PROBLEM TO BE SOLVED: To reduce trouble of application test generation.;SOLUTION: An instruction string division means 11 reads an instruction string 21, and divides the instruction string by a division instruction. A communication log obtaining/classification means 12 reproduces the divided division instruction string, and outputs to a user agent 40 an operation instruction. The communication log obtaining/classification means 12 obtains a request transmitted by the user agent 40 according to the operation instruction and a communication log of a response to the request, and classifies them in each division instruction string. An automatic test generation means 13 generates a test nucleus changing the request of a target based on the classified communication log, and generates an automatic test 24 wherein the instruction string is combined.;COPYRIGHT: (C)2011,JPO&INPIT
