Publication number: 20140289706Abstract: A test case is generated by receiving software specification, generating a test case including a test input value for particular software from the software specification, as well as an expected output value expected to be obtained as an output value when the software is executed by inputting the test input value, and checking whether a value that can be output in the software specification is included in the expected output value. As a result of the check, if it is determined that the output value that can be output in the software specification is not included in the expected output value, a test case including the value that can be output in the software specification as well as a corresponding test input value is generated and added to the test case that has been generated.Type: ApplicationFiled: February 3, 2014Publication date: September 25, 2014Applicant: Hitachi, Ltd.Inventors: KUNIHIKO MIYAZAKI, Naoto SATO, Shinji ITOH, Sadahiro ISHIKAWA, Kiyoshi YAMAGUCHI, Hiroki MORI
