Kent Beck: Composable Tests
Summary
Kent Beck discusses the principles of composable tests, focusing on isolation, composition, and pruning to create faster, more readable, and more maintainable test suites. He argues that composing tests, rather than duplicating tests, can preserve predictive coverage with fewer tests (NxM), and addresses resistance from some testers who fear reducing assertions.
