Jasmine
Behaviour-driven JavaScript testing framework with no external dependencies.
What it is
Jasmine predates most of the current JavaScript testing landscape and supplies structure, matchers, spies and clocks in a single dependency-free package. It remains the default in Angular projects and in browser environments where a build step is undesirable.
Best for
Where it is strong
- Self-contained: spies, clocks and matchers with no extra packages.
- Runs directly in a browser without bundling.
- Extremely stable API — old suites keep working.
Where it falls short
- 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.

Alternatives to Jasmine
If Jasmine is not the right fit, these solve the same problem differently.
Jest
