A test input information search device searches for a candidate for test inputting in a database, and stores information of the database including a plurality of elements configured with a first structure, stores screen information including the plurality of elements configured with a second structure and displayed, identifies, from the second structure, relation between the elements in the plurality of elements included in the screen information, and searches for, based on the identified relation between the elements, the plurality of elements as the candidate for the test inputting from the information of the database.

Test input information search device and method

The present invention provides information for making a decision so as to efficiently localize environment-dependent portions of a program. Man-hours required to localize the environment-dependent portions are calculated by means of a unique method using program structure data and environment-dependent portions data. An effect of localizing the environment-dependent portions is calculated and visualized based on a Lorenz curve and a Gini coefficient.

Device, method, and program for visualizing dependent portions of program

Provided are a module division assistance device, a module division assistance method, and a module division assistance program for automatically extracting a divisible module by utilizing information relating to a function used by a module. A keyword obtaining unit of an information processing device collects data relating to a function used by a module into keyword use data organized by modules, and a data analysis unit uses the data and a calculation method for an indivisibility calculation item specified by a user and stored in an indivisibility calculation item list, thereby calculating an indivisibility, and stores the indivisibility into indivisibility data. Then, with respect to a module to be subjected to division determination, a module division determination unit compares the indivisibility relating to a function relevant to the indivisibility calculation item specified by the user with a threshold value stored in the indivisibility calculation item list, thereby determining whether the module can be divided or not.

Module division assistance device, module division assistance method, and module division assistance program

A data visualization device includes a module for a specific viewpoint which is selected and a diagram representing the program is generated for modules included in source code. For a module extracted using a module call relationship diagram creation unit, a data analysis unit calculates the relevance of a viewpoint, which is input by a user, by utilizing a module call relationship and a common data usage relationship. The relevance is calculated by multiplying the viewpoint relevance of a viewpoint dependent module serving as the base point and a viewpoint relevance weight in an action determination table and in inter-module path viewpoint relevance weight data. The calculated viewpoint relevance is corrected using a viewpoint relevance correction value in viewpoint relevance determination noise correction threshold data. Final viewpoint relevance is stored into per-module viewpoint relevance determination data and a program diagram in accordance with this viewpoint relevance is created.
