Rails Testing

A solid reference for Rails testing with RSpec that covers the basics through advanced patterns. You get 46 rules across model tests, request specs, system tests with Capybara, background job testing, and FactoryBot usage. The priority system is helpful: it pushes critical stuff like test data management and four-phase structure first, then moves into specifics like enum testing and page objects. Nice touch that it separates testing job enqueuing from execution, which trips people up constantly. The anti-pattern coverage (mystery guests, flaky tests, sleep in Capybara) addresses real pain points. If you're setting up a new Rails test suite or trying to standardize an existing one, this gives you sensible defaults without being dogmatic.
