Examples of com.google.common.testutils.EqualsTester$NotAnInstance

com.google.common.testutils.EqualsTester
Class used to test whether equals() correctly handles an instance of an incompatible class. Since it is a private inner class, the invoker can never pass in an instance to the tester

    assertTrue(isComparable.apply(""));
    assertFalse(isComparable.apply(null));
  }


  public void testIsInstanceOf_equality() {
    new EqualsTester(Predicates.instanceOf(Integer.class))
        .addEqualObject(Predicates.instanceOf(Integer.class))
        .addNotEqualObject(Predicates.instanceOf(Number.class))
        .addNotEqualObject(Predicates.instanceOf(Float.class))
        .testEquals();
  }
