Junit Mock for value map properties of Long type
I am trying to write jnuit test classes for my class and attaching the screenshot below from debug view. Photoserialvalue is coming as null in my main class

Below is how i am trying to mock it.

Any leads on what is that I am missing? I am getting all other objects mocked and just this variable is coming as null. It is a Long type variable.
Any leads would be much appreciated.
