DEVICE, METHOD AND PROGRAM FOR GENERATING DATA FOR TEST HAVING PLURAL REFERENCE ACCESS IN TEST PATH

摘要

PROBLEM TO BE SOLVED: To enable generation of test cases to which subsequent SELECT sentences are executed in accordance with the number of records as reference results of a plurality of times of reference of SELECT sentences, and to reduce the number of replacement of DB initial state at the time of executing a test.SOLUTION: A test case is extracted from input design information; test cases which can share the same initial state of a DB are subjected to grouping as a test case group in such a manner that records, extracted out of test cases belonging to the same group by means of respective SELECT sentences, do not overlap; information of each test case in the test case group is acquired; a constraint equation for an input variable of the test case is generated; the number of records is set for each DB table to be finally generated; it is determined where records hit by each reference query are disposed; and it is reflected to a test case group. A constraint equation of a test case group is solved with an arbitrary solution method so as to output an input value and a DB initial state for each test case.
