Asserting multiple attributes of an Object

Question

In order to assert multiple attributes of a call, I am planning to use auto-value.

But the documentation says:

  // You probably don't need to write assertions like these; just illustrating.
  assertTrue(Animal.create("dog", 4).equals(dog));
  assertFalse(Animal.create("cat", 4).equals(dog));
  assertFalse(Animal.create("dog", 2).equals(dog));

What are the better ways of asserting multiple attributs of dog?
