Minitest vs. RSpec in Rails

Rails is a framework that comes with nearly everything included, focusing on conventions over configurations. Minitest is one of these conventions. Minitest is small and fast, and it provides many assertions to make tests readable and clean.However, many alternatives to Minitest are available. The most popular one is RSpec.RSpec has the same goals as Minitest but focuses on readable specifications describing how the application is supposed to behave with a close match to English. Minitest purports that if you know Ruby well, it should be enough.The RSpec project focuses on behavior-driven development (BDD).
