Trying to rerun the tests that failed but it just says that the module doesn't exist. I am running the exact command line mentioned in the readme file:

$ make test TESTOPTS="-v test_that_failed"
running build
running build_ext

The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
atexit                pwd                   time
