Thank you,

Hi @fernando123,

you can use the maven dependencies mentioned in the docs here: https://docs.camunda.org/manual/7.12/user-guide/testing/#camunda-assertions.

In your JUnit tests you can write:

assertThat(processInstance).isWaitingAt("SendNotificationTask").externalTask().hasTopicName("notification");
complete(externalTask());

If needed, you can pass variables in the compete() method as well:

compete(externalTask(), withVariables("resultVar1", "Value1", "resultVar2", true));

All helpers and assertions are listed here: https://github.com/camunda/camunda-bpm-assert/blob/master/docs/User_Guide_BPMN.md

Hope this helps, Ingo
