Unit test with external task

Hi, guys!

I want to know, how dependencies I need with maven repository and how i do unit test in camunda with external task in java. I want to enter inside of handle method.

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:


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

I download other bpmn in the internet and works, I think is the bpmn file, but I need create a process instance without start an instance with bpmn file, thereĀ“s a way to do this?

I solved this issue, I openned the bpmn and I Copied the field id and paste

runtimeService.startProcessInstanceByKey(ā€œfield id of bpmnā€);
