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

• Mature parallel-execution and grouping model, ideal for large Selenium suites.
• Data providers make data-driven testing straightforward.
• Test dependencies and ordering, which JUnit deliberately avoids.

• 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.

• XML suite configuration is dated and error-prone.
• Test dependencies encourage ordering coupling that makes suites fragile.
• Community momentum favours JUnit 5 for new projects.
