USING TEST ORACLES AND FORMAL SPECIFICATIONS WITH TEST-DRIVEN DEVELOPMENT
Shadi G. Alawneh, Dennis K. Peters · International Journal of Software Engineering and Knowledge Engineering · 2013
This paper illustrates how Test Oracles and Formal Specifications, with appropriate tool support, can be used with Test-Driven Development (TDD). In TDD, the test code is a formal documentation of the required behavior of the component or system that is being developed, but this documentation is necessarily incomplete and often over-specific. We describe an alternative approach to TDD that is to develop the specification of the required behavior in a formal notation as a part of the TDD process and to generate test oracles from that specification. We present the results of using this approach to develop programs used in a project at the Faculty of Engineering and Applied Science at Memorial University.
