What You See Is What You Test: A Methodology for Testing Form-Based Visual Programs

Form-based visual programming languages, which include commercial spreadsheets and various research systems, have had a substantial impact on end-user computing. Research shows, however, that form-based visual programs often contain faults. We would like to provide at least some of the bene ts of formal testing methodologies to the creators of these programs. This paper presents a testing methodology for form-based visual programs. To accommodate the evaluation model used with these programs, and the interactive processby which they are created, our methodology is validationdriven and incremental. To accommodate the users of these languages, we provide an interface to the methodology that does not require an understanding of testing theory. We discuss our implementation of this methodology and empirical results achieved in its use. KEYWORDS software testing, visual programming, spreadsheets
