testing #containers with #Python in this #oSC25 talk! No more plumbing; just define, connect, #test and go. #pytest #DevOps #openSUSE https://youtu.be/kU9NS1FpfY8?si=qyjoR5zfMWI7qpY3
une bibliothèque pour mocker les ressources #AWS utilisées dans le code de production #Python que vous testez (S3, par exemple) : https://github.com/getmoto/moto
La page https://github.com/getmoto/moto/blob/master/docs/docs/getting_started.rst documente comment écrire les tests (#pytest, #unittest) et donne quelques conseils pour écrire du code de production plus facile à tester (en ce qui concerne les interactions avec boto3, le client vers les services AWS).
That won't work. It says so in the docs:
> pyfakefs will not work with Python libraries that use C libraries to access the file system.
Which is what numpy is doing.
@encthenet @rachelplusplus Dunno if you've considered this, or would consider it, but pytest has a plugin, pytest-fakefs (https://github.com/pytest-dev/pyfakefs), that implements an in-memory filesystem complete with file objects that you can use to test file handling code without having to put things on disk. IMO the plugin ecosystem for handling things like this is one of pytest's biggest advantages over unittest.
Or if you prefer, pytest also has built-in functionality that makes working with temporary files pretty easy.

Idle thought apropos of nothing specific:
The very same folks telling me BOTH that I MUST use pytest, and that Django MUST have its JSON API story built-in continues to be ironic.
I'd (probably) at least open with the thought that testing is easily as central to a language as JSON APIs are to a web framework.
I don't see a movement to merge pytest to the stdlib.

Isn't it awesome that a test failure in #Twisted (which probably indicates a real problem with the code) occurs only if you have additionally installed #Trio, #PyTest and Py? Like, my understanding is that Trio gets imported by Twisted, and via automagic optional import chain Trio → PyTest → Py, a bug gets triggered.

I'm adding resources for future reading for mine and Marie's #Python #packaging tutorial for #PyConUS, and I realised that I don't know any good #pytest tutorials for beginners. Does anyone have any reccommendations?
@gagliardi_vale The #pytest documentation is also pretty decent, come to think of it: https://docs.pytest.org/en/stable/
Decentralizers, attention! :)
Last #deltachat releases introduced stable #p2p group membership not found in any other messenger. Members can add/remove peers also while being offline, and when everything comes online again, everyone has the same consistent membership view. We formalized and ran a simulation model using #TLA+ (invented by Leslie Lamport of vector clock fame):
https://github.com/chatmail/models/tree/main/group-membership
and a complementary #pytest model with more corner cases tested here:

Dear @ThePSF ...
having been engaged with #Python through co-creating #pytest #pypy, giving talks and trainings i appreciate that the PSF has long been a champion of diversity and inclusion! Are you aware that these days many non-USians are canceling their US travels? The German foreign ministry warns about travel to the US if you are pregnant or don't have your passport carrying a birth gender marker, then this: https://www.kpbs.org/news/border-immigration/2025/02/28/german-tourist-held-indefinitely-in-san-diego-area-immigrant-detention-facility
Maybe better update the #Pycon webpage accordingly?
@WillyECoyote69 Definitely pytest, if you ask me. pytest is by far my favorite testing framework out of all the ones I've used across different programming languages.
Unless using things outside the standard library is a huge burden for you, of course, but that's rarely the case.
Hey, #python / #django people: I dimly recall a tool that uses #coverage data to only run #pytest tests that impact changed lines of code, or changed methods/logical blocks of code.
Like: "User.get_display_name was changed, and coverage data shows that these 15 tests test this method directly or indirectly, so only run those"
ring any bells? I found partialtesting (dead) and pytest-watch (spams *such* an amount of irrelevant messages in my project it's unusable, see https://github.com/joeyespo/pytest-watch/issues/115)
Oh, and taking inspiration from #pytest, I added colour to #unittest output in this one

Some nice #pytest techniques here as @brianokken updates my "Testing some tidbits" post: https://pythontest.com/pytest/testing-tidbits-pytest/
Anybody got recs for good introductory resources on writing tests in Python? Not just stuff like pytest syntax and whatnot, but actual good practices, thorough overview of commonly accepted testing principles, and some real life examples?
