Safety Testing Method of Complex Software System Based on Fault Tree
Dongfei Liu · 2008
As the development of the information technology, the computers are used widely.Software reliability and safety are noted by people. The software test is the very important way to guarantee the quality of software. For a long time, software test was just be carried on manually and the design of test case just by our intuition and experiences. The efficiency and cost of testing can't satisfy our need,and it also can not ensure to enhance the quality of software. In this paper, the authors use the technology of fault tree analysis based on safety requirement to analyze the fault probability of all sections of the software to find the key sections that will be influence the safety. Based on that result, the authors use the minimum cut set to classify the data of testing and produce the test case.
