Testability and Testing of Microservices - Complex Challenge

Abstract: Microservices has become one of the most popular software engineering approach for modern web and IoT applications. Nevertheless, the testability and the testing processes require a comprehensive study that expands the testability model to a wider approach, focusing on the “not-testable” perspective. This paper presents the issues areas and proposes a conceptual framework for testability and testing of applications created with Microservices architecture - a multi-dimension testing approach for improving the process and the outcome. As the transfer from monolithic to Microservices architecture led to a major shift of complexity from the actual basic code into the implementation. This paper explores testing levels and dimensions suggesting a new holistic framework to address the existing challenges
