Mutation Testing, Finally a Good Measure of Test Quality?
summary
Introduces mutation testing as a way to measure test quality by injecting small code changes (mutants) and checking whether the test suite detects them. Covers tools and techniques for creating and running mutants, and explains how mutation scores reveal weaknesses that code coverage misses. Discusses using mutation testing to improve and validate automated tests in practical projects.
