Mutator Laravel Package

Product Decisions This Supports

• Enables custom mutation testing strategies tailored to specific codebases, avoiding one-size-fits-all tools
• Supports building internal tooling for code analysis without heavy dependencies (build vs buy decision)
• Facilitates integration into CI/CD pipelines for continuous mutation testing, enhancing test coverage proactively
• Ideal for scenarios requiring precise mutation control (e.g., security vulnerability testing, compliance checks)

When to Consider This Package

• Consider when needing lightweight, customizable mutation operators beyond standard tools
• When integrating mutation steps into existing static analysis or testing pipelines without framework overhead
• When the team has expertise in mutation testing concepts and needs fine-grained control
• Avoid if requiring full mutation testing suite (e.g., Infection's test runner, reporting), or if the project is small and standard tools suffice
