    Python trace module does not display calling relationships when running pytest - Stack Overflow

    programmeradmin3浏览0评论

    I would like to track the functions invoked by pytest test cases. I use this test file in xarray as an example. I use the following command to trace

    python -m trace --trackcalls --module pytest -rA xarray/tests/test_coding.py -n 64

    In the output I am able to see test cases are successfully executed.

    But in the following calling relationships, none of the test methods and the methods that are supposed to be invoked are included. I would like to know why and how to resolve this issue. Thanks.

    Reset to default 0

    pytest sometimes runs tests in subprocesses (especially with certain plugins like pytest-xdist for parallel test execution). The trace module typically doesn't capture calls in subprocesses because it's designed to trace the main process.

    Solution: Run pytest without parallelism (pytest -n 1), so the tests run in the main process.
