Product Decisions This Supports

Enables reliable test isolation for code interacting with global variables (e.g., $_SESSION, $_SERVER), eliminating flaky tests caused by state leakage between test cases
Accelerates test infrastructure development by replacing custom global state management logic with a battle-tested solution, reducing engineering time and maintenance overhead
Critical for products requiring high-confidence test coverage (e.g., financial systems, healthcare platforms) where undetected side effects could lead to production defects
Supports roadmap goals for faster test execution cycles by automating state cleanup without manual setup/teardown boilerplate

When to Consider This Package

Adopt when: Your tests modify global state (e.g., superglobals, static variables), you use PHPUnit or similar testing frameworks requiring isolation, and your PHP version aligns with supported ranges (e.g., PHP 8.0-8.2 for v8.x)
Avoid when: Your
