Spock vs. Supermutants: Specification Testing Meets Mutation Testing
summary
Shows how the Spock testing framework (Groovy-based BDD) can be combined with mutation testing to improve test quality: Spock produces readable, AsciiDoc-capable reports and high line coverage, while mutation testing injects code mutations and runs the test suite to measure how many mutants are killed, yielding a percentage that indicates test effectiveness.
