如何使用MUnit XML驗證出站屬性？

Question

我在將消息發送到JMS隊列之前設置了消息中的一些出站屬性，並且我想測試這些消息在將消息發送到JMS隊列之前是否已正確設置。

我想過在JMS出站端點之前使用MUnit Spy，但是間諜只能驗證會話屬性，調用屬性和有效負載。有沒有另外一種方法可以使用MUnit XML來實現這一點？

我創建了一個迷你騾子項目來進一步說明問題。代碼如下所示。本質上，它只是一個流程，它調用一個在mule消息中設置出站屬性的子流程，並且MUnit有一個間諜在調用子流程後聲明出站屬性設置在mule消息中。但是，MUnit Spy似乎無法訪問mule出站屬性。我想知道此時是否有其他解決方法。我知道文檔指定間諜只能驗證會話和調用屬性以及此時的有效負載。任何建議都是值得歡迎的。

不要使用 '間諜'爲此，它有一些限制。看看在文檔：

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

你可以簡單地增加流動裁判後斷言。

<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>
