Explore best practices for testing Angular applications in this conference talk from ng-conf. Learn why writing tests is crucial, how to leverage Angular CLI for testing, and techniques for handling asynchronous tests. Dive into practical demonstrations, including a delayed echo server and debounced echo server, to understand common testing challenges. Discover solutions for long promise chains, working with timers, and testing XHR/HttpClient interactions. Gain insights into unit testing, asynchronous testing in Protractor, and using async/await in tests. Understand the benefits of AOT testing and component harnesses to improve your Angular application's reliability and maintainability.
