The number of lines of code being 155 lines is not an excuse to have zero tests, especially in an SDK and it doesn't mean it works.

It only means you know it 'works' on your machine and it may not work on someone else's or in another scenario.

Well, you've just proven my point.

The tests should be written first before you write the actual code and to just write them after the fact defeats the entire purpose of knowing what to test for and then assuming that it 'works'.
