Abstract:
1. A test method for a distributed processing system including a plurality of processing units that execute a program for performing predetermined processing in accordance with input data, the method comprising: supplying input data to the program running on the processing units; generating a feature pattern of the supplied input data, determining whether or not a feature pattern which is the same as the generated feature pattern is stored in a storing unit that stores feature patterns corresponding to previously tested input data, and if the feature pattern which is the same as the generated feature pattern is not stored, calculating expected data which is data expected to be obtained as a result of performing the predetermined processing in accordance with the supplied input data; determining, in a case where an error occurs so that the predetermined processing of the program is not completed normally, that a test performed by using the supplied input data failed; and in a case where an error does not occur so that the predetermined processing of the program in accordance with the supplied input data is completed normally; determining, if the feature pattern which is the same as the generated feature pattern of the input data is stored in the storing unit, that the test performed by using the supplied input data succeeded; and determining, if the feature pattern which is the same as the generated feature pattern of the input data is not stored in the storing unit, a result of the test performed by using the supplied input data by comparing the calculated expected data with result data of the program.
