Abstract: A document file is displayed on a display device. A first display unit, which is a unit in which the document file is displayed, is divided into a plurality of areas. From the plurality of areas obtained by dividing the first display unit, a first target area viewed by a viewer is identified. In response to the first target area being displayed on the display device shifting from the first display unit to a second display unit, a decision is made whether to use setting information from the display area when the first target area identified by the identification means is displayed, based on a structure of the first display unit and a structure of the second display unit.

Abstract: Testing of a computer program product by selecting a test node at which a snapshot is to be acquired to enable the completion of tests along test scenarios in the shortest time is provided. Information on a test scenario, information on a test node to which a test node makes a next transition, and other information are stored. For each test node, it is determined whether a branch path exists, and for each of these test nodes, an estimated execution time required to complete a test when a snapshot is acquired at a test node is calculated, an execution time required to complete a test without acquiring any snapshot is calculated, and a difference between the execution time and the estimated execution time is calculated as a reduced time. A test node with the longest reduced time is selected, and information for identifying the selected test node is output.
