PROBLEM TO BE SOLVED: To provide an automatic test system for station data that accurately and efficiently executes an update job of station data. ;SOLUTION: A text storage section 31 stores station data generated by a network manager from an application system 11 via a transmitter-receiver 37, a difference extract function section 27 compares the data with in-operation station data stored in a text storage section 34 to extract difference data, and a test item extract function section 28 generates a test scenario on the basis of the difference data. A test processing function section 35 extracts station data from a storage medium to start the test scenario for a new communication processing unit and executes a connection test with a new existing communication processing unit on the basis of the station data. An update processing function section 29 executes updating the in-operation station data stored in a storage medium when the test result from the test processing function section 35 indicates a successful result.;COPYRIGHT: (C)2000,JPO
