How do I configure Jest snapshots for my project?

To configure Jest snapshots, first ensure you have Jest installed. Then, create a test file and use the toMatchSnapshot() method in your tests.

Can you give me an example of how to use toMatchSnapshot()?

Sure! Here's a simple example:

import MyComponent from './MyComponent';

test('renders correctly', () => {
  const tree = renderer.create(<MyComponent />).toJSON();
  expect(tree).toMatchSnapshot();
});

What should I do if my snapshot test fails?

If a snapshot test fails, you can review the changes and decide whether to update the snapshot using jest --updateSnapshot or fix the component.
