Abstract: A test data generation device configured to generate test data of a test related to screen transitions provided by a web application, the test data generation device including a selection reception unit configured to receive selection of one or more screen transitions among the screen transitions; an extraction unit configured to extract a constraint from a source code of the web application by analyzing the source code by using a description specification of a constraint set or defined by a framework of the web application; and a generation unit configured to generate a plurality of test data that cover test standpoints of equivalence partitioning and boundary value analysis by using the constraint of an input form included in a screen of a transition source of the one or more screen transitions that are selected.

Abstract: A screen discrimination device includes: a determination section which executes an automatic operation of a displayed screen of an application to cause screen transition to occur, and determines whether or not each screen at a transition destination is different from each post-transition screen based on a predetermined method; a reception section which outputs a result of the determination of whether or not each screen at the transition destination is different from each post-transition screen, and receives input of a condition for identifying a screen serving as a correction target based on the result of the determination; and a re-determination section which re-executes the automatic operation of the displayed screen of the application to cause the screen transition to occur, determines whether or not each screen at the transition destination meets the condition and, in a case where a first screen meeting the condition is present, when the post-transition screen includes a second screen meeting the conditio
