As in the case of hardware, the goal of fault detection in software is to determine if a fault has occurred within a system. Single-version fault tolerance techniques usually use various types of acceptance tests to detect faults. The result of a program is subjected to a test. If the result passes the test, the program … See more Fault containment in software can be achieved by modifying the structure of the system and by imposing a set of restrictions defining which actions are permissible within the … See more A program is represented by the flowgraph shown in Fig. 7.2.
