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.

i18n-tasks helps you find and manage missing and unused translations. It analyses code statically for key usages, such as `I18n.t('some.key')`, in order to report keys that are missing or unused, pre-fill missing keys (optionally from Google Translate), and remove unused keys.

IDE tools for code completion, inline documentation, and static analysis

An opinionated language server for Ruby

Sets package level boundaries between a specified set of ruby constants to minimize cross-boundary referencing and dependency.

Flay analyzes code for structural similarities. Differences in literal values, variable, class, method names, whitespace, programming style, braces vs do/end, etc are all ignored. Making this totally rad.

Flog reports the most tortured code in an easy to read pain report. The higher the score, the more pain the code is in.

RSpec::Parameterized supports simple parameterized test syntax in rspec.

Useful tools for Sorbet enthusiasts.

TypeProf performs a type analysis of non-annotated Ruby code. It abstractly executes input Ruby code in a level of types instead of values, gathers what types are passed to and returned by methods, and prints the analysis result in RBS format, a standard type description format for Ruby 3.0.

RBI generation framework

Analyze code for potentially uncalled / dead methods, now with auto-removal.

Embed Crystal code directly in Ruby.
