Using @WebMvcTest will auto-configure all web layer beans by looking for a @SpringBootConfiguration class (such as @SpringBootApplication).
If the configuration class is in a different package and can't be found by scanning, can I provide it directly to @WebMvcTest?
The following will point to the correct @SpringBootApplication class:
@RunWith(SpringJUnit4ClassRunner.class)
@WebMvcTest(controllers = {MyController.class})
@ContextConfiguration(classes={MySpringBootApplicationClass.class})
public class MyControllerTest {
//...
}
If you are using @WebMvcTest for your test , it means you are focusing mainly on testing the spring mvc layer and not going any deeper into the application.
So this annotation can be used only when a test focuses on Spring MVC components. By default, tests annotated with @WebMvcTest will also auto-configure Spring Security and MockMvc (include support for HtmlUnit WebClient and Selenium WebDriver). For more fine-grained control of MockMVC the @AutoConfigureMockMvc annotation can be used.Typically @WebMvcTest is used in combination with @MockBean or @Import to create any collaborators required by your @Controller beans.
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
@Configuration
@Import({ CustomerConfig.class, SchedulerConfig.class })
public class AppConfig {
}
You can then import this configuration class using @import in the @WebMvcTest annotated test class and the beans should be picked up by spring.
