Jest vs Cypress for Integration Testing: Which One to Choose?

What are the main differences between Jest and Cypress for integration testing?

Jest is primarily a JavaScript testing framework focused on unit testing, while Cypress is an end-to-end testing framework that runs in the browser. Jest is great for testing individual functions and components, whereas Cypress is designed for testing the entire application flow.

Can I use Jest for integration tests?

Yes, you can use Jest for integration tests, especially for testing React components and their interactions. However, for full end-to-end testing, Cypress is more suitable.

What are the advantages of using Cypress over Jest?

Cypress offers real-time reloading, a user-friendly interface, and the ability to test in a real browser environment, which makes it easier to debug and see how your application behaves.

Are there any scenarios where Jest is better than Cypress?

Yes, Jest is better for unit testing and when you need fast feedback on small code changes. It's also more lightweight and easier to set up for simple tests.
