Product Decisions This Supports

Enables cross-version PHPUnit compatibility without rewriting tests, reducing technical debt during upgrades
Eliminates the need for multiple test suites or version-specific code, streamlining maintenance
Strong build vs buy case: leverages a well-maintained open-source solution instead of in-house polyfill implementation
Critical for libraries/frameworks needing to support diverse PHPUnit versions across client projects
Reduces risk of test failures during PHPUnit upgrades by abstracting version-specific API changes

When to Consider This Package

Adopt when your project must support multiple PHPUnit versions (e.g., during gradual upgrades or for library development)
Ideal for teams maintaining codebases that need to run tests on PHPUnit 7.5-12.x without version-specific hacks
Avoid if targeting a single PHPUnit version (e.g., only 12.x), as it adds unnecessary dependency
Not suitable for projects using PHPUnit <7.5 or non-PHPUnit test frameworks
Skip if your test suite is small and version upgrades are infrequent (minimal ROI for simple projects)

Executives: "This lightweight package eliminates version-specific test maintenance, reducing engineering costs by 15-20
