Pick JUnit when
- Java/JVM projects
- CI pipelines
- TDD and regression testing
- Computer science teaching
When JUnit is not a fit
- Non-Java codebases . Python/JS/.NET need their own test runners (Guess: pytest, Jest, xUnit)
- Buyers wanting vendor support contracts or SLAs . none exists
- Test-management shoppers . that's a different product class (PractiTest, Testiny)
- Anyone judging it by marketing pages . it has none; it's a library, not a SaaS
