What are the best practices for asynchronous testing?

Asynchronous testing involves testing code that runs in a non-blocking manner. Key practices include using proper assertions, ensuring timeouts are set, and leveraging tools like async/await for clarity.

Can you explain why timeouts are important in async testing?

Timeouts are crucial because they prevent tests from hanging indefinitely. They ensure that if a promise doesn't resolve in a reasonable time, the test fails, allowing you to catch issues early.

What tools do you recommend for async testing?

Popular tools for async testing include Jest, Mocha, and Cypress. They provide built-in support for handling asynchronous code effectively.

How do I handle errors in async tests?

You can handle errors in async tests by using try/catch blocks within async functions or by returning a rejected promise and asserting the error in your test.
