Dynamic testing for any camunda bpmn process

I am working on a Camunda java code and i am looking for a testing methodology that i can use to test any of my bpmn processes.

i have made some google search and i found on Camunda documentation some ideas about unit testing but it is do test for a specific bpmn model . i need one to test any bpmn model (just by passing name of bpmn file and id of process etc) the strategy should take into account the integration with DB to get candidate (user&group) for any expected path.i know maybe i can't do that but i have a large model and it will be time waste to test all of it in traditional ways.
