Abstract

PURPOSE:To improve the test efficiency, the test quality, and the test accuracy of the application software contained in its node by providing an inter node communication simulator to each node and performing the pseudo communication with other nodes only in its own node. CONSTITUTION:Both a transmission software B and a reception software C are not actuated in a test state, and only an inter-node communication simulator F works. Even under such conditions, the same operation state is secured as long as a telegram stays in another node transmission queue 5. At the same time, the simulator F reads the telegram of another queue 5 and then reads the corresponding answer telegram out of another node telegram file 12 based on the prescribed conditions. This answer telegram is stayed in another node reception queue 10 and then informed to an application software E. In such a constitution, the test efficiency, quality and accuracy can be improved for the software E contained in its own node.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a test method for application software for communication between two Fs.

[Conventional technology]

Conventional no-F communication application software testing is
This is done by exchanging takes using communication lines.

[Problem to be solved by the invention]

In the conventional test method for notebook-to-note communication application software described above, the communication line is prepared.

It could not be carried out until various hardware preparations and communication control tests were completed. Therefore, the test period between nodes is set in advance for a long period of time, and there are drawbacks such as delays in the start of the application software test itself due to mistakes in preparation and failures in the communication control test. The disadvantage is that the quality also deteriorates.

[Means to solve the problem]

The test method for the inter-note communication application software of the present invention is to create a transmission queue for other nodes for waiting for outgoing messages processed by the application software in the own node, and for waiting for received messages to be processed by the application software in the own node. an other-node reception queue for storing the response message corresponding to the transmission message; an other-node message file storing the response message corresponding to the transmission message; and m from the other-node transmission queue when testing inter-note communication.
Each node is characterized by having an inter-note communication simulator that reads the J transmitted messages, reads the corresponding response message from the other node message file, and outputs it to the other node reception queue.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention.

Then, the message is sent from external terminal 1 to communication line 1 via route ■.
It passes through the communication control device 2 and stays in the terminal reception queue 3 within its own node.

Next, the first message in the terminal reception queue 3 is notified to application software A via route ■, and application software A refers to and updates its own database 4 according to the program, and sends the message via route ■ to the other node transmission queue. be retained in.

In the operational state, sending software () B and receiving software () C are in operation, and the message is stored in the other node's reception queue 7 in another node via the communication control devices 2 and 6 and the communication line according to route (■), The application software D is notified by this.

Application software D references other databases 8,
The update is performed and the message is stored in the other note transmission queue 9 via route (3). Next, the message is stored in the other node reception queue 10 within the own node via the communication control devices 6 and 21 communication line via route (2), and is notified to the application software E via route (2).

Application software E references its own database 4,
The update is performed and the message is retained in the terminal transmission queue 11 via route (3). Next, the message is received by the external terminal l via the communication control device 222 communication line via the path O.

Next, the operation in the test state will be explained with reference to the drawings.

In the test state, transmitting software B and receiving software 77)C
does not operate, and inter-node communication simulator F operates.

In this case as well, the process is the same as in the operational state until the message is accumulated in the other note transmission queue 5, but then the message is not notified to other notes via route ■.
The notification is sent to the inter-no-F communication simulator F via route (3).

At this time, the inter-node communication simulator F reads the message in the other node transmission queue 5, reads the response message corresponding to the message from the other node message file 12 according to the preset conditions, and sends the response message via route ■. The received data is stored in the other node reception queue 10. Messages retained in the other note reception queue 10 are notified to the application software E via route (3).

〔Effect of the invention〕

As explained above, in the present invention, during the test state, the own node performs pseudo communication with other nodes, and at that time, the application software within the own node performs the same function as when performing inter-node communication. In addition, since the processing is only within the own notebook, there is no connection with hardware such as communication lines with other nodes, or with the other nodes themselves, so the application software within the own notebook is This has the effect of promoting efficiency in testing and increasing precision in terms of quality.

Claims (1)

[Scope of Claims] Another node transmission queue for waiting for transmission messages processed by application software within the own node; and another node reception queue for waiting for received messages to be processed by application software within the own node. and an other node message file that stores a response message corresponding to the transmitted message; and at the time of testing inter-node communication, the transmitted message is read from the other node transmission queue, and the corresponding response message is sent to the other node. A test method for inter-node communication application software, characterized in that each node has an inter-node communication simulator that reads from a message file and outputs it to the other node reception queue.
