Learning Spring Boot 3.0 - Third Edition

By: Greg L. Turnquist

Overview of this book

Spring Boot 3 brings more than just the powerful ability to build secure web apps on top of a rock-solid database. It delivers new options for testing, deployment, Docker support, and native images for GraalVM, along with ways to squeeze out more efficient usage of existing resources. This third edition of the bestseller starts off by helping you build a simple app, and then shows you how to secure, test, bundle, and deploy it to production. Next, you’ll familiarize yourself with the ability to go “native” and release using GraalVM. As you advance, you’ll explore reactive programming and get a taste of scalable web controllers and data operations. The book goes into detail about GraalVM native images and deployment, teaching you how to secure your application using both routes and method-based rules and enabling you to apply the lessons you’ve learned to any problem. If you want to gain a thorough understanding of building robust applications using the core functionality of Spring Boot, then this is the book for you. By the end of this Spring Boot book, you’ll be able to build an entire suite of web applications using Spring Boot and deploy them to any platform you need.

In the previous chapter, we learned how to secure an application through various tactics, including path-based and method-based rules. We even learned how to delegate to an external system such as Google to offload risk for user management.

In this chapter, we’ll learn about testing in Spring Boot. Testing is a multi-faceted approach. It also isn’t something that you ever really finish. That’s because every time we add new features, we should add corresponding test cases to capture requirements and verify they are met. It’s always possible to uncover corner cases we didn’t think of. And as our application evolves, we have to update and upgrade our testing methods.

Testing is a philosophy that, when embraced, enables us to grow our confidence in the software we build. In turn, we can carry this confidence to our customers and clients, demonstrating quality.

The point of this chapter is to introduce a wide range of...
