compare memory usage between pytest runs #7

Closed djarecka closed 10 months ago

Feature Request

Perhaps it will be useful if you can compare if tests are not using more memory after new changes.

Thanks! We will consider doing this feature but a workaround today is to check how much memory is using the test and then use the limit marker with the current memory usage. That way if the test is using more memory it will fail.

feels like this could be implemented using the pytest core cache fixture https://docs.pytest.org/en/6.2.x/cache.html#cache

the reporter can mirror the information it already prints to the terminal and cache it as well. Then print a warning if the test still passes, but uses more memory (even without the limit_memory marker?)
