Automatic Test Case Generation Using Use Case Diagram

A new model based approach for automated generation of test cases in object oriented system has been presented. The test cases are derived by analyzing the dynamic behavior of the object due to internal and external stimuli. The scope of the paper has been limited to the use case diagram taken from the Unified modeling Language model of the system. Intelligent searching techniques have been developed in order to provide a solution to the issue of finding information relevant to the user needs, and the problem of information overload - when far too much information is returned from a search. We employ this technique to introduce an automatic tool which used to generate the test cases automatically according to the system’s requirement. The tool uses two steps for generating test cases. First, the system’s requirements are transformed into a Unified Modeling Language (UML) Use-case Diagram. Second, the test cases will be automatic generated according to the use cases respectively. In the workspace, the Toolbox is used in order to ease the drawing of the use-case diagram.
