Software testing is essential to minimize software problems. Recently, as the quality of software becomes more important, the software field is demanding more various and improved test methods. The reason is that as the embedded systems and software systems that test the software are changing from single to heterogeneous, the software is getting bigger.

Software testing is a very important step in improving software quality. About 30 to 60 percent of development costs are spent testing software.

Conventional software testing is the last step in the software development process, applying traditional methods of the software development life cycle. However, testing the software in the final stages can add extra cost to the development of the software and incur significant costs to fix the defects.

Therefore, the requirements of each stage of development should be analyzed in a way to minimize the additional costs incurred during the development stage of the software and to increase the reusability and extensibility of the outputs generated at each stage of development. It is necessary to design requirements separately from the design stage and extract test cases. In this sense, creating test cases based on requirements is a very important part of the test work that determines the quality of the software.

The conventional test case generation method simply generates a test case from source code of software. The conventional test case generation method has a problem that too many unnecessary test cases are generated because virtual data is used.

In addition, the conventional test case generation method has a problem in that it is not possible to substitute actual data, so that a user cannot obtain a test case to be verified.
