Handling Asynchronous Behavior with setTimeout (async/await) | Unit testing Angular

In this video, we learn how to unit test asynchronous behavior in Angular, including code that uses setTimeout, async, and await. Async logic is very common in real applications—API calls, delayed actions, and background tasks—and testing it correctly is a must for reliable apps. You’ll see how to wait for async code to finish and assert the expected results without flaky tests. 🚀 What You’ll Learn: What async code means in Angular testing Testing setTimeout logic Using async and await in unit tests Waiting for async operations to complete Writing stable, predictable async tests Common mistakes to avoid
