Product Decisions This Supports

Enables integrating performance validation into existing PHPUnit test suites without major workflow changes, supporting a "shift-left" approach to performance.
Critical for teams prioritizing performance as a core quality attribute; helps define and enforce performance expectations in the development lifecycle.
Build vs buy: ideal for teams needing a lightweight solution rather than building custom performance assertions from scratch.
Use cases: e-commerce checkout flows, API response time SLAs, or any code path where runtime consistency is critical to user experience.

When to Consider This Package

When your team uses PHPUnit and needs simple, repeatable performance checks in CI.
For projects with measurable performance thresholds that can be validated via execution time assertions.
When minimal setup and low maintenance are priorities over advanced profiling capabilities.
When to look elsewhere: if using non-PHPUnit testing frameworks, requiring advanced profiling (e.g., memory, CPU), or if the package's lack of recent updates (2
