Unit Testing Techniques and Tool Support

This paper describes a tool developed at Pi Technology for performing unit testing. The tool is used to support the production of embedded real-time software for high-reliability applications such as engine control units. A brief history of the development of the tool is given along with details of how the tool is used in the context of our development process. The tool itself is examined from both usage and construction points of view and an analysis of the tools effectiveness in use is given.
