• Self-contained: spies, clocks and matchers with no extra packages.
• Runs directly in a browser without bundling.
• Extremely stable API — old suites keep working.

• No dependencies to install, audit or upgrade — a real supply-chain advantage for libraries.
• Stable and versioned with the runtime itself.
• Fast, with parallel execution by file and built-in coverage.

• 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, so it is a poor fit for front-end component testing.
• Ecosystem of reporters and matchers is tiny compared to Jest or Vitest.
• TypeScript requires a loader or a build step.
