Hands-On Reactive Programming in Spring 5

By: Oleh Dokuka, Igor Lozynskyi

Overview of this book

These days, businesses need a new type of system that can remain responsive at all times. This is achievable with reactive programming; however, the development of these kinds of systems is a complex task, requiring a deep understanding of the domain. In order to develop highly responsive systems, the developers of the Spring Framework came up with Project Reactor. Hands-On Reactive Programming in Spring 5 begins with the fundamentals of Spring Reactive programming. You’ll explore the endless possibilities of building efficient reactive systems with the Spring 5 Framework along with other tools such as WebFlux and Spring Boot. Further on, you’ll study reactive programming techniques and apply them to databases and cross-server communication. You will advance your skills in scaling up Spring Cloud Streams and run independent, high-performant reactive microservices. By the end of the book, you will be able to put your skills to use and get on board with the reactive revolution in Spring 5.1!

Testing the Reactive Application

So far, we have covered almost everything about reactive programming using Spring 5.x. We have also looked at how to build a clean, asynchronous execution using Project Reactor 3 and how to use that knowledge for building web applications using WebFlux. Moreover, we learned how Reactive Spring Data complements the whole system, and how quickly we can upgrade our application to a cloud level one using Spring Cloud and Spring Cloud Streams.

In this chapter, we will finalize our knowledge base by learning how to test each component in our system. We will cover the testing techniques and utilities that help in the verification code, which is written using Reactor or any library that is compatible with the Reactive Streams specification. We will also look at features offered by the Spring Framework to test the reactive...
