In the fast-paced world of software development, delivering high-quality, robust, and reliable applications is paramount. While traditional testing methodologies like unit, integration, and end-to-end tests form the bedrock of quality assurance, they often leave a critical blind spot: the effectiveness of the tests themselves. A high code coverage percentage might give a false sense of security, masking genuinely weak or superficial test suites. This is where Mutation Testing, powered by tools like Stryker, steps in to revolutionize how we perceive and achieve true code quality.
