Dead Probes Pass: Mutation-Check Your Characterization Tests Before You Refactor

说明与用途

通过进行突变审计，验证您的测试是否真正检测到错误：为每个行为创建三种突变，运行探针与突变矩阵，并保留至少在一种突变上失败的活跃测试。

问题

Legacy code has passing tests that give false confidence because the tests do not detect bugs; refactoring risks introducing regressions.

结果

After a 20‑minute audit, dead probes are identified and removed, leaving a minimal set of alive probes that detect mutations, providing a safety net for refactoring.

工作流

• Draft probes with a free LLM model
• Draft three mutations per behavior
• Run probe‑versus‑mutation matrix on a free server
• Keep only probes that catch at least one mutation

证据

A probe earns trust by failing on mutated code.
