I read the patch. It looks good.

Anyway, I have two questions:

1. I saw 3 variants of writing description for skipping test descriptor:

requires os.mkfifo

test needs socket.inet_pton()

needs os.read

Which one is the preferred way to go? "requires" or "test needs" or "needs"? Or it does not matter?

2. I saw 2 variants of writing the function name required for running the test.

test needs socket.inet_pton()

test needs socket.inet_pton

Which one is the preferred way to go? With or without parentheses? Or it does not matter?
