I did this

Thanks for the report. The check on a suitable httpd for the pytests was not very helpful so far. I added #10883 to improve this and the error messages it gives.

Generally, I would not advise to run sudo pytest. It is not necessary.

Note that the pytest suite looks for three commands httpd, apachectl and apxs. You seem to be on macOS, which provides the first two, but not apxs. On Linux distributions, apxs is installed via the apache2-dev package. On macOS, I am not sure if homebrew or other package managers do that.

It would be nice to hear if #10883 improves the situation for you.
