### Question:
MinMaxValueHelper { static boolean isValidValue(final HTMLInputElement input, final int inputValue) { final int max = toInteger(input.max, MAX_VALUE); final int min = toInteger(input.min, MIN_VALUE); return inputValue >= min && inputValue <= max; }  static void setupMinMaxHandlers(final HTMLInputElement input); static Integer toInteger(final String value,
                                    final Integer defaultValue);  }### Answer:
@Test public void testIsValidValueWhenWithoutMaxValue() { input.min = "0"; assertTrue(isValidValue(input, 0)); }
@Test public void testIsValidValueWhenWithoutMinValue() { input.max = "0"; assertTrue(isValidValue(input, 0)); }
