JUnit 5 Architecture or "What's Jupiter?"

This technical article analyzes the architecture of JUnit 5, explaining its split into the Jupiter, Vintage, and Platform sub-projects. It contrasts this with JUnit 4's monolithic design, discusses the problems of tight coupling, and details how JUnit 5's modular structure with published APIs improves maintainability and tool integration.
