Testing 101: What Are Integration Tests & How to Write Them in Swift

In this episode of Testing 101, we dive into integration tests and explain how they differ from unit tests. While unit tests focus on testing individual functions or classes, integration tests ensure that different components in your app work together smoothly.

I’ll walk you through a real-world demo where we integrate an API client, a database, a discount calculator, and a logger—testing them all in one flow using Swift.
