How can I handle errors in my testing library?

You can handle errors in your testing library by using try-catch blocks and custom error messages.

Can you give me an example of using try-catch in a test?

Sure! Here's a simple example:

try {
  expect(someFunction()).toThrow();
} catch (error) {
  console.error('Error caught:', error);
}

What about asynchronous tests? How do I handle errors there?

For asynchronous tests, you can use async/await with try-catch:

it('should handle async errors', async () => {
  try {
    await someAsyncFunction();
  } catch (error) {
    console.error('Async error caught:', error);
  }
});

Are there any best practices for error handling in tests?

Yes, always provide clear error messages, use specific assertions, and ensure your tests are isolated to avoid cascading failures.
