PURPOSE: To facilitate the test operation by collating an expected value of the test result with an actual test result and reporting the collation result to an operator.

CONSTITUTION: A test frame stored in a test file part 11 is used to set the start order of frames required for test items to be executed, input values of frames, and expected values of test results, and an SVP (service processor) 10 is tested in this state to perform comparison with expected values. At this time, the order of frames inputted to the test frame, input values of frames, and expected values are stored as a test file in a test file storage means 12. At the time of executing the same test, frames stored in the test file storage means 12 are successively started by a test file starting means 13 to easily execute the test. If test results do not coincide with expected values, the started frame and the input value are displayed by a test file display means 14 to easily confirm whether the input value is accurate or not. Thus, the test operation is facilitated.
