Towards an approach for developing and testing Node-RED IoT systems
Diego Clerissi, Maurizio Leotta, Gianna Reggio, Filippo Ricca · 2018
Node-RED is a visual tool based on the flow-based programming paradigm and built on NodeJS, which is used for developing IoT systems. In Node-RED, the developer can follow her own personal flavour for wiring devices and online services together, and the same system can be developed in many different ways. Each day, the Node-RED community submits to users novel solutions, and even if there exist frameworks for testing Node-RED flows, they are not supported by a systematic testing technique. Hence, the freedom granted by Node-RED may hinder the understandability of the produced artefacts and the detection of faults.
