Further, input data from the terminal is set in the screen input data table 14 by the test control program 10. The screen processing programs 17 to 19 refer to this to check the validity of the input data and edit it into a storage format in a database or the like. In the screen control table 13, “next screen”, “previous screen”, “route change”, “redisplay”, “end”, etc., which are conditions for the test control program 10 to refer to the screen transition information table 12, are screen processing. Set by programs 17-19. The takeover data table 16 is an area for taking over common data between the screen processing programs 17 to 19 when the screen changes. In this case, a plurality of takeover data tables 16 may exist.
In order to realize screen transitions, an interface that enables connection between the integration test control program 10 and the transition determination program 11 and allows processing in one transition unit (multiple screen linkage that takes into account the processing order) is set. Yes.
Conventionally, tests have been carried out separately from the screen processing programs A, B, C... However, in the present invention, since the test control program 10 and the transition determination program 11 can be connected, the screen processing programs A, B, C ... can now be linked, and as a result, it has become possible to perform tests in conjunction with each other.
