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.

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.
