No prompt running memory profiler against pytest #355
Description
I'm trying to run memory_profiler against pytest but no prompt or logging is shown (while it does record a dat file for the plot).
I tried:
python -m memory_profiler pytest
mprof run pytest
mprof run python -m pytest
pytest
with @profile, with pytest -s to avoid prompt capture or
fp = open('memory_profiler.log', 'w+')
@profile(stream=fp)
I added the decorator, either in a single test or in a function being used by that single test.
Relevant information:
- python 3.8.9
- pytest 6.2.5
- memory-profile 0.60.0
- inside a virtualenv
Any suggestions?
Thanks for any help

OH, IT WORKS!
To test a single test:
Add
from memory_profiler import profileto your test file, and@profileto your to-test function.Then you can use this to test this one file and get output:
Can't share code because it's proprietary, but here's the output:
python -m memory_profiler pytest -sk test_my_codeBTW,
mprof run pytestcreates a.datfile, andmprof plot --output file.pngactually generates a file you can view. You can also use.svginstead of.png
