I will not go into detail about migrating your unit tests, as every project has its own test setup, and generalizing it would be very difficult. You can read and learn more about both of them in JEST docs and Vitest docs. - Source: dev.to / 5 days ago

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. - Source: dev.to / about 2 months ago

Next we’ll install Vitest and happy-dom to the project by running:. - Source: dev.to / about 2 months ago

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. - Source: dev.to / 3 months ago

Mocha as the test runner, Chai as the assertion library, and the Hardhat Chai Matchers to extend Chai with contracts-related functionality. - Source: dev.to / almost 2 years ago

Assertion library we used: Chai (comes with a lot of plugins worth exploring). - Source: dev.to / about 2 years ago

While this is fine and I could have perfectly moved all my tests to use said assertion style, I like the descriptive way Jest tests look like. As a quick way to maintain certain similarity I reached for ChaiJS, an assertion library that is mainly used with mocha. Chai offers expect like assertions that can arguably be more descriptive than Jest’s. Instead of writing expect(…).toBe(true), you’d write... - Source: dev.to / over 2 years ago

The library offers a BDD testing style and fully exploits javascript promises - the resulting tests are simple, clear and expressive. Chakram is built on node.js, mocha, chai and request. - Source: dev.to / about 3 years ago
