Questions tagged [minitest]

a testing framework that comes in the standard library of Ruby 1.9.

Minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. When making assertions in Cucumber step definitions, there are a few different libraries you could choose. MiniTest is one of the candidates.

MiniTest’s assertions are built into Ruby, which makes them a handy tool to reach for. They use a style of assertion that you’ll be familiar with if you’re used to making assertions in any xUnit testing framework.
