iOS Dev 32: Getting Started with Snapshot Testing | Swift 5, XCode 13

In this video, we cover the basics of Snapshot Testing in iOS.

We start by creating an app that displays 'Hello World' with white/black background depending on the nightMode value.

Next, we learn how to write snapshot tests, record/update snapshots, and view differences in failing snapshots.

Finally, we implement a helper function that allows us to be able to create storyboard instances of a ViewController.

Thanks for sharing your experience with us n_n.
Can you make a video explaining how to use correctly the wait strategy when creating snapshots for async views?

Thank you very much for your video content. Do you have any suggestions to reduce the time in tests written by adding wait time in a project with many snapshots?

Hello sir, you made incredible content. It helps me a lot in learning Swift. Do you mind making the API for the yummie food order app function again? I can make some donation to you if you need.
Thank you and have a meaningful Thanksgiving with your family.
