Mastering Spring Cloud

By: Piotr Mińkowski

Overview of this book

Developing, deploying, and operating cloud applications should be as easy as local applications. This should be the governing principle behind any cloud platform, library, or tool. Spring Cloud–an open-source library–makes it easy to develop JVM applications for the cloud. In this book, you will be introduced to Spring Cloud and will master its features from the application developer's point of view. This book begins by introducing you to microservices for Spring and the available feature set in Spring Cloud. You will learn to configure the Spring Cloud server and run the Eureka server to enable service registration and discovery. Then you will learn about techniques related to load balancing and circuit breaking and utilize all features of the Feign client. The book now delves into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures. Before running an application on Docker container s, you will master testing and securing techniques with Spring Cloud.

Testing Spring Boot applications

As you might have read in the previous section, there are some different strategies and approaches to the tests in your application. I have briefly mentioned all of them, so now we may proceed to the practical aspects. Spring Boot provides a set of utilities that help in the implementation ofautomated tests. In order to enable these features in the project, you have to include thespring-boot-starter-teststarterto the dependencies. It imports not only thespring-testandspring-boot-testartifacts, but also some other useful test libraries, such as JUnit, Mockito, and AssertJ:


Building the sample application

Before we start to work on automated tests, we need to prepare a sample business logic for testing purposes. We may use the same example system from the previous...
