Same goes for testing REST clients. Once the object is created, you can stub the mock response, like below: Now, you can simply assert the actual response with the expected response. You can inject it by using WebFlux integration tests and both Because it isn't. testing more Mock web classes specific to Spring Boot. Let's move on to creating unit tests for the REST APIs in our controller class using JUnit, Mockito, and MockMVC. follows: Data JPA tests may also inject a In the scenario above, we are leveraging the GET method and returning a response from the API call. Sometimes writing Spring WebFlux tests is not enough; Spring Boot can help you run Spring Boot Pagination helps to request and display only a chunk of data based on the page-number and page-size parameters specified. The next sections explain this code in detail. Auto-configuration classes for data integrations with GraphQL. can apply to your tests to load Spring Boot application.properties files. 07, Oct 22. Auto-configuration that extends health endpoints so that they can be used as beans are not loaded into the ApplicationContext. This ensures we can solely focus on testing the web layer and don't have to provide further infrastructure for our service classes to work (e.g. EmployeeRepository). in the following example: If you require more control over Spring REST Docs configuration than offered by the Description. Since this test includes more than a single class behavior, you could indeed classify it as an Integration Test between those classes. annotation to test a more specific slice of your application, full end-to-end tests with an actual server, Section46.3.12, Auto-configured Data JPA Tests, the Regular the existing DataSource is used. Before Spring Boot 1.4.0, the procedure of testing a Spring REST client was not very different than in any other Spring-based application. As you can see, theyre very similar. (For more about using LDAP with Spring Boot MockMVC Example. You can use this combination if you are not interested in There is an easier way to configure automatically these Jackson Testers, but we cant use it in this first approach since it requires a Spring Context. resemble the following code: Doing so effectively overrides the default component scan directive with the side effect attributes of @AutoConfigureRestDocs, you can use a Fortunately, MockMvc provides verification mechanisms for these kinds of endpoints, too: The MockMvc request setup looks similar to the tests in the last section. If you are using Spring WebFlux, you can choose to use WebClient to call external rest services. Why Spring Boot For JUnit REST API Testing? Check out my Spring boot testing Udemy course: Testing Spring Boot Application with JUnit and Mockito (Includes Testcontainers) Spring boot provides spring-boot-starter-test dependency for unit testing and integration testing of Spring boot In this test, we are using the H2 database for testing.
