How to create modular microservice test projects

Let’s be very honest, cloud computing cannot be learned in one day. There are several architectural challenges to deploying your application, such as which framework to choose, reflection or reflectionless, native or non-naive. We also have the operational challenges such as backups, CI/CD, and much more.

This presentation explains how to make some of these design choices and the tradeoffs to consider when building applications to run in a virtual cloud environment.

Survival Guide for the Java Architect in the Cloud Era

The world is now full of distributed micro-services, generating different types of applications: the ones you are using to browse your social networks, to help professionals spend less time on repetitive tasks, and even to save lives.

We learned that testing the API layer with different approaches brings several benefits but also a complexity that can be measured in code duplication, high maintenance costs, and error-prone tests.
To solve this problem, in terms of how to test it, we can apply the same logic applied in microservices development: isolating them.
By creating a client and test projects for each microservice we can provide methods that other test projects can consume, easily enabling e2e tests creation.

During this presentation, I will show you how we can create it from scratch or decompose an existing test project and a real success case of a company that delivers hundreds of microservices to its customers.
