| Abstract: | A compiler-based specification and testing system for defining data types has been developed. The system, DAISTS (data abstraction implementation, specification, and testing system) includes formal algebraic specifications and statement and expression test coverage monitors. This paper describes our initial attempt to evaluate the effectiveness of the system in helping users produce software. In an exploratory study, subjects without prior experience with DAISTS were encouraged by the system to develop effective sets of test cases for their implementations. Furthermore, an analysis of the errors remaining in the implementations provided valuable hints about additional useful testing metrics. |
