What is the procedure to test an age based Life event like Child Dependent age change?

Summary

According to client company's requirement. Once the child dependent reaches 25 years,they can no longer have them as dependent and a life event be triggered so that the employees can modify their plans. 

Is there a way to test this for an employee by changing the effective date and checking if the life event gets triggered and the child is no longer listed under dependents.

FYI,the dependents are filtered by adding a eligibility profile in the Designate dependents.So I just wanted to make sure a life event gets triggered
