I appreciate your willingness to write tests, but please don't spend
too much effort on testing NULL inputs, it's not an interesting case
unless there's a specific app that depends on it. Otherwise we end up
adding NULL checks all over the place for no good reason. It's much
more interesting to test valid inputs.
