Jest vs node:test
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
- Everything in one dependency, with defaults that work for most projects on day one.
- The largest ecosystem of matchers, reporters and framework presets in JavaScript.
- Snapshot testing is genuinely useful for serialisable output when used with restraint.
- 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.
Limitations
- Native ESM support remains awkward, and the Babel transform layer is a recurring configuration tax.
- Noticeably slower than Vitest on large suites.
- jsdom is not a browser; subtle DOM and CSS behaviour differs from reality.
- 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.
Best for
Existing JavaScript codebases, React Native, and teams that value ecosystem depth over raw speed.
Node libraries and backend services that want a dependency-free test setup.
