Embodiment Construction
[0018] The invention provides a CPU online testing method based on gray box testing, and the algorithm can be applied to fields including but not limited to safety signal systems, industrial control systems and the like. The present invention makes a higher-level algorithm improvement to the above algorithm, overcomes the shortcomings of the prior art, and can achieve the purpose of covering CPU function failures.
[0019] Gray Box (GrayBox) is a device in which the working process on a program or system is partially recognized. Gray box testing, also known as gray box analysis, is a software debugging method based on limited knowledge of the internal details of the program. Testers may know how system components interact with each other, but lack detailed knowledge of internal program functions and operations. For internal processes, gray box testing treats the program as a black box that must be analyzed from the outside.
[0020] Gray box testing does not require testers ...
