Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for testing an online system, and more particularly, from a terminal device of an online system that executes processing in a distributed manner between a host processing device and a terminal device. When the same inquiry is performed from a plurality of terminal devices in an online system in which the terminal device transmits inquiry information by key input data from the terminal device side and receives response information from the host processing device to the terminal device, The present invention relates to a test method for verifying the consistency of response information transmitted from the host processing device to each terminal device as the response.

[Conventional technology]

2. Description of the Related Art Conventionally, when a computer system such as an online system is constructed and operated, a system operation test of a hardware device, a software program operation test, and the like are performed in various forms, and test results are verified. In such a system verification, a functional test is finally performed with the system actually operating. In addition, when a function is added to the system, or when a program is modified to change the system, it must be verified whether the existing function operates normally as it is. For example, as in the "program inspection method" described in Japanese Patent Application Laid-Open No. 61-34640, in remodeling a program, it is necessary to verify whether the conventional function is satisfied as it is. An inspection is performed to check the test results of the program and the modified program.

On the other hand, even when the system configuration other than the program is changed, it is necessary to confirm the operation of the existing functions, including the operation test of the hardware device. For example, in an online system, before the change, a system configuration in which processing is performed by a central processing unit directly connected from the terminal control device is used. For example, when the system configuration is changed so that processing is performed by the user, it is necessary to confirm the consistency of existing functions.

However, in the above-described program inspection method of the related art, although the change of the system configuration other than the program and the function are the same, no consideration is given to checking the consistency of the existing functions by changing the processing method, and It is not possible to verify the test results when changing and when changing the processing method.

Here, no consideration is given to a method relating to the input processing of test data, and when the amount of test data is large, the input work requires a lot of man-hours. With regard to the input of test data to be compared, if there is a large amount of data to be input, a function of automatically simulating and inputting may be provided, but in order to obtain the data to be compared,
A more extensive test must be performed using an input method that collects the manually input portion of the terminal device into the pseudo device and performs the test.

As a method for solving this problem, for example,
There is an "on-line test method" disclosed in Japanese Patent Application No. 217936.

According to this online test method, communication scenario data, which is a test program, is created in advance on the host computer, and when a test scenario transfer is instructed from each workstation as a terminal device, communication from the host computer is performed. The scenario data and the test start time are transferred to the workstation, and when the test start time comes, the test start means of each workstation starts the test based on the communication scenario data.

After the start of the test, the test execution means sequentially transmits the test scenario to the host computer, and registers data transmitted from the host computer as a response as a file on the workstation.

Thereafter, the test result determination means transfers the file from the workstation to the host computer, and compares the file with predicted response data previously created in the host computer,
Determine if there are any illegal parts in the online program.

[Problems to be solved by the invention]

However, the “on-line test method” disclosed in Japanese Patent Application Laid-Open No. 2-217936 includes a processing system for realizing a process performed on inquiry information output from a terminal device, that is, a host processing device and each terminal. No technical means has been disclosed for verifying whether the functions realized by the different processing systems, that is, the processes, are the same when the connection form with the device is different.

Therefore, when the connection form between the host processing device and each terminal device is different, there is a problem that it is not possible to verify whether the functions realized by the different processing systems, that is, the processes, are the same.

For example, processing that was conventionally performed only by the program in the host processing device is distributed to the host processing device, the terminal control device, and the terminal device without changing the processing content. When dispersing or downsizing is performed, the terminal device generally bears a part of the processing, and accordingly, the program of the terminal device is also changed.

On the other hand, in the "on-line test method" disclosed in Japanese Patent Application Laid-Open No. 2-217936, a test program, that is, test scenario data transferred from a host processing device to a workstation, which is a terminal device, before executing a test is described above. Thus, it is the data of the processing result performed by the terminal device itself.

Therefore, when the program of the terminal device is changed by distributing the load or downsizing of the host processing device, there is a problem that the test scenario data must be changed and verified.

In the "online test method" disclosed in Japanese Patent Application Laid-Open No. 2-217936, it is necessary to prepare communication scenario data, which is a test program corresponding to each terminal device, on the host computer. When different types of terminal devices are connected to the online system, even if the test contents are the same, communication scenario data corresponding to the terminal device model, that is, a test program must be created on the host processing device. There was a problem that I had to put it.

The present invention has been made to solve the above problems.

An object of the present invention is to easily determine whether functions realized by the same processing match regardless of a difference in output of a terminal device due to a difference in connection between the host processing device and the terminal device. An object of the present invention is to provide a test method of an online system that can be verified.

Another object of the present invention is to provide an online system,
Even when the connection configuration between the host processing unit and the terminal device is changed due to load distribution or downsizing of the host processing unit, the test data and test procedure are realized before and after the change. It is an object of the present invention to provide an on-line system test method capable of easily verifying whether or not the functions performed match.

[Means for solving the problem]

The outline of a typical invention disclosed in the present application is briefly described as follows.

(1) A host processing device, a first terminal device connected to the host processing device in a first mode, and a second terminal device connected to the host processing device in a second mode different from the first mode. And performs a predetermined process for an inquiry output from the first and second terminal devices, and responds to the first and second terminal devices as a result of the predetermined process. An online system test method configured to return information, wherein the host processing device converts test data created in advance into key input data and transfers the key input data to the first and second terminal devices. Outputting the inquiry information based on the key input data received by the first and second terminal devices; and outputting the inquiry information output by the first and second terminal devices. Receiving response information that is a processing result for a report, the first and second terminal devices respectively transferring the response information to the host processing device, and the host processing device transmitting the response information to the first terminal device. Comparing the response information transferred from the second terminal device with the response information transferred from the second terminal device, and outputting the comparison result to a predetermined device.

(2) In the online system test method according to (1), the host processing device transmits the key input data to the second system via a second signal path different from the first signal path constituting the online system. Transfer to the first and second terminal devices.

(3) In the online system test method according to the above (1) or (2), the host processing device may give the same key input data to the first and second terminal devices, and Verify the identity of the response information.

[Action]

According to the above-mentioned means (1) to (3), when the test data prepared in advance in the host processing device is transferred to the first and second terminal devices, the data is converted into key input data,
The first and second terminal devices execute predetermined processing based on the key input data as input from the input device connected to each of the key input data and output inquiry information, thereby providing different connection modes. It is possible to cause the first and second terminal devices to execute processing based on the key input data obtained by converting the test data, without depending on certain first and second connection forms.

On the other hand, the response information obtained by the first and second terminal devices is collected by the first and second host processing devices, and then compared with the response information and output to a predetermined device, so that different connection information is obtained. The processing results obtained by the first and second terminal devices can be determined without depending on the first and second connection modes.

Therefore, in the test method of the online system according to the present invention, the first and second connection modes are different, that is, the assignment of the processes assigned to the first and second terminal devices is different, so that the terminal device has a different connection form. Even when the outputs are different, the operation and effect can be easily verified as to whether or not the functions realized by the predetermined processing are the same.

Further, even when the connection modes of the first and second terminal devices are different, if the processing contents are the same,
Since it is possible to easily verify whether or not the functions realized by the processing match, for example, a new intermediate processing device is added between the host processing device and the terminal device of the existing online system, and this intermediate processing is performed. When a device has a processing program for sharing a part of the processing, and the host processing device, the intermediate processing device, and the terminal device execute the existing processing, the load distribution of the host processing device can be reduced. Even if the hardware configuration and the program configuration (software configuration) of the online system are changed without changing the function realized by the predetermined processing for downsizing or the like, the test data and the test procedure are changed. Thus, it is possible to easily verify whether or not the functions realized before and after the change are the same.

Further, since it is not necessary to change the test data, even if the hardware or software configuration of the online system is changed as described above, for example, the response information before the change is stored in the host information processing device. In this case, it is possible to verify that there is no change in the function realized by the online system only by an easy method of storing the file as a file and comparing it with the response information of the test performed after the change.

〔Example〕

Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an online system according to one embodiment of the present invention. In FIG.
1 is a central processing unit, 2 is a terminal control computer, 3 is a first terminal control device, 4 is a first terminal device, 5 is a first display input device, 6 is a simulator, and 7 is a key generated by the simulator 6. Input data (text data of inquiry information), 8 is a second terminal control device, 9 is a second terminal device,
Reference numeral 10 denotes a second display input device. Reference numeral 11 denotes a first test signal line connected from the simulator 6 to the terminal device 4, and reference numeral 12 denotes a second test signal line connected from the simulator 6 to the terminal device 9.

In the online system, a first terminal device 4 is connected via a first terminal control device 3 to a central processing device 1 and a terminal control computer 2 that perform host processing as a host processing device, and also performs host processing. Central processing unit 1
A second terminal device 9 is directly connected via a second terminal control device 8 to a system configuration. The terminal control computer 2 is a processing device that performs a part of the host processing, and is a device that does not need to be interposed. In this system configuration, the load on the central processing unit 1 is reduced.
It is provided to improve the response performance corresponding to the first terminal device 4. Accordingly, in the system configuration here, the host processing for the first terminal device 4 is performed by the central processing unit 1 and the terminal control computer 2, and the host processing for the second terminal device 9 is performed by the central processing unit 1
Performs processing directly.

As described above, in an online system to which a plurality of terminal devices are connected, host processing for each terminal device is performed by a different hardware depending on a signal path to which the terminal device is connected due to a difference in system configuration or a change in system configuration. May be performed by the device. For this reason, when the terminal device is newly connected to the system and the system is changed, the test result of the system operation must be verified in the actual operating state of the system. In the online system of this example, verification of the test result of the system operation is performed under the control of the simulator 6.

Simulator 6 provided inside central processing unit 1
Is a first test signal line between the first terminal device 4 and the second terminal device 9 to be tested.
11 and a second test signal line 12.
The simulator 6 has key input data (query code) 7 corresponding to key input operation data in each terminal device stored on its own test data table (not shown).
Is read one data at a time, and the key input data is simultaneously sent to the first terminal device 4 and the second terminal device 9 to be tested via the first test signal line 11 and the second test signal line 12, respectively. 7 is transmitted.

The test key input data 7 is transmitted to the first test signal line.
The first terminal device 4 received via the terminal 11 operates as if there was a manual key input by an operator operation.
The key input data 7 is transmitted (inquired) to the central processing unit 1 and the terminal control computer 2 that perform the host processing via the first terminal control unit 3. Thereby, the central processing unit 1 and the terminal control computer 2 perform a response process based on the data received from the first terminal device 4, create response information of the screen display information, and perform the first
The response information (screen display information) is transmitted to the first terminal device 4 via the terminal control device 3. Upon receiving the response information, the first terminal device 4 creates screen display information based on the response information, stores the screen display information in the screen display buffer, and displays the information on the display screen of the display input device 5. At this time, the first terminal device 4 communicates with the simulator 6 via the first test signal line 11 to receive response information.

The simulator 6 having received the reception notification issues a READ command to the first terminal device 4 after the reception notification,
An instruction to read screen display information (response information) stored inside the first terminal device 4 is transmitted. This allows
The first terminal device 4 transmits the screen display information (response information) to the simulator 6 via the first test signal line 11 as it is.

The simulator 6 outputs and stores the screen display information (response information) received from the first terminal device in a response information data file for each test signal line (for each terminal device to be tested), and later stores the response information data file. Is compared with a reference value. After the above processing is completed for one text (inquiry code; key input data), the same processing is performed for the text to be the next test data.
This processing is repeated until the processing for the text of the last test data stored in the test data table is completed.

However, the reference value described above is received by the corresponding terminal device as a result of host processing (response processing) of a normally operating online system in response to key input data transmitted from the simulator 6 to each terminal device. This is the screen display information of the response information to be performed.

Therefore, the reference value is calculated in advance by the simulator 6, for example, and the result is stored in a reference value data storage buffer (not shown) or the like.

Next, at the time of comparison, the simulator 6 reads this reference value from the reference value data storage buffer, and
By comparing with the screen display information obtained from 4,9,
Can test.

Also, it goes without saying that the simulator 6 may calculate the reference value when comparing the screen display information obtained from each of the terminal devices 4 and 9 with the reference value.

In addition, the process performed by the simulator to provide the text of the test data to the terminal device and collect the screen display information of the response information is the same for the other terminal devices connected to the online system, that is, the second terminal device 9. To do. The same processing is performed on the second terminal device 9 using the second test signal line 12. Second terminal device 9
Is performed by the simulator 6 using the second test signal line 12 at the same time as the processing for the first terminal device 4 described above, and the response information of the second terminal device 9 to the text of the test data is obtained. A process of collecting image display information into a response information data file is performed, and the data in the response information data file is compared with a reference value later. The second terminal device 9 is directly connected to the central processing unit 1 via the terminal control device 8, and host processing is performed solely by the central processing unit 1. Therefore, the response information to the second terminal device 9 is created by the central processing unit 1 from the key input data of the text, and is returned to the second terminal device 9 via the second terminal control device 8. . As a result, the difference in the system configuration of the host processing device with respect to each terminal device in the online system is that the test data input from each terminal device and the test result of the response information received by the terminal device are verified. Is reflected in the test result.

FIG. 2 is a block diagram of a main part showing an internal configuration of the terminal device. 2, reference numeral 21 denotes a terminal device, 22 denotes a first data transmitting / receiving circuit, 23 denotes a second data receiving circuit, 24 denotes a first data storage buffer, 25 denotes a second data storage buffer, and 26 denotes a microprocessor. , 27 are a screen display buffer, 28 is a display control circuit, and 29 is a display input device. Here, the terminal device 21 performs a test process in addition to the first data transmission / reception circuit 22 and the first data storage buffer 24 of the original signal path for connection with the host processing device of the online system. A second data transmission / reception circuit 23 and a second data storage buffer 25 are provided as signal paths for connection with a simulator to be performed. The first data transmission / reception circuit 22 is connected to the microprocessor 26 via a first data storage buffer 24, and the second data transmission / reception circuit 23 is connected to the microprocessor 26 via a second data storage buffer 25. Is done. Microprocessor
The 26 performs overall processing and control of the terminal device, and controls the display input device 29 via the image display buffer 27 and the display control circuit 28.

Second data transmission / reception circuit 23 provided in terminal device 21
Is connected to a test signal line connected to the simulator. Test data from the simulator is received by the second data transmission / reception circuit 23 and stored in the second data storage buffer 25. When the test data is stored in the second data storage buffer 25, the microprocessor 26
The test data stored in the data storage buffer 25 is converted into the format of key input data manually input to the terminal device 21 and stored in the screen display buffer 27. The key input data stored in the screen display buffer 27 is transmitted to the terminal control device through the first data transmission / reception circuit 22 via the first data storage buffer 24 under the transmission control of the microprocessor 26. As a result, the obtained response information from the terminal control device is passed through the first data transmission / reception circuit 22,
The data is stored in the first data storage buffer 24. The response information data stored in the first data storage buffer 24 is converted into screen display information in a data format to be displayed on the screen by the microprocessor 26, stored in the screen display buffer 27, and transmitted through the display control circuit 28. Is displayed on the display screen of the display input device 29. At the same time, the second data storage buffer 25
Then, the reception of the response information is notified to the simulator through the path of the second data transmission / reception circuit 23. Thereafter, in response to the reception notification, the simulator collects the response information, and when the simulator issues a READ command, the microphone processor 26 of the terminal device 21 stores the READ command in the screen display buffer 27. The screen display information is transmitted to the simulator via the second data storage buffer 25 and the second data transmission / reception circuit 23.

FIG. 3 is a flowchart showing a test result verification process of a terminal device of an online system by a simulator.

In this test result verification process, first, in step 30, it is determined whether or not there is unprocessed text data of test data. If there is no unprocessed data, the process ends. If there is unprocessed data, the process proceeds to step 31 to send one test data to the terminal device. Upon receiving the test data in step 32, the terminal device makes an inquiry to the host in step 33 using the test data as key input data. Next, when response information is received from the host in step 34, screen display information is created based on the response information in the next step 35. Next, in step 36, completion of creation of screen display information is transmitted to the simulator side.
On the simulator side, in response to this, in step 37,
Receiving the completion of the creation of the screen display information by receiving the response information from the terminal device, and then in step 38, the terminal device
Issue an AD command. Thereby, the terminal device transmits the screen display information to the simulator in step 39. The simulator receives the data transmission from the terminal device side, receives the screen display information of the response information in step 40, and outputs it to the response information data file. Then, the process returns to step 30 again to determine whether there is any unprocessed data, and repeats the processing from step 31 until there is no unprocessed data.

FIG. 4 is a block diagram showing a processing flow for comparing response information data collected by the simulator.

In the online system, the simulator sets key input data of test data in the terminal device, collects response information from the host processing device, stores it in the response information data file 13, and then stores the response information in the response information data file 13. The data is classified into test signal lines (terminal units) and divided into a # 0 data file 14 and a # 1 data file 15 for response information comparison. Next divided # 0
The data file 14 and the # 1 data file 15 are compared by the compare program 16, and the mismatch information is output as a compare result list 17.

In this way, since the test results are verified by the simulator, the key data of the test data can be given and input from any terminal device without depending on the device configuration from the terminal device to the central processing unit, and the terminal device side can input the key data. The key input data can be sent to the central processing unit, and the result of the information responded to each terminal device can be verified.

Further, for example, when a result indicating that the divided # 0 data file 14 and the # 1 data file 15 do not match is output to the compare result list 17, the mismatched portion and the corresponding reference value described above are output. The test result can be verified by comparing the test result with the test result. Further, the test result may be verified by referring to the divided data file and performing the determination.

Further, when four or more terminal devices are connected, three compare results are obtained in the compare result list 17, and when one terminal device has an abnormality, the compare result is displayed. Needless to say, it can be easily specified from the result list 17.

FIG. 5 is a diagram showing an example of the configuration of another online system for performing verification processing of test results by a simulator provided in the central processing unit. In FIG. 5, 1 is a central processing unit, and 6 is a simulator. The simulator 6 generates key input data (text data of inquiry information) 7 and sends out the terminal device for testing the system operation via the test signal lines 11 and 12. These are the same as those described with reference to FIG. 1, but the terminal device 52 connected to the online system here is of a cluster type and is connected to the central processing unit 1 via the terminal control device 51. Have been. In another embodiment, the terminal device 54 connected to the online system is of a stand-alone type, and is directly connected to the central processing unit 1. The terminal device
A display input device 53 and a display input device 55 are connected to the terminal 52 and the terminal device 54, respectively.

As described above, in the online system in which a plurality of terminal devices are connected in various different forms, the simulator 6 is connected to the online system by the simulator 6 irrespective of the form in which the host processing for each terminal device is processed by the central processing unit. A test result verification process of providing key input data of test data to each terminal device and verifying each response information of a host process (processing of the central processing unit) responding to a pseudo key input operation from each terminal device is performed. I can do it.

As described above, the test result verification processing of the system operation of the online system according to the present embodiment has the following effects.

(1) Conventionally, a human can perform test data input and test result collation by a simulator.
The efficiency of test work and verification of test results can be improved.

(2) Since the test can be performed from any terminal device without depending on the device configuration from the terminal device to the central processing unit, the consistency of the response information responded to each terminal device is verified in a real environment. it can.

(3) The system operation can automatically realize not only the confirmation of the existing functions due to the modification and modification of the program but also the consistency of the existing functions due to the configuration change and the change of the processing method.

(4) By inputting test data to the terminal device and comparing the screen display information created in each terminal device as a result, if the screen display information is finally the same, the processing steps up to that point ( Even if the processing methods and data contents are different, the test can be performed without being aware of the difference.

As mentioned above, although the present invention was explained concretely based on an example, the present invention is not limited to the above-mentioned example.
It goes without saying that various changes can be made without departing from the scope of the invention.

〔The invention's effect〕

The effect obtained by the representative one of the inventions disclosed in the present application will be briefly described as follows.

(1) In an online system, it is easy to determine whether or not the functions realized by the same processing are the same, regardless of the difference in the output of the terminal device due to the difference in the connection form between the host processing device and the terminal device. Can be verified.

(2) In an online system, test data and test procedures are changed even when the connection mode between the host processing device and the terminal device is changed due to load distribution or downsizing of the host processing device. It can be easily verified whether the functions realized before and after the change match.
