Spring Cloud Stream在消息的有效负载中测试硬编码的“Hello World”

Question

I'm trying out Spring Cloud Stream, and when i tried to run one of the simpliest test (original test available here: https://github.com/spring-cloud/spring-cloud-stream/blob/master/spring-cloud-stream-test-support/src/test/java/org/springframework/cloud/stream/test/disable/AutoconfigurationDisabledTest.java )

Using: Java 1.8 SpringBoot 2.1.5.RELEASE spring-cloud.version: Greenwich.RELEASE

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
@DirtiesContext
public class ExampleTest {

    @Autowired
    public MessageCollector messageCollector;

    @Autowired
    public Processor processor;

    @SuppressWarnings("unchecked")
    @Test
    public void testAutoconfigurationDisabled() {
        this.processor.input().send(MessageBuilder.withPayload("empty").build());

        Message<String> response = (Message<String>) this.messageCollector.forChannel(this.processor.output()).poll();

        Assertions.assertThat(response).isNotNull();
        Assertions.assertThat(response.getPayload()).isEqualTo("Hello World");
    }
}

Test passed, but it should not. Message is sent with "empty", and that is what i would expect to receive, but received payload always is "Hello World"

Please make sure you have compiled you test class after you change from "Hello world" to "". I ran into the occasion of test class not compiled and always get the previous result when I use maven with Intellij, and run test from maven view.
