@MockBean (Mocking)
The @MockBean is used to mock a bean of the specific type, making it convenient to test components that depend on bean.
@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {
@Autowired
private MyService myService;
@MockBean
private ExternalService externalService;
@Test
public void testServiceMethod() {
// Define behavior for the mocked external service
when(externalService.getData()).thenReturn("Mocked Data");
// Now test the method from MyService that uses externalService
String result = myService.processData();
assertEquals("Processed: Mocked Data", result);
}
}
Testing in Spring Boot
In this article, we will be discussing Testing in Spring Boot. There are so many different testing approaches in Spring Boot used for deploying the application server. Testing in Spring Boot is an important feature of software development which ensures that your application behaves as per the requirement and meets all the testing criteria. Spring Boot provides a robust testing framework that supports Unit Testing, Integration Testing, and End-to-End Testing.
1. Unit Tests:
- The Focus is on testing individual components or units of the code in isolation.
- Use tools like JUnit and Mockito for the writing unit tests.
2. Integration Tests:
- Test the interactions between the multiple components or modules.
- Ensures that different parts of the application work together perfectly.
- Typically involves testing repositories, services, and controllers.
3. End-to-End (E2E) Tests:
- Test the entire application from the end to end simulating real user scenarios.
- Involve testing application’s behavior through its external interfaces.
- Use tools like Selenium for the web applications.
