Pressure Mutation Testing Findings

What intentional fault injection taught us about blind spots, and how those findings changed our roadmap.

Testing The Tests

Mutation testing is used to validate that our testing framework catches realistic faults.

For Pressure, early campaigns exposed detection gaps that conventional pass/fail runs did not surface.

What Changed After The Findings

Gaps discovered through mutation campaigns are now treated as roadmap items, not ignored anomalies.

This keeps the validation system honest: if a blind spot is found, it is documented and scheduled for closure.

Why This Matters For Releases

A plugin can pass visible tests and still hide risk if the suite itself has weak detection zones.

Mutation campaigns reduce that risk by forcing the framework to prove it can detect intentional breakage.
