Overview of this book

Angular makes building applications with the web easy and Spring Boot helps get an application up and running using just a few lines of code and minimal configuration. This book provides insights into building full-stack apps using Angular and Spring Boot effectively to reduce overall development time and increase efficiency. You'll start by setting up your CI/CD pipeline and then build your web application’s backend guided by best practices. You'll then see how Spring Boot allows you to build applications faster and more efficiently by letting the Spring Framework and Spring Boot extension do the heavy lifting. The book demonstrates how to use Spring Data JPA and add its dependencies along with Postgres dependencies in the project to save or persist a user's data in a database for future use. As you advance, you'll see how to write tests and test a service using Mockito. Finally, you'll create a CI workflow or pipeline for a Spring Boot and Angular application to enable operations to deliver quality applications faster. By the end of this Spring Boot and Angular book, you'll be able to build a full-stack web application and deploy it through continuous integration and continuous deployment.

Understanding JUnit and AssertJ

After every development of an application, testing will always be the next step, and this is one of the most important tasks before delivering or deploying our application into production for the world. The testing phase is critical for companies, as this ensures the quality and effectiveness of their products.

As this is one of the essential processes, there should be little room for errors in testing, and manual testing is not enough, as this is prone to human errors and has a more significant chance of missing the existing issues in an application. This is where unit testing comes to the rescue – unit testing is automated testing that allows the developer to write tests for a single class or entity.

It is a form of regression testing that runs all of the tests to validate whether the code still passes the test cases after several changes or updates have been applied to the application code. Unit tests help maintain the quality of our...
