	   slow, thorough
	       run slow tests, or repeat non-deterministic tests more often

	   quick
	       do not run slow or performance tests, or do extra repeats of non-deterministic tests (default)

	   undefined
	       run test cases that deliberately provoke checks or assertion failures, if implemented (default)

	   no-undefined
	       do not run test cases that deliberately provoke checks or assertion failures

       -p=TESTPATH
	   only run test cases matching TESTPATH

       -s=TESTPATH
	   skip test cases matching TESTPATH

       --seed=SEEDSTRING
	   run all test cases with random number seed SEEDSTRING

       -o=LOGFILE
	   write the test log to LOGFILE

       -q, --quiet
	   suppress per test binary output
