QML tips and tricks
18 October 2022
When you make larger changes to your code base, you likely want to validate there are no side effects.
Unit testing the complete code base is of course the golden standard, but somewhat unrealistic in most cases.
The next best is a comprehensive set of Squish test cases, but when you are about to make a large change to your application, your focus might likely not be towards building that.
A solution that comes from the box "better than nothing" is to run your original and modified applications side by side and comparing them.
For that I create a small application which makes it easy to take a screenshot of each and compares them.
The example code showcased in this video is available here: https://github.com/KDAB/kdabtv/tree/master/Qt-Widgets-and-more/screenshot-comparison
