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).

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.
