Evaluation of graphical output of graphical software applications executing in a computing environment

摘要

Graphic objects generated by a software application executing in a computing environment are evaluated. The computing environment includes a graphical user interface for managing I/O functions, a data storage device for storing computer usable program code and data, and a data processing engine in communication with the graphical user interface and the data storage device The data processing engine receives and processes origin data from the data storage device to produce projected values for data points in the graphic image intended to be displayed. The data processing engine also creates and processes a snapshot of the displayed graphic object to produce actual values of data points in the displayed graphic object, compares the projected values to the actual values, and outputs an indication of the degree of similarity between the intended graphic object and the displayed graphic object.

1. A computer-implemented method of evaluating a displayed graphic object generated by a software application executing in a computing environment, said method being performed in a test computer and comprising:
receiving origin data defining the graphic object to be displayed; calculating projected values of data points in the graphic object defined by the received origin data; capturing a snapshot of the graphic object actually displayed on a computer display when the software application executes in the computing environment; extracting, from the snapshot, actual values of data points in the displayed graphic object; comparing the actual values of data points in the displayed graphic object to projected values of corresponding data points in the defined graphic object; and based on the results of the comparison, outputting an indication of the degree of similarity between the actually displayed graphic object and the graphic object defined by the received origin data.
