OrderService { public void validateOrderDate( @XPath(value = "/order:order/order:date", namespaces = @NamespacePrefix(prefix = "order", uri = "http: final Calendar calendar = new GregorianCalendar(); try { calendar.setTime(DATE_FORMAT.parse(date)); if (calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY) { LOGGER.warn("Order validation failure: order date " + date + " should not be a Sunday"); throw new OrderValidationException("Order date should not be a Sunday: " + date); } } catch (ParseException e) { throw new OrderValidationException("Invalid order date: " + date); } }  void validateOrderDate(
        @XPath(value = "/order:order/order:date",
            namespaces = @NamespacePrefix(prefix = "order", uri = "http://org.jboss.fuse.quickstarts/examples/order/v7")) String date); void randomlyThrowRuntimeException(@Header(Exchange.FILE_NAME) String name);  }### Answer:
@Test public void testValidateValidOrderDate() { try { service.validateOrderDate("2017-03-01"); service.validateOrderDate("2017-03-02"); service.validateOrderDate("2017-03-03"); service.validateOrderDate("2017-03-06"); } catch (OrderValidationException e) { fail("No OrderValidationException expected - we can accept orders on any of those dates"); } }
@Test(expected = OrderValidationException.class) public void testValidateInvalidOrderDate() throws OrderValidationException { service.validateOrderDate("2017-03-05"); }
