Visual programming versus textual programming in automatic testing and diagnosis

The present paper investigates the categories of functionality implemented by software in Automatic Test Systems and the programming paradigms that are commonly used for implementation. Building on the conclusions of this analysis, the paper proposes a combined development paradigm, where visual programming is used at diagnosis level, while both textual and visual languages are supported for implementing test and instrument control functionality. This approach offers important benefits in reducing development and maintenance costs for ATS software, while maximizing its potential for reuse. The proposed development paradigm is illustrated by an actual ATS architecture, implemented in software product
