<P>PROBLEM TO BE SOLVED: To solve a problem in which: leakage occurs during an operation test in updating a program when a developer creates test data. <P>SOLUTION: A program test device includes: means for generating values in all ranges which can be input about designated variables as test data to one or more predetermined variables with respect to an update program as the object of a test after an existing program is changed, and for generating the execution conditions of the test with which the generated values are associated as the test data of the individual variables; means for acquiring and storing the output of an existing system in the case of performing a test operation based on the variables shown by the execution conditions generated by the existing system based on the existing program; means for, in the case of performing the test operation based on the variables shown by the execution conditions generated by a new system based on the update program, acquiring and storing the output of the new system; and means for comparing the both outputs of the existing system and the new system, and for perceptibly outputting a difference included in the result of the comparison. <P>COPYRIGHT: (C)2013,JPO&INPIT |
