Overview of this book

Spring is a powerful and widely adopted framework for building scalable and reliable web applications in Java, complemented by Spring Boot, a popular extension to the framework that simplifies the setup and configuration of Spring-based applications. This book is an in-depth guide to harnessing Spring 6 and Spring Boot 3 for web development, offering practical knowledge of building modern robust web APIs and services. The book covers a wide range of topics that are essential for API development, including RESTful web service fundamentals, Spring concepts, and API specifications. It also explores asynchronous API design, security, designing user interfaces, testing APIs, and the deployment of web services. In addition to its comprehensive coverage, this book offers a highly contextual real-world sample app that you can use as a reference for building different types of APIs for real-world applications. This sample app will lead you through the entire API development cycle, encompassing design and specification, implementation, testing, and deployment. By the end of this book, you’ll have learned how to design, develop, test, and deploy scalable and maintainable modern APIs using Spring 6 and Spring Boot 3, along with best practices for bolstering the security and reliability of your applications and improving your application's overall functionality.

Create a new file called ProductDatafetcherTest.java inside the datafetchers package in the test directory and add the following code:

@SpringBootTest(classes = { DgsAutoConfiguration.class,     ProductDatafetcher.class,BigDecimalScalar.class })
public class ProductDatafetcherTest {
  private final InMemRepository repo = new InMemRepository();
  private final int TEN = 10;
  @Autowired
  private DgsQueryExecutor dgsQueryExecutor;
  @MockBean
  private ProductService productService;
  @MockBean
  private TagService tagService;
