Beyond the unit: a holistic approach for testing serverless architectures

Abstract

One of the peculiar aspects of microservices architecture is the possibility of designing a system as a set of independent but collaborative components. At the root of this collaboration there are well-defined contracts among all the microservices: breaking even a single contract might compromise the health of the entire system.
With AWS Lambda, we have the ability to simply create an ever-increasing number of microservices and, therefore, it becomes crucial to find a way to catch errors in advance whenever one of these contracts has been broken.
