Specification-based (or functional) testing enables us to detect errors in the implementation of functions defined in specifications, but since specifications are often incomplete in practice for some reasons (e.g., lack of ideas, no time to write), it is unlikely to be sufficient for testing all parts of corresponding programs. On the other hand, implementation-based (or structural) testing focuses on the examination of program structures. which allows us to test all parts of the programs, but may not be effective to show whether the programs properly implement the corresponding specifications. To perform a comprehensive testing of a program in practice, it is important to adopt both specification-based and implementation-based testing. In this paper we describe a relation-based test method that combines the specification-based and the implementation-based testing approaches. We establish a set of relations for test case generation, illustrate how the method is used with an example, and investigate the effectiveness and weakness of the method through an experiment on testing a software tool system.
