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/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 (and stub) +object framework. + +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/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. + + "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.
