Jasmine vs xUnit.net
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.
- Per-test instance isolation eliminates a whole class of shared-state bugs by design.
- Idiomatic modern C# — no attribute soup.
- The default in current .NET project templates.
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.
- Fewer built-in assertions than NUnit; most teams add FluentAssertions.
- The isolation model surprises developers migrating from NUnit.
- Parallelism defaults occasionally bite on integration tests.
Best for
Existing Angular codebases and browser-native test setups.
New .NET projects.
