> If you want to thoroughly a regex, just test the regex by throwing a dozen strings at it. Don't bootstrap the program and construct valid input requests to test each of those strings (but do do that to test that everything can work together, which includes a subset of those strings). Or even write the test cases separately, then import them into a unit test runner that can check them all very fast as well as an integration test runner that can check them all very slowly.
