Simulation is one of the software development techniques that includes interactive graphic display on the human-computer interface to improve the development and productivity of the system. Therefore, it has the advantage that the performance of the program can be reviewed before the software is distributed to consumers. This simulation technique can be simulated in various environments, such as embedded systems or large systems, before testing its functionality. Specialized features of the simulation allow you to set operating breakpoints or instruction breakpoints that allow the execution of a program to stop at a critical moment, as well as to track the progress of the program.

Software testing, which has grown rapidly since the 1990s, is affecting the overall software and IT industries.

A profiling step, a mapping step of converting the verified test case into simulation program code in a state that can be simulated with reference to the user environment profiling information, and a real or virtual test using the simulation program code. It provides a simulation method that supports testing of the software under test based on the user environment profiling, which includes the simulation step of executing the simulation in the test environment.

The test case generating step may include an input step of receiving a flow chart and a state chart of the test target software, the number of possible flow cases in the flow chart and the number of possible state transitions in the state chart.
