Abstract
Abstract A computer hardware-related device and method is used for regression testing techniques involving the testing of computer hardware and/or software application(s). Input data is received from a host, and is directed to software application(s) on a System Under Test (SUT). Command are also received from the host, which causes the capture of a representation of visual display data from a visual display device on the SUT. A representation of this visual display data is then sent to the host. When a command and a representation of visual display data from the host (previously obtained from the SUT) is received, a new representation of visual display data is captured from the visual display device on the SUT. A comparison is than made between the new visual display data representation and the visual display data representation received from the host.
