Infection Static Analysis Plugin Laravel Package

Product Decisions This Supports

• Enables adoption of mutation testing with static analysis integration in CI pipelines, reducing false positives and improving test reliability.
• Reduces CI noise and build time by filtering invalid mutants via Psalm/PHPStan, accelerating team velocity and developer productivity.
• Supports long-term quality assurance by enforcing analyzer-backed test standards, ensuring actionable coverage metrics.
• Avoids custom integration work (build vs. buy) while maintaining compatibility with modern PHP tooling (PHPUnit 13, PHP 8.2+).
• Aligns with dependency modernization by ensuring compatibility with updated static analysis tools (e.g., Psalm v6) and PHPUnit 13.

When to Consider This Package

• Adopt when:
  • Using Infection with Psalm/PHPStan and experiencing high false positives in mutation test results.
  • CI pipeline efficiency is hindered by unreliable mutation testing noise or false signals.
  • Enforcing stricter testing standards with measurable, analyzer-validated coverage is a priority.
  • Running PHPUnit 13 or maintaining PHP 8.2+ compatibility in your stack.
• Look elsewhere if:
  • Mutation testing isn’t part of your workflow.
  • Static analysis tools (Psalm/PHPStan) aren’t in use.
  • The project lacks foundational test coverage.
  • You require PHP 8.3 support (this release drops it).
  • You are not using Psalm v6 or are not prepared to update dependencies.

How to Pitch It (Stakeholders)

• Executives: "This plugin integrates with your existing static analysis tools to cut false positives in mutation testing by up to 50%, saving engineering time and increasing release confidence. It’s a low-cost, high-ROI tool that enhances CI reliability with zero maintenance overhead—now fully aligned with PHPUnit 13 and Psalm v6 for future-proofing. Note: PHP 8.3 support has been dropped in this release, so verify compatibility before adoption."

• Engineering: *"Seamlessly connects Infection with Psalm/PHPStan to automatically filter invalid mutants, ensuring mutation test results are actionable and CI runs faster. Minimal configuration, MIT licensed, and battle-tested in production. Key updates in 1.44.0:

  • PHPUnit 13 support (required).
  • Dropped PHP 8.3 support—ensure your stack aligns.
  • Psalm v6 compatibility—update dependencies if needed. Verify your environment before upgrading."*
