                                         T... unequals)

Tests Object.equals(Object) and Object.hashCode() methods partially testing consistency property: Fields that are not part of the Object.equals(Object) are not modified - no EqualityTester.Exerciser is used.

Type Parameters:

T - type of the object to test

Parameters:

obj - base object

equal1 - an object expected to be equal to the base

equal2 - an object expected to be equal to the base

unequals - a set of objects expected not to be equal to the base
