Minitest 6: test feistier! by Ryan Davis Minitest 5 ships with ruby and is the standard test framework for rails. It already provides a traditional unit test framework, spec DSL, mocks, stubs, test randomization, parallelization, machine agnostic benchmarking, and tons of assertions all in under 2kloc.

Come see how you can massively speed up your rails test runs and improve your testing practices by upgrading your test framework.
