process.isEnded always returns false

[Thomas Winkler]

Hi,

we are currently building up a system using a workflow engine for massive data processing and recently started using Camunda BPM.  When unit testing some exmaple workflows I found out that the process instance I was testing always returned false when invoking process.isEnded() even the endpoint has been reached.

So my question is wether a process instance is set to isEnded == true just when an EndEvent is reached or is there something else required?

I did not yet fully dig into the source code, but this would be my next try...

If required I can post a code example as well if required.

Thanks in advance,

Thomas

Hi Thomas.

 

A test case (+ bpmn 2 xml) would indeed help to understand your case. Now I can only guess – let me try ;-)

 

If a process instance runs through till the end it is removed from the runtime database and only exists in the history database afterwards (I hope you don’t mind if I quote old camunda fox docs – which are not yet migrated: https://app.camunda.com/confluence/display/foxUserGuide/History#History-Overview). So you have to query the process instance from the history to check if it is ended (or check if a query on the runtime returns no result).

 

A typical testcase would do something like this: https://github.com/camunda/camunda-bpm-platform/blob/master/examples/invoice/src/test/java/org/camunda/bpm/example/invoice/InvoiceTestCase.java

 

And this checks for completion at the end via:

  public static void assertProcessEnded(ProcessEngine processEngine, String processInstanceId) {

    ProcessInstance processInstance = processEngine

      .getRuntimeService()

      .createProcessInstanceQuery()

      .processInstanceId(processInstanceId)

      .singleResult();

   

    if (processInstance!=null) {

      throw new AssertionFailedError("expected finished process instance '"+processInstanceId+"' but it was still in the db");

    }

  }

 

Hope that helps

Cheers

Bernd
