Overview of this book

Spring Boot provides a variety of features that address today's business needs along with today's scalable requirements. In this book, you will learn how to leverage powerful databases and Spring Boot's state-of-the-art WebFlux framework. This practical guide will help you get up and running with all the latest features of Spring Boot, especially the new Reactor-based toolkit. The book starts off by helping you build a simple app, then shows you how to bundle and deploy it to the cloud. From here, we take you through reactive programming, showing you how to interact with controllers and templates and handle data access. Once you're done, you can start writing unit tests, slice tests, embedded container tests, and even autoconfiguration tests. We go into detail about developer tools, AMQP messaging, WebSockets, security, and deployment. You will learn how to secure your application using both routes and method-based rules. By the end of the book, you'll have built a social media platform from which to apply the lessons you have learned to any problem. If you want a good understanding of building scalable applications using the core functionality of Spring Boot, this is the book for you.

Testing with Spring Boot

Most innovative contribution to the java ecosystem: spring Boot #jaxlondon

If we go back more than 10 years, we would find testing a process mostly conducted by legions of test engineers. But with the rise of JUnit, the adoption of continuous integration (CI) servers, a plethora of test assertion libraries, and integrated test coverage services, we can see widespread adoption of automated testing.

In this chapter, we will see how critical Spring Boot views automated testing by providing multiple levels of support. We shall do the following:

  • Write some basic unit tests
  • Introduce slice testing
  • Embark upon WebFlux testing
  • Leverage complete embedded container testing
  • Draft some autoconfiguration tests
