Is there a significant(or even any) difference between 'same' and 'eq' in EasyMock?

same
checks if both objects are actually the same instance (reference equality). eq
calls equals
and therefore checks if both have the same value (value equality).
Keep in mind that the default equals
implementation uses ==
internally, and therefore eq
will do the same as same
if you're using classes that do not have a proper equals
override.
But still, it's better to state your intent by using same
for reference equality and eq
for value equality. It might also help you finding bugs (i.e. finding that you forgot to override equals
).
