How can I effectively test UI components in my application?

You can use tools like Jest and React Testing Library to test your UI components. They allow you to simulate user interactions and check if the components behave as expected.

What are some best practices for writing these tests?

Some best practices include keeping tests isolated, using descriptive names, and testing both the happy path and edge cases.

Can you give me an example of a simple test case?

Sure! For a button component, you might test if it renders correctly and if it calls a function when clicked.

How do I set up Jest for my project?

You can set up Jest by installing it via npm with npm install --save-dev jest and then configuring it in your package.json.
