Akka Persistence Durable State

Hi Folks

I am using Durable State for my project. Earlier I was using EventSourcedBehavior. Now I am using DurableStateBehavior. My code is working fine, but all my existing JUnits are failing.
I was using PersistenceTestKit. Is there any other test kit to be used for DurableState. I could not find any help regarding this topic.
