Making PHPUnit Better
summary
Walks through a concrete rewrite of PHPUnit’s execution core that replaces brittle global state with composable TestSuite and TestRunner objects and a compact test collection representation, removes the global TestResult lifecycle, and collapses the tangled ~1500 LOC runner into a clear proof‑of‑concept. Shows the actual code changes, bench results (faster code coverage collection, Windows CI fixes), enables randomized and distributed execution, and demonstrates the new runner working end to end.
