vite-jest VS vitest

Even the most official workaround, vite-jest, still has issues to work through, like a lack of Windows support.

I had originally planned to keep using Jest during the migration of CRA to ViteJS, but I kept running into issues, mainly because Jest support for ES Modules is still experimental. There is a Vite plugin called vite-jest but it's still very much a work in progress.

Then I tried Vite. Vite also supports lots of things out of the box (especially ESM!). Its HMR - hot module replacement is blazing fast. I can also use plugin like vite-jest (switch to esbuild-jest later on) to replace Babel and speed up my tests. This is the first time I have a relatively "GOOD" DX.

Using something like Vitest, Jest, or Mocha didn't work because:

However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

Next we’ll install Vitest and happy-dom to the project by running:

vitest is a testing framework similar to jest that integrates well with projects using Vite. It allows us to reuse plugins and configurations already set up in the vite.config.ts, making the test setup process easier.

Are you looking to migrate from Jest to Vitest for your React application? Look no further.

In addition to those tools, a new testing framework has emerged named Vitest. Vitest is built on top of Vite and has many exciting features to keep improving the overall developer experience for writing tests. This post shows you how to set up Vitest in your existing Angular project.
