Abstract: Comparing a sample image to a reference image. Differences between the color channel values of the pixels in the sample image and the corresponding color channel values for the corresponding pixels in the reference image are calculated and compared to predefined tolerances. Based on the comparisons, a pixel status for the pixels in the sample image is defined. An image status indicating whether the sample image differs from the reference image is defined based on the defined pixel status.

Abstract: A system and method for accelerated reliability testing of computer system software components over prolonged periods of time provides a uniform, extensible, reporting framework that includes a plurality of reporting clients, at least one controller. The system and method are adaptable for operation over a dedicated intranet as well as the Internet. It provides for tracking the reliability of system components and logs failures of varying severity that may be expected to occur over time. This data is useful, among other things, for estimating mean time between failures for software being tested and expected support costs. This information is particularly useful in providing a reliability measure where multiple independently developed software modules are expected to function together.
