Automatic Generation of UTP Models from Requirements in Natural Language

Unified Modeling Language (UML) is the language of modeling from requirements for software design. UML Testing Profile (UTP) is the definition of the modeling test from requirements analysis for software testing. UTP has Test Architecture, Test Behavior, Test Data, and Time Concepts as the test models. Requirements are described in natural language, and engineers who have modeling skills then manually generate test models. Hence the generation of test models depends upon the engineer's skills, leaving the quality of test models unstable. In this paper, we present automatic generation test models from requirements in natural language by focusing on descriptions of test cases in UTP test behavior. We develop three rules to generate test models from requirements by using natural language processing techniques and experiment with our approach on requirements in language that is considered natural English. Our results in three case studies show the promise of our approach.
