Abstract

PURPOSE:To execute a program test with high efficiency in an on-line system by generating a test data different from the sample test data as an input data needed for a program test. CONSTITUTION:The input/output processing and the internal processing of a program are connected to each other by an input/output data via a waiting cue. Therefore, a means which outputs the control to a test data generating program 10 is incorporated to an execution control program 1. When the control is outputted to the program 10, the input data for the start of internal processing program is extracted from a cue 5 and stored temporarily to an input data buffer 11. Then the external conditions, i.e., the type, class, store position, etc. of a terminal device which are set to the input data are transferred to other external conditions, etc. to be set to the input data. These external conditions are stored temporarily to an input data buffer 12 when necessary. Then another input data is registered to the cue 5 waiting for the start of internal processing program as a different test data.

Next, the test I-theta generation process according to the present invention will be explained. First of all, the internal processing that is edited by the above-mentioned manual processing (internal processing)!11. ° - It consists of screw types, etc., and the test of this online program is (
There are some methods that are carried out by changing the %4Zl: and others that are carried out by changing the Leavis type without changing the external conditions, and usually all combinations of the two are carried out. Therefore, according to the present invention, by utilizing the fact that the input/output processing of the program and the internal processing 1 are connected by input/output data via a waiting queue, the execution control grossim 1 starts up /2. The input/output processing program 2 detects a request to the system, registers the input data for starting the internal processing program in the internal processing program startup queue 5, and then returns control to the execution control program 1 after /ξ. A means for controlling the test data generation program 10 is incorporated into the execution control program 1. In this way, the test data generation program 10 is executed in the execution control program A1.
The input data for starting the internal processing program is extracted from the input data bath sofa 11 and temporarily stored at °C. After transferring it to another test condition, etc., setting it as nuclear input data, and temporarily storing it in the human data buffer 112 as necessary, do you want to use this other input data as different test data? S1: Register in queue 5 waiting for processing program to start. In this case, the input data of one animal can be used as sample test data by preparing various external conditions etc. for transfer. It becomes possible to generate a plurality of different input data as test data from the input data. After that, when the execution control program 1 returns control from the test data generation program 10, it is possible to start the process from the point after passing control to the test data generation program 10. The processing program 2 is activated and a test of the program is executed using the test data, and a series of subsequent system operations are performed normally.
