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.

In this chapter, I have introduced some frameworks that can help you effectively test your REST-based applications written in Java. Each of these solutions has been assigned to a particular type of test. I focused on tests strictly related to microservices, such as contract and component tests. The main goal of this chapter was to compare the two most popular frameworks used for contract testing, namely Pact and Spring Cloud Contract. Despite appearances, there are some significant differences between them. I tried to show you the most important similarities and differences based on the same sample applications that we looked at in previous chapters.

Microservices are strictly related to automation. Remember that migration from monolith to microservices gives you an opportunity to refactor your code, and, moreover, to improve the quality and code coverage of your automated tests. Frameworkssuch as Mockito, Spring Test, Spring Cloud Contract, and Pact, when used together, give you...
