A Framework for Automatic Testing of Industrial Controller Code

current trend in many industries is the introduction of more sophisticated optimization and control algorithms for enhancing production, regularity, and the operation of the plant. Some industries, like the automotive, have successfully used rapid prototyping tools like The Mathwork's Real-Time Workshop® in order to make development, testing, and implementation of new solutions more efficient. However, more traditional industries, like the process industry, have not yet fully adopted these new tools for various reasons. However, as the trend is towards more use of advanced optimization and control solutions also in these industries, the demand for testing will be more and more prominent. In this paper, we present a new framework for data-driven functionality testing of industrial controller code and applications. This new tool enables unit, integration, system, and regression testing for industrial controller code and is one of many steps towards bridging the gap between traditional desktop software development and industrial controller code development.
