## What it is
Minitest is a small, fast, and readable testing suite for Ruby supporting TDD, BDD, spec-style expectations, and benchmarking. It ships as minitest/test, minitest/spec, minitest/benchmark, and minitest/pride with a rich set of assertions.

## Use cases
- write unit tests for ruby code
- run tdd workflow in ruby
- bdd-style specs with expectations
- assert algorithm performance with benchmarks
- replace rspec with a lighter test framework
- bootstrap a minimal test suite for a language implementation

## When to choose
- you want a fast, dependency-light ruby test framework
- you prefer plain ruby over a testing DSL
- you need both test-unit and spec styles in one gem
- you want to assert performance characteristics of algorithms

## When to avoid
- you need rspec's rich matcher DSL and ecosystem
- you need built-in fixtures like database transactional tests
- you want extensive mocking out of the box

## Facets
- artifact type: library
- maturity: stable
- function: testing, benchmarking, e2e-testing
- domain: testing, developer-tools, programming-languages
- platform: ruby, cli
- tags: tdd, bdd, unit-testing, spec, test-framework, ruby-gem
