            studentUnderTest.setAge(11);
            studentUnderTest.setName("test");
        }
    
        @Test
        public void testEquals() {
            // Run the test
            final boolean result = studentUnderTest.getName().equals("test");
            // Verify the results
            assertThat(result).isTrue();
        }
    
        @Override
        protected Student getT() {
