### Question:
ValidationUtils { public static void isBetween(Number value, String property, String messagePrefix, Number min, Number max, Errors error) { if (value == null || value.doubleValue() <= min.doubleValue() || value.doubleValue() > max.doubleValue()) { error.rejectValue(property, messagePrefix + " should be between " + min + " and " + max); } }  static void isNotEmpty(String value, String property, String messagePrefix, int length, Errors error); static void isEmpty(String value, String property, String messagePrefix, Errors error); static void isNotLongerThan(String value, String property, String messagePrefix, int length, Errors error); static void isNotEmpty(Collection collection, String property, String errorMessage, Errors error); static void isNotNull(Object value, String property, String messagePrefix, Errors error); static void isNull(Object value, String property, String messagePrefix, Errors error); static void contains(String sequence, String searchSequence, String property, String messagePrefix, Errors error); static void isGreaterThan(Number value, String property, String messagePrefix, Number min, Errors error); static void isGreaterOrEqualTo(Number value, String property, String messagePrefix, Number min, Errors error); static void isBetween(Number value, String property, String messagePrefix, Number min, Number max, Errors error); static void isBetweenInclusive(Number value, String property, String messagePrefix, Number min, Number max, Errors error); static void isNullOrGreaterOrEqualTo(Number value, String property, String messagePrefix, Number min, Errors error); static void isNullOrGreaterThan(Number value, String property, String messagePrefix, Number min, Errors error); static void isDefined(P entity, R repository, String property, String messagePrefix, Errors error); static void isAfter(Date value, String property, String messagePrefix, Date otherDate, Errors error); static boolean isAnId(@Null final String string); static void entityExists(Long id, CrudRepository repository, String property, String messagePrefix, Errors
            error);  }### Answer:
@Test public void shouldIsBetweenAcceptValidValue() throws Exception { ValidationUtils.isBetween(1, property, messagePrefix, 0, 2, error); verify(error, times(0)).rejectValue(anyString(), anyString()); }
