Yes, I meant "more choices that are popular" - of those libraries JUnit is the obvious default choice that most people use, unlike in C# where you have NUnit, xUnit and MSTest all enjoying comparable popularity (to each other). My point is that the Python situation, with two popular choices, is hardly "an eclectic mess". Although strictly speaking it might be true that two choices is twice as eclectically messy as one choice, it's still fewer choices and thus less of a mess than C#'s three choices (and I haven't heard anyone calling that a mess).
