Jasmine vs AVA
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
- Self-contained: spies, clocks and matchers with no extra packages.
- Runs directly in a browser without bundling.
- Extremely stable API — old suites keep working.
- 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.
Limitations
- Feels dated; snapshot testing and modern mocking are absent or bolted on.
- Momentum has moved to Jest and Vitest, including within the Angular ecosystem.
- Weaker TypeScript ergonomics than newer runners.
- No DOM environment; not for front-end work.
- No built-in mocking or snapshots comparable to Jest.
- Smaller community than the mainstream runners.
Best for
Existing Angular codebases and browser-native test setups.
Node libraries where test isolation and speed matter more than ecosystem breadth.
