Presentation: Test automation vs distributed architecture
session level: advanced

While distributed system architecture is becoming a new standard in case of web application engineering, functional test automation is still struggling to catch up. Knowing the cost of frontend automation and having the majority of domain logic exposed by REST APIs, there is a strong need for robust and reliable end-to-end automated testing based on the backend side.
There’re many challenges in distributed systems for test automation: asynchronous calls, messaging protocol, domain modeling, just to name a few.
In this talk we will go step-by-step through designing and implementing end-to-end testing framework for microservices. We’ll dive into isolating environments, test strategy, code and automation. All of this based on lessons learnt from building automated a test solution for the real-world, complex distributed architecture.
