• No dependencies to install, audit or upgrade — a real supply-chain advantage for libraries.
• Stable and versioned with the runtime itself.
• Fast, with parallel execution by file and built-in coverage.

• Universal in PHP — every framework builds on it.
• Mature mocking, data providers and coverage integration.
• Well documented and extremely stable.

• No DOM environment, so it is a poor fit for front-end component testing.
• Ecosystem of reporters and matchers is tiny compared to Jest or Vitest.
• TypeScript requires a loader or a build step.

• Major versions drop older PHP releases aggressively, forcing upgrade work.
• Verbose compared to newer wrappers such as Pest.
• Coverage requires an extension, which slows runs significantly.

Node libraries and backend services that want a dependency-free test setup.

Every PHP project, directly or through a wrapper.
