Testing for Resilience

Stop Trusting Coverage. Start Testing for Failure.

Code coverage tells you what ran. Mutation testing tells you what broke. In this piece, we break down why 100% test coverage means nothing if your tests don’t catch logic failures and how mutation testing exposes the blind spots that lead to real exploits.
