When should I run Dev Fuzz Testing?

This skill is designed to run as 'Gate 4' in the development cycle, immediately after unit testing is completed and before moving to property-based testing.

What is the difference between coverage and mutation testing?

Code coverage measures which lines were executed, while mutation testing (like Infection) measures if your tests actually detect changes in logic, ensuring your assertions are meaningful.

What happens if my MSI score is too low?

The skill will fail the gate (typically if MSI < 80%), requiring the developer to add more robust test assertions to 'kill' the escaped mutants.

Which languages are supported by this skill?

Currently, this skill is specifically optimized for PHP applications using the Infection mutation testing framework.

安全与测试

Validates test suite effectiveness and identifies edge cases in PHP applications using mutation testing with Infection.

Dev Fuzz Testing (Gate 4) is an automated testing orchestrator designed to uncover hidden weaknesses in your test suites. By injecting faults into your source code via mutation testing—specifically using Infection for PHP—this skill ensures your unit tests actually verify logic rather than just achieving surface-level coverage. It is an essential stage for critical parsing and input-handling code, providing high-fidelity feedback through Mutation Score Indicators (MSI) to prevent production crashes and handle unexpected input scenarios.
