Abstract

PURPOSE:To execute the test of a test system program independently of an execution program in operating at one-line real time by providing the titled device with an input data processor connected between a computer and an external apparatus to inform data inputted from an input apparatus to a prescribed program and an output data processor for outputting output data outputted from the program to a prescribed output apparatus. CONSTITUTION:The input data processor 2 informs data inputted from the external input apparatus 1 to a program requiring the data in accordance with selecting status stored in an input selection memory built in the processor 2 itself. The input selection memory stores the connecting status between the external input apparatus 1 and the program and is enabled to inform input data simultaneously to a program in a system to be tested and a program in the executing system. The output data processor 3 can set up the selection memory so as to output the output of the program to plural apparatuses, so that output from the program to plural apparatus can be attained only by one output and the program can be simplified.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides input/output data for controlling input/output data to an external input/output device in order to test a computer program online. It relates to a processing device.

(Prior Art) Conventionally, it has been impossible to test a production program running in a single computer online. (A "program" is a group of programs that have the same purpose. All the following are the same.) This is because in order for one production program to coexist as a test program, ,
Input data to those programs is input from the same resource.

This is because the output data of the test program must be output to an alternative device that can confirm the test results, rather than to the external device output by the production program.

(Problem to be solved by the invention) However, physically the same input data is input from the same resource within one computer, the test program is run in the same form as the production program, and the output data is It was difficult to output to different devices due to the hardware configuration. Another problem was that they were not equipped with equipment to prevent test programs from interfering with production programs.

These problems are not limited to production-based programs and test-based programs, but the same can be said of several different production-based programs that require the same input data.

SUMMARY OF THE INVENTION An object of the present invention is to provide an input/output data processing device that can test a test program independently of a real program running online in real time.

[Structure of the invention]

(Means for Solving Problems) When a computer performs some input/output with an external input/output device, the present invention exists between the computer and the external device, and stores data input from the input device in a predetermined manner. It is characterized by having a configuration consisting of an input data processing device that notifies the program, and an output data processing device that outputs output data output from the program to a predetermined output device.

(Function) With this configuration, it is possible to test the same program while the program is running online.

(Embodiment) FIG. 1 shows an embodiment of an input data processing device and an output data processing device according to the present invention.

In order to achieve the above object, an input data processing device and an output data processing device of the present invention are placed between a program and an external input/output device during input/output. Reference numerals 1 and 5 are external input and output devices, which mainly include process input/output devices, data transmission devices, CRTs, typewriters, data files, and the like. Reference numeral 2 denotes an input data processing device that once receives input from an external input device and notifies the necessary program. 3 is an output data processing device that once receives the output from the program and outputs it to a necessary external device. 4 is a program consisting of one or more programs.

FIG. 2 is an explanatory diagram of the input data processing device.

The input data processing device notifies the necessary program of data input from an external input device according to the selection state stored in an internal input selection memory. The input selection memory is a memory that stores connection states between external input devices and programs. This makes it possible to simultaneously notify input data to the program under test and to the production program, and allows input data to be passed to the test program without changing the production program. Program testing can be made easier. Furthermore, a test program can be configured to provide the actual program and the input data to check its own functions by setting this selection memory. FIG. 3 is a functional flowchart of the input data processing device.

FIG. 4 is an explanatory diagram of the output data processing device.

The output data processing device switches and outputs the data output by each program to a necessary external device according to the selection state stored in an internal output selection memory.

This output selection memory is a memory that stores the connection status between the program and external output equipment. As a result, the output of the production program can be output to the external device that was originally output, and the output of the test program can be set in the selected memory as an external alternative output device that can check the test results instead of the device that originally output it. It becomes possible.

FIG. 5 is a functional flowchart of the output data processing device.

The output data processing device can set the selection memory to output the output from the program to multiple devices, so when outputting from the program to multiple devices, only one output is required, simplifying the program. be able to.

〔Effect of the invention〕

According to the present invention, although conventionally a test program computer was required in addition to a production program computer,
Since a production program and a test program can coexist within one computer, a computer for the test program is not required. In addition, even if multiple types of production programs are mixed on one computer, input data from one external input device can be notified to multiple production programs, and the same effect can be achieved. .
