What’s the idea behind pytest-cache?

pytest python testing

pytest-cache It seems to be a tool to cache func/args->result pairs and even persist them between testsuite-runs. Which seems like a great idea to speed things up. However I haven’t noticed any mention of automatically detecting a change of a function source code and invalidating corresponding cache entries.

datetime mocking python testing

Can anyone tell me why this isn’t working? Perhaps someone could suggest a better way? Answer There are a few problems. First of all, the way you’re using mock.patch isn’t quite right.

I come from the Java world, where you can hide variables and functions and then run unit tests against them using reflection. I have used nested functions to hide implementation details of my classes so that only the public API is visible. I am trying to write unit tests against these nested functions to make sure that I don’t break
