1. An apparatus for generating a test script for automatic test execution tools that executes a script where actions to a GUI object for accepting an input operation are described, that searches for the GUI object at the time of execution, and that execute a software test, displayed on a display screen on a computer, having: a specification file storage section for storing a specification file where functional specifications of software including the GUI object are described according to a standardized description method; and a property file storage section for storing a property file that maps input variable names of input variables described in the specification file and object type names; wherein the apparatus comprises: an input/output variable extracting section for analyzing data of the specification file stored in the specification file storage section based upon the description method, and for extracting an input variable and an output variable per processing of analyzed and extracted display screen; and a test-script generating section for generating a test script file including the test script, which is the test script that searches for the property file based upon the input variable name of the input variable extracted by the input/output variable extraction section; acquires an object type name mapped by the searched input variable name; and is expressed using the acquired object type name and input variable name, and which includes the test script for searching the GUI object corresponding to the input variable from the display screen where the automatic test execution tools are displayed at the time of test execution, and the test script for comparing a value, which is a value corresponding to the output variable extracted by the input/output variable extraction section, and which is displayed on the display screen at the time of test execution, with an expected value separated entered by corresponding to the output variable by the automatic test execution tools.
