Verify that all getter methods are called

I have the following test where I need to verify that all getters of the Person class are being called. So far I have used mockito's verify() to make sure that each getter is called. Is there a way to do that by reflection? It can be the case that a new getter is added to the Person class but the test will miss that.

public class GetterTest {
    class Person{

        private String firstname;
        private String lastname;

        public String getFirstname() {
            return firstname;
        }

        public String getLastname() {
            return lastname;
        }
    }

    @Test
    public void testAllGettersCalled() throws IntrospectionException{
        Person personMock = mock(Person.class);
        personMock.getFirstname();
        personMock.getLastname();

        for(PropertyDescriptor property : Introspector.getBeanInfo(Person.class).getPropertyDescriptors()) {
            verify(personMock, atLeast(1)).getFirstname();
            //verify for any getter method not just getFirstName()
        }
    }
}
