tests: add a test runner utility that prints nothing when all tests pass This will be used to run tests through run-tests, which will expect no output for a unit test that passes successfully. The motivation for using unit tests instead of the current Python tests is that they don't require an output file for comparison and that they're easier to write because of the available tools from unittest (setup, asserts).
