Logging in subtests is not displayed unless the parent test fails

[rhoban13]

Logging in subtests is not displayed unless the parent test fails. Contrast with stdout is displayed for just the failing subtest.

Minimal example:

import logging


def test_logging_in_subtests(subtests):
    logging.info("before")

    with subtests.test("sub1"):
        print("sub1 stdout")
        logging.info("sub1 logging")

    with subtests.test("sub2"):
        print("sub2 stdout")
        logging.info("sub2 logging")
        assert False

Running python3.8 -m pytest test_pytest.py --log-level=INFO stdout is output but not logs

...
------------------------------------------------------------------------------------------------- Captured stdout call --------------------------------------------------------------------------------------------------
sub2 stdout
================================================================================================ short test summary info ================================================================================================
SUBFAIL test_pytest.py::test_logging_in_subtests - assert False

If instead the parent test fails, logs are output from both failing & succeeding subtests. For example

import logging


def test_logging_in_subtests(subtests):
    logging.info("before")

    with subtests.test("sub1"):
        print("sub1 stdout")
        logging.info("sub1 logging")

    with subtests.test("sub2"):
        print("sub2 stdout")
        logging.info("sub2 logging")
        assert False

    assert False

$ python3.8 -m pytest test_pytest.py --log-level=INFO now produces

------------------------------------------------------------------------------------------------- Captured stdout call --------------------------------------------------------------------------------------------------
sub2 stdout
_______________________________________________________________________________________________ test_logging_in_subtests ________________________________________________________________________________________________

================================================================================================ short test summary info ================================================================================================
SUBFAIL test_pytest.py::test_logging_in_subtests - assert False
FAILED test_pytest.py::test_logging_in_subtests - assert False

Can/should logging be displayed with a per subtest granularity similar to stdout?
