Leveraging Propagated Infection to Crossfire Mutants
[ICSE 25] Sometimes a simple, localized edit, i.e., adding an additional assertion, may substantially improve the test suite effectiveness by crossfiring mutants.
Ripples of a Mutation — An Empirical Study of Propagation Effects in Mutation Testing
[ICSE 24] Many faults propagate without revealing as failures, suggesting that observing propagated infections can substantially improve test effectiveness through assertion …
To Kill a Mutant: An Empirical Study of Mutation Testing Kills
[ISSTA 23] Mutation scores alone can be misleading. The nature of kills must be considered when evaluating test quality.
