Have you used the @SpringBootTest annotation in your tests to run the Spring context?

The @SpringBootTest annotation is used for integration testing in Spring Boot. It loads the full application context, allowing testing of components in conditions close to a real run.

Example usage:

@SpringBootTest
public class MyServiceIntegrationTest {

    @Autowired
    private MyService myService;

    @Test
    public void testServiceMethod() {
        // testing the service method with the loaded context
        assertNotNull(myService);
        // additional checks
    }
}

This approach is useful when you need to test the interaction of multiple components or configurations, rather than just individual classes with mocks.
