How to make junit tests with service-Task(Implementation: Expression)

Camunda 7 Topics Discussion & Questions

Hi,
i have a question concerning Junit-Test with service-tasks(Implementation: Expression).
While running my junit test, the process stays at the first service Task.

I think the problem is, that the expression refers to a java class which is not visibile for the Camunda-Test-Engine.
It looks like this:
Expression: ${institutsController.getInstitutsnameById(Institutsnummer)}

I hope there is something to mok this class but i only found examples for service tasks with “Implemtation: Delegate Expression”. I hope anybody has an Junit example with a service Task “Implementation: Expression” and a Java Class within the Expression.
