Which testing framework is better: Jest or Mocha?

I'm trying to decide between Jest and Mocha for my JavaScript testing. Which one should I choose?

Both Jest and Mocha are popular testing frameworks, but they serve slightly different purposes. Jest is an all-in-one framework with built-in assertion libraries, while Mocha is more flexible and allows you to choose your own assertion library.

What are the main advantages of using Jest over Mocha?

Jest offers a zero-config setup, snapshot testing, and built-in mocking capabilities, making it easier for beginners. It also runs tests in parallel, which can speed up the testing process.

Are there any specific scenarios where Mocha might be a better choice?

Yes, if you need more control over your testing environment or want to integrate with other libraries like Chai for assertions, Mocha might be a better fit. It's also great for testing Node.js applications.

Can I use both Jest and Mocha in the same project?

Yes, you can use both in the same project, but it might complicate your setup. It's usually better to stick with one framework for consistency.
