Agreed. I've just realized that it was more general question, not especially related to this library. Of course we can introduce additional scripts doing what we want to test. But as a contributor to this library I wouldn't decide to add them just for just my tests, because the rest of the library doesn't use them at all and almost all tests here are not portable. I decided to keep the coding style of the library, and yes, it narrowed my possibilities to answer to this question.
