A Comprehensive Review of Testing Blockchain Oriented Software

This work presents a short review on the most relevant studies in the context of testing Blockchain-Oriented Software (BoS), especially at the smart contract level. Focusing on dynamic testing, we first provide a classification of 20 studies according to the accessibility of smart contract code. Second, we give an overview of each identified work while highlighting its advantages and limitations. Third, we discuss challenges and opportunities in this research area. After carrying out this review, it was noticed that there is much work to be done, especially in the context of model-based testing of smart contracts which can be a good research line for detecting defects and enhancing the quality of such applications.
