minitest provides a complete suite of testing facilities supporting TDD, BDD, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is very readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test 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/test 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/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test 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. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply. == Features/Problems: minitest/autorun - the easy and explicit way to run all your tests. minitest/test - a very fast, simple, and clean test system. minitest/spec - a very fast, simple, and clean spec system. minitest/benchmark - an awesome way to assert your algorithm's performance. minitest/pride - show your pride in testing! minitest/testtask - a full-featured and clean rake task generator. Incredibly small and fast runner, but no bells and whistles. Written by squishy human beings. Software can never be perfect. We will all eventually die.

TZInfo provides access to time zone data and allows times to be converted using time zone rules.

Modern concurrency tools including agents, futures, promises, thread pools, actors, supervisors, and more. Inspired by Erlang, Clojure, Go, JavaScript, actors, and classic concurrency patterns.

A toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Rich support for multibyte strings, internationalization, time zones, and testing.

Docile treats the methods of a given ruby object as a DSL (domain specific language) within a given block. Killer feature: you can also reference methods, instance variables, and local variables from the original (non-DSL) context within the block. Docile releases follow Semantic Versioning as defined at semver.org.
