equals/hashCode is useful in tests also when you want the check that the returned object is what you expect, instead of doing field by field comparison: Foo foo = bar.foo(); Assertions.assertThat(foo).equalTo(new Foo(1, 2, 3)); instead of: Foo foo = bar.foo(); Assertions.assertThat(foo.getFirst()).equalTo(1); Assertions.assertThat(foo.getSecond()).equalTo(2); Assertions.assertThat(foo.getThird()).equalTo(3);
