PytestConfigWarning: Unknown config option: testspath Warning occurs when ./runtests.py

[TGoddessana]

When you run runtests in your local environment, you'll see a warning like the one below.
PytestConfigWarning: Unknown config option: testspath

According to the official documentation, testpaths is correct, not testpath.

if this is mistake, i'll create some PR.
