AutoPA: Automatic Prototyping from Requirements

We present AutoPA, a tool to analyze and validate the consistency and functional correctness of use case designs. The tool directly generates an executable prototype from the requirements. The requirements are captured from different views of the application. Each view is constructed as UML diagram annotated with OCL specifications. Based on a formal semantics, the tool is implemented so that both syntactic and semantic consistency among the provided views can be guaranteed. Afterwards the requirements are analyzed and translated into an executable prototype, allowing the user to interactively validate the functional properties of the requirements model. We illustrate the benefits of the tool using a real-world sized example.
