Hands-On Cloud Development with WildFly

By: Tomasz Adamski

Overview of this book

The book starts by introducing you to WildFly Swarm—a tool that allows you to create runnable microservices from Java EE components. You’ll learn the basics of Swarm operation—creating microservices containing only the parts of enterprise runtime needed in a specific case. Later, you’ll learn how to configure and test those services. In order to deploy our services in the cloud, we’ll use OpenShift. You’ll get to know basic information on its architecture, features, and relationship to Docker and Kubernetes. Later, you’ll learn how to deploy and configure your services to run in the OpenShift cloud. In the last part of the book, you’ll see how to make your application production-ready. You’ll find out how to configure continuous integration for your services using Jenkins, make your application resistant to network failures using Hystrix, and how to secure them using Keycloak. By the end of the book, you’ll have a functional example application and will have practical knowledge of Java EE cloud development that can be used as a reference in your other projects.

Testing Your Services with Arquillian

In this chapter, you will learn how to test your microservices. For this purpose, we will use Arquillian, a test framework designed to test software components using their dedicated runtime, instead of creating mock-based unit tests. This is the framework developer to work seamlessly WildFly Swarm and, effectively, a framework of choice for it.

We will introduce Arquillian and present the purpose of the project and its main features. Later, you will learn how to develop, write, and configure tests for your services based on practical examples.
