Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I haven't read everything carefully yet, but this is what catches my eye first

While mocking seems fine, I feel that we're just checking how the test function is being called, but we're not testing whether it works or not.

@picnixz Thanks for your review! I use mock instead of testing the whole server because starting a real HTTP server would take much more time. Also, the result might be influenced by other applications and processes. We can assume that the server will work normally if we call the test function correctly because we have already tested the test function in the ScriptTestCase class. Should we add more test cases without mock to see if the server can be started and run normally?

IIRC, there are tests that use real servers (but correct me if I'm wrong), and we have a helper for finding the next available port in case. I don't think the tests will take long. It's just about serving files over HTTPS. However, just check that we're indeed covering everything in ScriptTestCase.
