Vitest vs Pest
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
- Fastest watch-mode feedback of the JavaScript runners, by a wide margin on large repos.
- Zero-config ESM and TypeScript — the single biggest source of Jest configuration pain simply disappears.
- Jest-compatible API means migration is usually a day, not a quarter.
- Much less boilerplate than raw PHPUnit for the same coverage.
- Architecture testing — enforcing layering rules as tests — is a genuinely useful addition.
- Fully compatible with existing PHPUnit tests, so adoption is incremental.
Limitations
- Assumes Vite. On a Webpack or Metro project the advantage largely evaporates.
- Younger ecosystem; a handful of niche Jest plugins have no equivalent.
- Browser mode is still maturing relative to a dedicated component test runner.
- Another abstraction layer to debug when something goes wrong underneath.
- Strongest in the Laravel world; thinner elsewhere.
- Smaller ecosystem of examples than PHPUnit.
Best for
Any Vite-based project, and most new JavaScript projects generally.
Laravel teams and modern PHP projects that find PHPUnit verbose.
All of these integrate with: GitHub Actions.
