A simple testing library that works on ruby and mruby. This has been designed to be very modular, you can run different types of suites with different setup/teardown and before/after blocks. You can have as many reporters as you want, these can range from "output to the terminal in a nice way" all the way to "shape the results into an XML or JSON for my CI". The secondary purpose of this testing library is to work with mruby for my game engine Taylor and any project built upon that. I also plan to support quite a few ruby versions as I want the code for this to be very portable. The main feature I don't want to drop is positional AND keyword arguments in definitions, this means anything that matches the Ruby 2.6+ spec should be compatible.
