• 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.

• 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.

Node libraries where test isolation and speed matter more than ecosystem breadth.

Java Selenium automation frameworks and large integration suites.
