I'm discovering a lib availaible on github. I'm interested by functions defined in its unit-tests because I don't find any example elsewhere how to use the lib. I understand it is not primary goal of these functions to be usable by end-user. But, I would like to know if there is a way to use them cleanly if possible rather than copy-paste snippets. If it is only a bad practice, how do you proceed in a similar case?
