JavaScript SBST Heuristics To Enable Effective Fuzzing of NodeJS Web APIs

JavaScript is one of the most popular programming languages. However, its dynamic nature poses several challenges to automated testing techniques. In this paper, we propose an approach and open-source tool support enable white-box applications using Search-Based Software Testing (SBST) We provide collect search-based heuristics like common Branch Distance Testability Transformations . To empirically evaluate our results, integrated technique into EvoMaster test generation tool, carried out analyses on system RESTful GraphQL APIs. Experiments 8 Web APIs running NodeJS show that leads significantly better results than existing black-box grey-box tools, in terms code coverage fault detection.
