我试图为我的侦听器弹簧启动应用程序编写集成测试，在测试中将启动应用程序，然后创建消息，将其放入输出通道，等待消息被挑选和处理
这是我测试的内容：
if let vc = UIApplication.shared.keyWindow?.rootViewController as? YourViewController {
// do what u would like to
}
并且在package com.example;
import com.netflix.discovery.converters.Auto;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Source;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import static org.assertj.core.api.Assertions.assertThat;
import static org.springframework.integration.support.management.graph.LinkNode.Type.output;
@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("scratch")
public class DemoApplicationTests {
@Component
@EnableBinding(Source.class)
static class TestMessageSource {
@Autowired
private Source source;
public void sendMessage(String message) {
new Thread(() -> {
Message<Greeting> msg = MessageBuilder.withPayload(new Greeting(message)).build();
source.output().send(msg);
}).start();
}
}
static class CounterFakeService implements CounterService {
public int count = 0;
public Greeting greeting;
@Override
public void recordCount(Greeting greeting) {
count++;
this.greeting = greeting;
}
}
private CounterFakeService fakeCounterService;
@Bean
CounterService counterService() {
return fakeCounterService;
}
@Autowired
TestMessageSource messageSource;
@Before
public void before() {
fakeCounterService = new CounterFakeService();
// this.mvc = MockMvcBuilders.webAppContextSetup(this.context).build();
}
@Test
public void doesProcessMessages() throws InterruptedException {
assertThat(fakeCounterService.count).isEqualTo(0);
messageSource.sendMessage("test");
Thread.sleep(5000);
assertThat(fakeCounterService.count).isEqualTo(1);
assertThat(fakeCounterService.greeting.getMessage()).isEqualTo("test");
}
}
中我有输出通道绑定到输入交换
application-scratch.properties然而，目前，测试失败，因为没有收到任何消息。我应该寻找什么？
编辑 - 完整性的侦听器代码
PS：我已经确认这实际上适用于向spring.rabbitmq.host=rabbitmq.local.pcfdev.io
spring.rabbitmq.port=5672
spring.rabbitmq.password=i9jbk2o3ingqtkrekgm988bvui
spring.rabbitmq.username=8cf073b0-a2ff-450a-bee5-3954cb6c191f
spring.rabbitmq.virtual-host=5fc33451-4ec0-440e-90a1-6e7ed0c025f9
spring.cloud.stream.bindings.output.destination=input
交换机发送消息的其他应用程序。只是无法让测试工作：（
input答案 0 :(得分：0)
我没有看到带有入站通道的CounterService的任何@StreamListener配置。您还需要将入站通道的绑定配置指向同一目标input。
答案 1 :(得分：0)
Facepalm时间！ :) 所以我让实际的监听器在后台运行，并且正在拾取测试从未通过的所有消息
