Spring Cloud Contract - Stub Runner for messaging by using AmqpInboundChannelAdapterSpec - spring-integration-dsl

Question

I tried to integrate Spring Cloud Contract Verifier Stub Runner’s messaging module with Spring AMQP. I created SimpleMessageListenerContainer with MessageListener and it works fine.
But I have another approach. I use a AMQP support for Spring Integration with Inbound Channel Adapter to receive a message from a queue.
Is it possible to use Spring Cloud Contract Verifier Stub Runner’s messaging module for AmqpInboundChannelAdapter?
CONTRACT
Contract.make {
description 'insert new message'
label 'test.queue.insert'
input {
triggeredBy('insertMessage()')
}
outputMessage {
sentTo 'test.exchange'
headers {
header('contentType': 'application/json')
header('__TypeId__': 'sk.bulalak.messaging.demospringcloudcontractmessaging.Person')
}
body('''{"firstName": "Janko", "lastName": "Hrasko"}''')
}
}
APPLICATION
#SpringBootApplication
#EnableIntegration
public class DemoSpringCloudContractMessagingApplication {
private Log logger = LogFactory.getLog(getClass());
public static void main(String[] args) {
SpringApplication.run(DemoSpringCloudContractMessagingApplication.class, args);
}
#Bean
public Queue testQueue() {
return QueueBuilder.durable("test.queue").build();
}
#Bean
public Exchange testExchange() {
return ExchangeBuilder
.topicExchange("test.exchange")
.durable(true)
.build();
}
#Bean
public Binding testBinding() {
return BindingBuilder
.bind(testQueue())
.to(testExchange())
.with("#")
.noargs();
}
#Bean
public MessageConverter messageConverter(ObjectMapper objectMapper) {
return new Jackson2JsonMessageConverter(objectMapper);
}
#Bean
public IntegrationFlow amqpInbound(ConnectionFactory connectionFactory, MessageConverter messageConverter) {
return IntegrationFlows.from(Amqp.inboundAdapter(connectionFactory, testQueue()).messageConverter(messageConverter))
.handle(p -> logger.info(p.getPayload()))
.get();
}
}
TEST
#RunWith(SpringRunner.class)
#SpringBootTest
#AutoConfigureStubRunner(ids = "org.example:test-service")
public class DemoSpringCloudContractMessagingApplicationTests {
#Autowired
private StubTrigger stubTrigger;
#Test
public void contextLoads() {
boolean result = stubTrigger.trigger("test.queue.insert");
assertTrue(result);
}
}

Answer 1

Disable the AMQP stub runner support stubrunner.amqp.enabled=false and just use the Spring INtegration one.
Custom route:
<beans:beans xmlns="http://www.springframework.org/schema/integration"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/integration
http://www.springframework.org/schema/integration/spring-integration.xsd">
<!-- REQUIRED FOR TESTING -->
<bridge input-channel="output"
output-channel="outputTest"/>
<channel id="outputTest">
<queue/>
</channel>
</beans:beans>
and run the test with that context
#ContextConfiguration(classes = Config, loader = SpringBootContextLoader)
#ImportResource("classpath*:integration-context.xml")
#AutoConfigureStubRunner
class IntegrationStubRunnerSpec extends Specification {
