AVA vs TestNG
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- Process isolation catches hidden coupling between tests that other runners hide.
- Concurrent by default, so suites stay fast without configuration.
- Clean, small API with no magic globals.
- 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.
Limitations
- No DOM environment; not for front-end work.
- No built-in mocking or snapshots comparable to Jest.
- Smaller community than the mainstream runners.
- 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.
Best for
Node libraries where test isolation and speed matter more than ecosystem breadth.
Java Selenium automation frameworks and large integration suites.
