I wouldn't try to mock the RabbitMQ server itself; instead, mock your publication methods, channel factories, and so on in order to emulate error conditions (and the happy path, of course). What happens when your <code>FoozleEvent.publish</code> method throws an <code>IOError</code>, for example?

blocks|key|38987|text|我们在框架本身的测试中广泛使用mocking；探索tests以获取想法。这在RabbitTemplate方面还不错，但对侦听器容器的模拟更复杂一些。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|38988|然而，在某些情况下，需要一个真正的集成测试，在这种情况下，如果没有本地的rabbitmq代理，我们使用JUnit+@Rule来忽略测试。|38989|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/spring-projects/spring-amqp/tree/master/spring-rabbit/src/test/java/org/springframework/amqp/rabbit^0|12|E|P|5|0|0|1L|5|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]]|E|$]]|$1|F|3|G|5|6|7|V|8|@$9|W|A|X|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

We use mocking extensively for tests in the framework itself; explore the <a href="https://github.com/spring-projects/spring-amqp/tree/master/spring-rabbit/src/test/java/org/springframework/amqp/rabbit" rel="nofollow">tests</a> for ideas. It's not too bad on the <code>RabbitTemplate</code> side, but mocking for the listener container is more involved.

In some case, though, a real integration test is needed and in that case we use a JUnit <code>@Rule</code> to ignore the tests if there's not a local rabbitmq broker.

To mock RabbitMQ in the Java world, there is a library that I am building : <a href="https://github.com/fridujo/rabbitmq-mock" rel="nofollow noreferrer">rabbitmq-mock</a>.

The purpose is exactly the use case you describe. You can simply replace the amqp-client <code>ConnectionFactory</code> and you will have most of RabbitMQ features out of the box, without using IO (no port binding is needed) and without startup time.

Simply add the dependendy in your pom.xml:

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;com.github.fridujo&lt;/groupId&gt;
 &lt;artifactId&gt;rabbitmq-mock&lt;/artifactId&gt;
 &lt;version&gt;1.0.14&lt;/version&gt;
 &lt;scope&gt;test&lt;/scope&gt;
&lt;/dependency&gt;
</code></pre>

Then you can use it through a replacement of the ConnectionFactory you provided through Spring configuration or that Spring-Boot have provided for you:

<pre><code>@Configuration
@Import(AppConfiguration.class)
class TestConfiguration {
 @Bean
 ConnectionFactory connectionFactory() {
 return new CachingConnectionFactory(new MockConnectionFactory());
 }
}
</code></pre>

Hope this will help !

I am building an application using RabbitMQ with Spring: so far so good. 
To define Unit Tests I am using JUnit targeting an external server. 
What I wanted to find out is if there is a way to mock the RabbitMQ server to perform tests, and if there is more than a way, which is the best one. 

I found some posts around but they were made in 2012 or even before... maybe there's something newer, easier and more effective ! 

Thanks in advance

我正在使用RabbitMQ和Spring构建一个应用程序:到目前为止还不错。为了定义单元测试，我使用了针对外部服务器的JUnit。我想知道的是，是否有一种方法可以模拟RabbitMQ服务器来执行测试，如果有更多的方法，哪种方法是最好的。我在周围找到了一些帖子，但它们是在2012年甚至更早的时候写的。也许有更新、更简单、...
