ABNORMAL SYSTEM TEST DATA GENERATING DEVICE, METHOD, AND PROGRAM, PERMITTING READY RECOGNITION OF MULTIPLE INPUT VARIABLES

摘要

PROBLEM TO BE SOLVED: To provide a device for generating abnormal system test data permitting ready recognition of multiple input variables including input variables having mutually dependent relations among one another.;SOLUTION: A variables classifying unit 15 classifies multiple input variables into groups on the basis of the presence or absence of any relation of dependence in conditional expressions to be satisfied by the multiple input variables, and associates the conditional expressions with groups to which related variables belong. A value candidate generating unit 16 generates for each group value candidates on the basis of the conditional expressions associated with the group. A combination generating unit 17 selects, regarding each conditional expression, from each of the other groups for each candidate not satisfying the pertinent conditional expression out of the candidates regarding the group to which variables related to the conditional expression belong, one simple value each dependent on the data pattern of the variables of the pertinent other group, and generates combinations of candidates; the candidates selected from other groups regarding any one conditional expression are common to all the combinations regarding the pertinent conditional expression.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2016,JPO&INPIT
