Testing Method Security

For example, we can test our example from EnableReactiveMethodSecurity by using the same setup and annotations that we used in Testing Method Security. The following minimal sample shows what we can do:

Java
Kotlin

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = HelloWebfluxMethodApplication.class)
public class HelloWorldMessageServiceTests {
	@Autowired
	HelloWorldMessageService messages;

	@Test
	public void messagesWhenNotAuthenticatedThenDenied() {
		StepVerifier.create(this.messages.findMessage())
			.expectError(AccessDeniedException.class)
			.verify();
	}

	@Test
	@WithMockUser
	public void messagesWhenUserThenDenied() {
		StepVerifier.create(this.messages.findMessage())
			.expectError(AccessDeniedException.class)
			.verify();
	}

	@Test
	@WithMockUser(roles = "ADMIN")
	public void messagesWhenAdminThenOk() {
		StepVerifier.create(this.messages.findMessage())
			.expectNext("Hello World!")
			.verifyComplete();
	}
}

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = [HelloWebfluxMethodApplication::class])
class HelloWorldMessageServiceTests {
    @Autowired
    lateinit var messages: HelloWorldMessageService

    @Test
    fun messagesWhenNotAuthenticatedThenDenied() {
        StepVerifier.create(messages.findMessage())
            .expectError(AccessDeniedException::class.java)
            .verify()
    }

    @Test
    @WithMockUser
    fun messagesWhenUserThenDenied() {
        StepVerifier.create(messages.findMessage())
            .expectError(AccessDeniedException::class.java)
            .verify()
    }

    @Test
    @WithMockUser(roles = ["ADMIN"])
    fun messagesWhenAdminThenOk() {
        StepVerifier.create(messages.findMessage())
            .expectNext("Hello World!")
            .verifyComplete()
    }
}
