An automated system for implementing visual testing of a Graphical User Interface (GUI) of an implemented product is provided. A codified user experience design is used to automatically create precompiled code. The precompiled code is executed to generate a GUI based on the intended codified user experience design. The implemented product code is executed to generate a GUI of the implemented product code. Screenshots of the GUIs are compared to perform automatic visual testing of the implemented product code from the codified user experience design.
