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 timeouts, ensuring that your tests are isolated, and leveraging tools like async/await for better readability.

Can you explain why timeouts are important?

Timeouts are crucial in asynchronous testing 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?

I recommend using testing frameworks like Jest or Mocha, which have built-in support for async testing. Additionally, libraries like Chai for assertions can enhance your testing experience.

How can I ensure my tests are isolated?

To ensure isolation, use setup and teardown methods to reset the state before and after each test. This prevents tests from affecting each other and leads to more reliable results.
