Minitest is the default testing framework bundled with Ruby and Rails, offering a lightweight and fast way to write unit, integration, and system tests.
It has minimal configuration requirements, making it ideal for teams that prefer simplicity and convention over customisation. Minitest supports Rails 6, 7 and 8 with Ruby 3+, and is well documented within Rails guides.
Its strengths are speed, small footprint, and zero dependencies, while its weaknesses are fewer expressive matchers and less ecosystem support compared to RSpec.
