jest VS vitest

Acknowledging the benefits of unit testing, I jumped right in to the one and only Jest. Honestly it overwhelms me a little bit too much when I read the docs and there are a lot of things going on in there. But I didn't lose spirit by just reading a docs, otherwise I wouldn't call myself a learner 😅

Jest is a powerful and widely adopted testing framework used by many prominent organizations. Here's a closer look at its features:

One of the most common complaints from developers who use Jest often report slow test execution times when their code includes barrel files #1. While this might not be noticeable in smaller projects, it becomes a significant issue in larger ones.

I hope you now understand what snapshot testing in jest is all about and how it can be implemented in a javascript codebase. If you are looking to learn more about Jest, you can check out their documentation here. Happy Coding!!

This instrumenter is already outdated, but Jest is still using it to get coverage, and we have not found any alternatives to work with Webpack directly.

There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

you have selected a testing framework. In my case, it's Jest with Supertest

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.

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.

For more detailed information on Vitest, refer to the official documentation. fficient Testing in Your React Projects with Vitest.

Vitest

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.
