Spring Boot REST API Complete Project - Master Unit Testing Java Spring Boot REST API Application in One Shot | Full Course

Let's become expert of unit testing java spring boot rest api application using Junit , AssertJ , Mockito , H2Database , Springframework test package libraries / frameworks. This is a full one shot course on software unit testing java spring boot applications. In this tutorial, Cloud Vendor API is further evolved and junit test cases are written for all 3 layers i.e. controller layer , service layer and repository layer. All layers are unit tested using junit, assertj, mockito, h2database and springframework test package . Code coverage method is also demonstrated in this session. Software testing expected from java developers is explained here. Unit Testing is mandatory task to perform in java projects from every Java developer. Unit testing java projects helps to enhance java code quality and prevents java spring boot application from bugs. This tutorial will be helpful for backend developers and also for full stack developers. Some notes - JUNIT - Unit testing framework for Java and its frameworks. JUnit 5 is the next generation of JUnit. The goal is to create an up-to-date foundation for developer-side testing on the JVM. This includes focusing on Java 8 and above, as well as enabling many different styles of testing. AssertJ - AssertJ is a Java library that provides a rich set of assertions and truly helpful error messages. It improves test code readability, and is designed to be super easy to use within your favorite IDE. Mockito - Mockito is a mocking framework for Java. It lets you write beautiful tests with a clean & simple API. The tests are very readable and they produce clean verification errors. Mockito 3.x requires Java 8 or above. H2 Database - H2 Database is Java SQL Database Very fast and open source Used as In-Memory Database Spring Boot can auto-configure embedded H2 databases.  Key Annotations - @SpringBootApplication @Test @DataJpaTest @WebMvcTest @Mock @MockBean @Autowired @BeforeEach @AfterEach and more...
