How do I set up Jest in my React Native project?

To set up Jest in your React Native project, you need to install Jest and some additional dependencies. Would you like a step-by-step guide?

Yes, please provide the steps.

First, run npm install --save-dev jest @testing-library/react-native. Then, add a Jest configuration in your package.json.

What should I include in the Jest configuration?

You should include the preset for React Native: "jest": { "preset": "react-native" }. This helps Jest understand your environment.

Are there any specific test files I need to create?

Yes, you can create a __tests__ directory and add your test files there. Each test file should end with .test.js.
