Test date in switch

good morning. Sure i can do that.

What i really mean is to keep the node configuration as is and create a test environement.
So i dont need to change the application (or the node configuration in this case) after i have tested the workflow.

So i am looking for the way its ment to be to test large or complicated workflows
