It allows developers to forbid mocking specific methods on particular classes or modules, raising a test failure when violations occur. Motivated by AI-generated test code that introduces unnecessary mocks (e.g., mocking Hash methods), the gem is especially useful in larger codebases to communicate and enforce testing conventions, such as preventing mocking of ActiveRecord methods when a real database is available. The .and_call_original pattern is exempt from restrictions. ## Full article daily.dev links to this article rather than hosting it.
