有流将调用 http-outbound 端点。如果 http 不可用,我想为该场景编写测试用例(捕获流程中的异常并按 POSTMAN 的预期工作)。我尝试使用throw an exception来模拟消息处理为 http:request 时要抛出的异常。但它没有奏效。有人可以帮助如何在 munit 中模拟异常吗?

以下是我尝试过的代码:

    <munit:test name="test-project-test-suite-munit-testFlowTest3" description="Test" >
    <mock:when messageProcessor="mule:set-payload" doc:name="Mock">
        <mock:with-attributes>
            <mock:with-attribute name="doc:name" whereValue="#['Set Payload']"/>
        </mock:with-attributes>
        <mock:then-return payload="#['payload3']"/>
    </mock:when>
    <mock:when messageProcessor="mule:flow" doc:name="Mock">
        <mock:with-attributes>
            <mock:with-attribute name="name" whereValue="#[matchContains('munit-testFlow2')]"/>
        </mock:with-attributes>
        <mock:then-return payload="#[]">
            <mock:invocation-properties>
                <mock:invocation-property key="variable2" value="#['response2']"/>
            </mock:invocation-properties>
        </mock:then-return>
    </mock:when>
    <mock:throw-an exception-ref="#[new org.mule.api.MessagingException()]" whenCalling="http:request" doc:name="Throw an Exception">
        <mock:with-attributes>
            <mock:with-attribute name="doc:name" whereValue="#['HTTP-RES']"/>
        </mock:with-attributes>
    </mock:throw-an>
    <flow-ref name="munit-testFlow" doc:name="munit-testFlow"/>
    <munit:assert-payload-equals message="oops failed" expectedValue="#['error-response']" doc:name="Assert Payload"/>
 </munit:test>

而不是new org.mule.api.MessagingException()像下面这样使用

new IllegalArgumentException('messaging exception') 或者

new java.lang.Exception("messaging exception")

org.mule.api.MessagingException()是一个受保护的函数,可能无法以可能的方式使用。其实它又归于org.mule.api.MuleException()哪个 protected

工作代码

<munit:test name="sample-test-suite-sampleFlowTest" description="Test">
    <mock:throw-an exception-ref="#[new java.lang.Exception('messaging exception')]" whenCalling="http:request" doc:name="Throw an Exception">
    </mock:throw-an>
    <flow-ref name="sampleFlow" doc:name="sampleFlow"/>
    <logger level="INFO" doc:name="Logger"/>
</munit:test>
