Reference Response time/Turnaround time/Throughput Refer to “Chapter 8-2-2 System evaluation indexes.” In system testing, the following types of testing may be conducted depending on the purpose. Name Description Function testing Verifies that all of the required functions are included. Performance testing Verifies that the processing performance, including response time, turnaround time, and throughput, fulfills the requirements. Exception handling testing Verifies that error processing functions and recovery functions operate normally. Load testing (Rush testing) Applies a load to the system through such means as inputting a large amount of data and simultaneously increasing the number of operating computer terminals, and verifies that the system can withstand the load. Operability testing Verifies that the system is easy to operate for the user (system user department). Regression testing Verifies that no other programs were affected when errors discovered in any of the test processes were modified or when changes were made to the specifications. Penetration testing (Intrusion testing) Detects the system’s security holes and firewall weak points (vulnerability) by actually attempting an attack or intrusion from outside. ●Operational testing “Operational testing” uses real business data to verify whether the system is appropriate for the realities of the business and whether it can be operated in accordance with the operation manual. It is conducted mainly by the user (system user department). In operational testing, the following items are tested. Item Reference Receiving inspection “Receiving inspection” refers to testing and acceptance of a system by the user (system user department). 123 Description Business function Verifies that functions required in conducting business are fulfilled. Operability Verifies that the system is easy to operate for the user (system user department). Anomaly measures Verifies that measures have been taken in case of anomalies such as data anomalies, abnormal operation, and equipment anomalies. Throughput Verifies that throughput is sufficient using the current equipment configuration. Processing time Verifies that response times are within the acceptable range. (5)Test result evaluation In order to receive system inspection, satisfactory test results must first be achieved. At such time, it is necessary to consider the criteria for evaluating the system based on the test results.
