Title Body

Say I have a class with no equals() method, to which do not have the source. I want to assert equality on two instances of that class. I can do multiple asserts: assertEquals(obj1.getFieldA(), obj2.getFieldA()); assertEquals(obj1.getFieldB(), obj2.getFieldB()); assertEquals(obj1.getFieldC(), obj2.getFieldC()); ... I don't like this solution because I don't get the full equality picture if an early assert fails. I can manually compare on my own and track the result: String errorStr = ""; if(!obj1.getFieldA().equals(obj2.getFieldA())) { errorStr += "expected: " + obj1.getFieldA() + ", actual: " + obj2.getFieldA() + "\n"; } if(!obj1.getFieldB().equals(obj2.getFieldB())) { errorStr += "expected: " + obj1.getFieldB() + ", actual: " + obj2.getFieldB() + "\n"; } ... assertEquals("", errorStr); This gives me the full equality picture, but is clunky (and I haven't even accounted for possible null problems). A third option is to use Comparator, but compareTo() will not tell me which fields failed equality. Is there a better practice to get what I want from the object, without subclassing and overridding equals (ugh)?
