Description:

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 readable. minitest/spec is a
functionally complete spec engine. It hooks onto minitest/unit and
seamlessly bridges test assertions over to spec expectations.
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
one. minitest/mock by Steven Baker, is a beautifully tiny mock object
framework. minitest/pride shows pride in testing and adds coloring to your
test output. 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
discovery.
