Minitest 2.1.0 Released

minitest version 2.1.0 has been released!

minitest provides a complete suite of testing facilities supporting
TDD, BDD, mocking, and benchmarking.

minitest/unit is a small and incredibly fast unit testing framework.
It provides a rich set of assertions to make your tests clean and

minitest/spec is a functionally complete spec engine. It hooks onto
minitest/unit and seamlessly bridges test assertions over to spec

minitest/benchmark is an awesome way to assert the performance of your
algorithms in a repeatable manner. Now you can assert that your newb
co-worker doesn’t replace your linear algorithm with an exponential

minitest/mock by Steven B., is a beautifully tiny mock object

minitest/pride shows pride in testing and adds coloring to your test

minitest/unit is meant to have a clean implementation for language
implementors that need a minimal set of methods to bootstrap a working
test suite. For example, there is no magic involved for test-case
