Ticket #31431 requested django implement support coverage for parallel
tests. It was marked as wontfix, citing #4501 where a decision was made to
document how to run coverage rather than integrate it.
Unfortunately, the
[https://docs.djangoproject.com/en/dev/topics/testing/advanced/ coverage
documentation] does not mention parallel tests at all.
Since parallel tests use subprocesses,
[https://coverage.readthedocs.io/en/6.0.2/subprocess.html special setup]
is needed for coverage to be accurate. I have so far been unable to figure
this out, and the best information I've found is in this
[https://stackoverflow.com/a/42862546/502816 StackOverflow post].
The coverage section needs documentation covering parallel tests, and the
parallel tests section should probably mention that coverage needs special
setup and link to it.
I would be happy to update the documentation if someone can provide me
with the working answer.
