  • the following is Test Generation MessageTest.java :
@SuppressWarnings("rawtypes")
public class MessageTest extends BaseCase {
	@Inject ContractVerifierMessaging contractVerifierMessaging;
	@Inject ContractVerifierObjectMapper contractVerifierObjectMapper;

	@Test
	public void validate_triggermessage() throws Exception {
		// given:
			ContractVerifierMessage inputMessage = contractVerifierMessaging.create(
					"{\"bookName\":\"foo\"}"
						, headers()
							.header("sample", "header")
			);

		// when:
			contractVerifierMessaging.send(inputMessage, "kafka-topic",
					contract(this, "triggermessage.yml"));

		// then:
			ContractVerifierMessage response = contractVerifierMessaging.receive("kafka-topic",
					contract(this, "triggermessage.yml"));
			assertThat(response).isNotNull();

		// and:
			assertThat(response.getHeader("BOOK-NAME")).isNotNull();
			assertThat(response.getHeader("BOOK-NAME").toString()).isEqualTo("foo");

		// and:
			DocumentContext parsedJson = JsonPath.parse(contractVerifierObjectMapper.writeValueAsString(response.getPayload()));
			assertThatJson(parsedJson).field("['bookName']").isEqualTo("foo");
	}

}

And contractVerifierMessaging.send Method hasn't parameter contract.

I guess the version is wrong, but I did not find a solution.

@marcingrzejszczak
the following is maven plugin :

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-contract-maven-plugin</artifactId>
                <version>${spring-cloud-contract.version}</version>
                <extensions>true</extensions>
                <configuration>
                    <baseClassForTests>
                        com.xzg.test.scc.BaseCase
                    </baseClassForTests>
                </configuration>
                <dependencies>

                </dependencies>
            </plugin>
        </plugins>

BaseCase.java

@SpringBootTest(classes = SpringcloudContractProviderRestApplication.class,webEnvironment = SpringBootTest.WebEnvironment.NONE)
// remove::start[]

    @Autowired KafkaController controller;

    public void trigger() {
        this.controller.sendFoo("example");
    }

    public void triggerMessage() {
        this.controller.sendFooAsMessage("example");
    }
        @BeforeEach

What is the <version>${spring-cloud-contract.version}</version> value?

@marcingrzejszczak

Ah I see it's 3.0.2. You're using incompatible release trains. You're using Hoxton against contract 3.x. You should use either Hoxton and maven plugin 2.x or 2020.x and contract 3.x
