Which is better for async testing: Jest or Mocha?

Both Jest and Mocha are popular testing frameworks, but they have different strengths. Jest is known for its built-in mocking capabilities and ease of use, while Mocha offers more flexibility and is often paired with other libraries for assertions and mocking.

Can you explain how async testing works in both frameworks?

Sure! In Jest, you can use async/await directly in your tests, making it straightforward. Mocha also supports async testing, but you need to use the 'done' callback or return a promise.

What are some pros and cons of using Jest for async testing?

Pros of Jest include its simplicity and built-in features like snapshot testing. However, it can be less flexible than Mocha for complex setups.

Are there any specific scenarios where one is preferred over the other?

Yes, Jest is often preferred for React applications due to its integration with the React ecosystem, while Mocha is favored in projects requiring more customization.
