Abstract

An example of the invention is a test support system for supporting testing of a function of a program that works depending on a position of a mobile object in map information. A storage device holds event generation requirements information defining requirements for generation of an event in the program. The requirements specify a position designated in the map information and requirements on movement of the mobile object with respect to the designated position. A processor creates a plurality of test cases to be referred to in creating test data to be input to the program for checking whether the event is generated in accordance with the requirements with reference to the map information and the requirements. Each of the plurality of test cases specifies the designated position in the map information and movement of the mobile object with respect to the designated position.
