Hi,
i would like to write an unit test for my process model. I attached the relevant section.
As you can see there are a few service tasks executed in parallel. All service tasks are external and have the same topic. Unfortunatelly, when I am executing the following line in test an exception occurs.
Test statement:
complete(externalTask(ServiceTasks.ACTIVITY_0EZE1FT), variableSnapshot);
Exception:
java.lang.IllegalStateException: Multiple external tasks found for externalTask = ‘ExternalTaskEntity [id=42, revision=1, topicName=externalTopic, workerId=null, lockExpirationTime=null, priority=0, errorMessage=null, errorDetailsByteArray=null, errorDetailsByteArrayId=null, executionId=40]’, variables = ‘{x=5}’

Taking a look into BPMNAwareTests.class you can see that the external tasks is locked by topic name. After that a check ensures that the locked external task has the same ID as the given one from my test statement. Because I am using multiple external tasks with the same topic the check fails and the exception occurs.
What am I doing wrong? Or is it a bug? I’m using org.camunda.bpm.assert in version 8.0.0.
Thank you for helping me.
