SpringExtension for JUnit 5: Why Do We Need It?
SpringExtension integrates the Spring TestContext Framework into JUnit 5 Jupiter extension model, sets up the ApplicationContext, and manages dependencies.
Spring @Sql, @SqlGroup and @SqlMergeMode
Spring @Sql executes DDL and DML SQL scripts and statements during the integration testing. @SqlGroup groups multiple @Sql statements.
Testing REST Controllers with Spring Boot @RestClientTest
Learn to use @RestClientTest annotation provided by Spring boot test module that focuses only on beans that use RestTemplateBuilder or RestTemplate.
Spring Boot @DataJpaTest
Spring boot @DataJpaTest annotation focuses on JPA components and apply configuration only relevant to JPA tests. It helps in testing @Repository classes.
Spring Boot @MockBean Example
Spring boot @MockBean annotation used to add mocks to a Spring ApplicationContext. In this tutorial, we will learn the different ways to use this annotation.
Spring Boot @WebFluxTest and WebTestClient with JUnit 5
Learn to unit test Spring Boot webflux controller using @WebFluxTest and WebTestClient, which is used to test reactive endpoints with JUnit.
Integration Testing with @SpringBootTest and JUnit 5
The @SpringBootTest annotation in Spring Boot allows us to create integration tests by loading the entire application context. It acts as a bridge between the application configuration and the test framework so that tests can verify the behavior of your application in an environment similar to production.
Spring Boot @TestConfiguration Example
Learn to create and import test configurations in spring boot applications with the help of @TestConfiguration annotation.
Spring Boot 3 with JUnit 5
Learn to include JUnit 5 in a Spring boot application and write unit tests. Check out a demo of JUnit 5 tests for Spring Boot REST controller.
Spring Boot MockMvc Example with @WebMvcTest and MockitoBean
Test Spring Boot REST controllers with MockMvc and @WebMvcTest. Replace the service with a @MockitoBean mock and send GET, POST, PUT and DELETE requests with JSON. Then check status codes, validation errors and @RestControllerAdvice responses. Also covers MockMvcTester (AssertJ) and real andDo(print()) output on Spring Boot 4.1.1.
Unit Testing DAO Layer: A Practical Guide
