    Abstract: The embodiments herein relate to Graphical User Interface (GUI) testing and, more particularly, to automate the testing of GUI for non-standard displays. Initially, an automation module is pre configured with the test cases that are required to test the GUI of the Device Under Test (DUT). Further, the DUT's display is auto configured with an interpretation & reconstruction module which fetches the display parameters and allocates required memory in a memory buffer. Later, the automation module provides the system inputs to DUT in which test cases are executed. Now, the interpretation & reconstruction module interprets and reconstructs the GUI content of DUT by fetching it from its display port. Later, the reconstructed display content will be updated to the memory buffer which is further verified by automation module.
