为我的基于maven的mule项目进行munit（xml）测试。
以下是仅使用记录器的样本批次
<batch:job name="sample-mavenBatch">
<batch:input>
<logger message="I am in input phase" level="INFO" doc:name="Logger"/>
</batch:input>
<batch:process-records>
<batch:step name="Batch_Step">
<logger message="I am in processing phase" level="INFO" doc:name="Logger"/>
</batch:step>
</batch:process-records>
<batch:on-complete>
<logger message="I am in complete phase" level="INFO" doc:name="Logger"/>
</batch:on-complete>
</batch:job>
The corresponding test for the flow
<munit:test name="new-test-suite-sample-mavenBatchTest" description="Test">
<munit:set payload="#['rasmita']" doc:name="Set Message"/>
<synchronize:run-and-wait doc:name="Synchronize">
<batch:execute name="sample-mavenBatch" doc:name="Run Batch sample-mavenBatch"/>
</synchronize:run-and-wait>
</munit:test>
这会让我遇到以下异常

其中相同的测试用例适用于非maven mule项目。
请帮帮我。提前谢谢。
答案 0 :(得分：0)
这是Munit输入集的问题。正如错误信息明确指出
Object "java.lang.String" not of correct type. It must be of type "{interface java.lang.Iterable,interface java.util.Iterator,interface org.mule.routing.MessageSequence,interface java.util.Collection}" (java.lang.IllegalArgumentException) (com.mulesoft.module.batch.exception.BatchException) (org.mule.api.DefaultMuleException).
批量输入应该是Iterable，但是您提供了字符串#['rasmita']。而不是尝试传递数组列表。您可以使用MEL或dataweave。
希望这有帮助。
答案 1 :(得分：0)
我以两种方式解决了我的问题
1) in Set payload as @anupambhusari said use arraylist, so using MEL #[{'rasmita','ananda'}]
2)With transform message which was throwing the below exception org.threeten.bp.zone.ZoneRulesProvider: Provider org.threeten.bp.zone.TzdbZoneRulesProvider
Added the below dependency.
