End-User Testing for the Lyee Methodology using the Screen Transition Paradigm and WYSIWYT

摘要

End-user specification of Lyee programs is one goal envisioned by the Lyee methodology. But with any software development effort comes the possibility of faults. Thus, providing end users a means to enter their own specifications is not enough; they must also be provided with the means to find faults in their specifications, in a manner that is appropriate not only for the end user's programming environment but also for his or her background. In this paper, we present an approach to solve this problem that marries two proven technologies for end users. One methodology for enabling end users to program is the screen transition paradigm. One useful visual testing methodology is ‘What you see is what you test (WYSIWYT)’. In this paper, we show that WYSIWYT test adequacy criteria can be used with the screen transition paradigm, and present a systematic translation from this paradigm to the formal model underlying WYSIWYT.
