Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test cases are manually created by specialists, then test case quality is maintained, but productivity deteriorates and time consumption increases
Solution Approach 1:
The system enables self-service test case generation by automatically extracting test determination elements from use case specifications and generating test cases without requiring specialist intervention. The automated extraction unit identifies relevant elements from natural language descriptions, and the generation unit creates test cases based on these elements, allowing non-specialists to generate quality test cases independently.
Solution Approach 2:
The patent introduces an intermediary automated extraction and generation system that bridges the gap between use case specifications and test cases. This intermediary process automatically translates natural language requirements into structured test determination elements and subsequently into test cases, eliminating the need for manual specialist intervention while maintaining quality.
2Productivity
If test cases are manually created by laymen, then productivity is maintained, but test case quality degrades and time consumption increases
Solution Approach 1:
The system empowers laymen to generate quality test cases through self-service automation. The automated extraction unit handles the complex task of identifying test determination elements from use case specifications, and the generation unit automatically creates test cases, enabling non-specialists to produce high-quality test cases without manual expertise.
Solution Approach 2:
The patent replaces the mechanical manual process of test case creation with an automated computational system. The automated extraction and generation units substitute human cognitive processes with algorithmic operations, eliminating the quality degradation associated with manual creation by laymen while maintaining high productivity.
3Ease of operation
If all test case tasks are performed manually, then flexibility is maintained, but productivity deteriorates
Solution Approach 1:
The patent segments the test case generation process into distinct automated units: extraction unit for identifying test determination elements and generation unit for creating test cases. This segmentation allows each unit to perform its specific function efficiently while maintaining overall process flexibility through the modular architecture.
Solution Approach 2:
The system performs preliminary automated extraction of test determination elements from use case specifications before test case generation. This preliminary action prepares structured data that facilitates efficient subsequent generation, improving overall productivity while maintaining flexibility through the two-stage automated process.

AI summary
In the program for generating a test case based on a use case diagram and the method for generating a test case using the same according to exemplary embodiments of the present invention, since a use case specification specifying a procedure or method scenario performed in a use case diagram is used to complement insufficient information of a use case diagram used to extract a test case, a layer, although he is not a specialist or an expert, can easily generate a certain level of a test case to effectively perform a test. Thus, requirements can be verified in advance by generating a test case from a use case program, reducing the costs for a system development.
