Why Do We Even Need Tests?
summary
Why write tests for code that already works: this talk examines the practical purposes of automated tests, questions rigid testing dogma, and argues for designing tests to meet specific goals. It discusses unit-test definitions, TDD, test pyramids, concrete examples and authorities, and shows how well-chosen tests protect a project’s correctness and finances rather than being written for their own sake.
