> The ToStringBuilder and ReflectionToStringBuilder are great tools for
> everyday development.
> We use them to show all the properties in an object, which comes handy
> especially for testing.
> However, JUnit with its assertEquals() just outputs the toString() of the two
> compared objects. For complex objects, this becomes unreadable.
> So, it would be great to have a DifferenceBuilder with a
> ReflectionDifferenceBuilder implementation to be able to get only the
> differing properties of two objects. The question is whether the two objects
> would have to be of the same type or not.
