How do I handle errors in async tests?

You can handle errors in async tests by using try-catch blocks or by returning a rejected promise.

Can you give me an example of using try-catch in async tests?

Sure! Here's a simple example:

async function testFunction() {
    try {
        await someAsyncOperation();
    } catch (error) {
        console.error('Error occurred:', error);
    }
}

What about using promises instead?

You can also handle errors by returning a promise. For example:

it('should handle async errors', () => {
    return someAsyncOperation().catch(error => {
        expect(error).toBeDefined();
    });
});

Are there any libraries that help with this?

Yes, libraries like Jest and Mocha provide built-in support for handling async tests and errors.
