Mule 如何使用MUnit XML验证出站属性？

在将有效负载发送到JMS队列之前，我在消息中设置了一些出站属性，我想在将消息发送到JMS队列之前测试这些属性是否在消息中正确设置

我曾考虑在JMS出站端点之前使用MUnit Spy，但Spy只能验证会话属性、调用属性和负载。有没有其他方法可以使用MUnit XML实现这一点

我创建了一个迷你mule项目来进一步说明这个问题。代码如下所示。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，而MUnit有一个间谍，它断言出站属性是在调用子流后在mule消息中设置的。然而，MUnit间谍似乎无法访问mule出站属性。我想知道在这个时候是否还有其他的解决办法。我知道文档指定spy此时只能验证会话和调用属性以及负载。欢迎提出任何建议

不要用“间谍”这个词，它有一些局限性。请参阅文档：

您可以简单地在flow ref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>

Hi Davo-鉴于间谍的局限性，我认为这是正确的方法！谢谢我认为这应该是mulesoft在其下一个munit版本中修复的东西。
