How can we verify 2-3 expected variables from a single workflow in test case?
You can use something like nested condition.
But if you can show some screenshot to understand like where you are exactly trying to do this and for one variable how are you doing this will help suggest a better solution.
Say if you three variables named var1, var2, var3
You can validate in two ways
Either with a IF activity when u r using sequence of activities
With FLOW DECISION when u r using flowchart of activities
