Oh sorry I don't think I was clear: this test you should keep, I meant to remove the test you have added before (test_help_and_version_verbose_after_argument_error).

This test (and the adjustment you made to it) is necessary: when we get a parser error, we need to ensure we still display at least the pytest version.

I asked you to remove the "verbose" kind of this same test because the output should actually be the same as the "non-verbose" kind: "--verbose --verbose" output normally includes plugins, which are not loaded when a parser error happens anyway, so we regardless fall back to the "non-verbose version" information.

IOW: please revert your dfcec18 commit and just delete test_help_and_version_verbose_after_argument_error, leaving test_help_and_version_after_argument_error as is. 👍

Thanks!

Hey there--so I checked this today and realized that I accidentally deleted the original test test_help_and_version_after_argument_error while trying to delete onlytest_help_and_version_verbose_after_argument_error.

I'm really sorry for that confusing mistake, but I've pushed another commit to correct it.
