您如何使用 MUnit XML 验证出站属性？

Question

我在将负载发送到 JMS 队列之前在消息中设置了一些出站属性，并且我想在将消息发送到 JMS 队列之前测试这些属性是否已在消息中正确设置。

我考虑过在 JMS Outbound Endpoint 之前使用 MUnit Spy，但 Spy 只能验证会话属性、调用属性和有效负载。有没有其他方法可以使用 MUnit XML?

我创建了一个迷你 mule 项目来进一步说明这个问题。下面提供了代码。本质上，它只是一个调用子流的流，该子流在 mule 消息中设置出站属性，并且 MUnit 有一个间谍断言在调用子流后在 mule 消息中设置了出站属性。但是，MUnit Spy 似乎无法访问 mule 出站属性。我想知道此时是否有其他解决方法。我知道文档指定间谍此时只能验证会话和调用属性以及有效负载。欢迎任何建议。

不要为此使用 'Spy'，它有一些限制。查看文档：

https://docs.mulesoft.com/mule-user-guide/v/3.7/the-spy-message-processor#defining-spy-actions

您可以简单地在流程引用之后添加断言。

<munit:test name="outbound-props-flow-outbound-props-flowTest" description="Test">  
    <flow-ref name="outbound-props-flow" doc:name="Flow-ref to outbound-props-flow"/>
    <munit:assert-on-equals message="outbound-props-1 is not set properly" expectedValue="test1" actualValue="#[message.outboundProperties['outbound-prop-1']]" doc:name="Assert outbound-props-1 is set properly"/>
    <munit:assert-on-equals message="outbound-props-2 is not set properly" expectedValue="test2" actualValue="#[message.outboundProperties['outbound-prop-2']]" doc:name="Assert outbound-props-2 is set properly"/>
</munit:test>
