        @Mock
        private Adder adder;
    
        @Test
        public void test() {
            ValidCalculator calculator = new ValidCalculator(adder);
            when(adder.add(1, 2)).thenReturn(3);
            int result = calculator.add(1, 2);
    
            verify(adder, times(1)).add(1, 2);
            softly.assertThat(result).isEqualTo(3);
            verifyNoMoreInteractions(adder);
        }
