Testing 101: What Are UI Tests & How to Write Them in Swift/iOS

In this episode of Testing 101, we explore UI tests and explain how they differ from other types of testing. While unit tests focus on individual components, UI tests ensure that the user interface behaves correctly as a whole.

I’ll walk you through a real-world demo, setting up a UI test in Xcode, simulating user actions, and making your tests more reliable by mocking a Web API call.
