I have created a custom VariableType called Object type which extends SerializableType. This type marshals a java bean to xml and then uses a wrapper to serialize the XML and store it in the activiti tables.
This all works fine. I have written a unit test for this but I cannot create a VariableInstanceEntity as SerializableType relies on a DB session.
Is there any way to test the SerializableType or mock the db session.
