In this Test Talk, Thierry Zuzel discusses how Keysight's Eggplant, our versatile automation solution, can be used to test the functionalities of various applications, including Computer-Aided Design (CAD) and Product Lifecycle Management (PLM) applications. By using computer vision technology, Eggplant can interact with CAD and PLM application's user interface (UI). We also delve into how Eggplant can identify and interact with UI elements such as buttons, menus, and dialog boxes which enables Eggplant to simulate user actions and validate the expected behaviour of the application's UI.
