## Snapshot Testing ## Snapshot Testing
Snapshot Testing is a testing technique that can be used in Swift (and other programming languages) to test the user interface (UI) of an application.
In Snapshot Testing, a snapshot of the UI is taken and compared to a previously saved snapshot to check if any changes have been made. This technique can be used to ensure that changes to the UI do not break the existing functionality of the application.
