This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

Vitest is a unit testing framework for JavaScript. Up to now, many teams have relied on Jest, but Jest doesn't play well with Vite, a modern front-end build tool. Using Jest and Vite together forced teams to create two pipelines — one for build and development and one for unit testing — which required tedious configuration of the pipelines with duplicate settings. These problems are solved with Vitest. It is designed specifically for Vite and uses Vite as a bundler. As an additional feature, Vitest has Jest-compatible APIs which makes it possible to use Vitest as a drop-in replacement for Jest in various build setups. However, using Vite and Vitest together provides a better developer experience, and although Vitest is fast, in our experience, it isn't necessarily faster than using Jest.
