Field of the Invention The present invention relates to a communication control program testing device, and more particularly to a communication control program testing device for simulating a communication partner and detecting malfunctions in the program during a test for developing a communication control program.

0002

[Prior Art] Conventionally, in the process of developing a communication control program, the operation test of the program was carried out on the actual communication partner (
host/terminal) via a communication line, or each time you develop a communication control program, create a test tool that simulates the communication partner, and connect this tool and the communication control program under test via a communication line. The program under test was executed and the operational results were evaluated using line analyzer trace information, etc.

0003

[Problem to be Solved by the Invention] As mentioned above, in the operation test of a communication control program, there are cases where the operation test is performed by actually connecting to the communication partner (host/terminal) via a communication line. Due to functional constraints and human factors such as terminal operations, there are cases where it is not possible to set conditions for implementing test items.

[0004] Furthermore, if it is not possible to set up an environment for connecting with an actual communication partner, a simulator that simulates the behavior of the communication partner is used, but each time a communication control program is developed, the simulator and the data used by this simulator are created and tested. are being carried out. Therefore, man-hours are required to create a simulator every time a communication control program is developed. In addition, when creating simulation data, registration is mainly done in the form of a code image, making it difficult to create simulation data for multiple terminals/hosts.All test items that should have been performed in the operation test of the communication control program are performed. It is difficult to do so.
