I Delete Tests Every Night (On Purpose)

Why watch

Kent C. Dodds demonstrates his automated approach to pruning low-signal tests nightly using Cursor IDE. The video explains how to identify and delete tests that add minimal value (tiny wrappers, magic-number assertions, unrealistic edge cases), presents a real cleanup PR showing +122/-703 line changes, and provides a testing-principles.md framework for evaluating test signal. Ideal for developers using AI coding assistants that generate excessive low-quality tests.
