While trying the "pip install" step in the install instructions, the build fails as below.

Hi @minfrin - Unfortunately CalDAVTester requires python 2.7, which is end of life. I can’t say I recommend using python 2 at this point, however it should still work. One silver lining I guess is that because CalDAV tester is a purely over-the-wire test suite, it is totally isolated from whatever server it is testing against.

This project has historically been maintained alongside CalendarServer, which was “archived” some months ago. CalDAVTester may have broader use than CalendarServer did, as it is (as far as I know) the most complete CalDAV conformance test suite. All the same, we would likely rely on community contributions to get this project python3 clean.

A first step towards Python 3 compatibility is proposed in PR #40.
