### Question:
DateUtils { public static String getCNWeek(int week) { String str_week = ""; switch (week) { case 1 : str_week = "星期一"; break; case 2 : str_week = "星期二"; break; case 3 : str_week = "星期三"; break; case 4 : str_week = "星期四"; break; case 5 : str_week = "星期五"; break; case 6 : str_week = "星期六"; break; case 7 : str_week = "星期日"; break; } return str_week; }  static int getWeekByDate(Date date); static String getCNDefaultDate(); static String getCNWeek(int week); static String getFormatedDate(Date date); static String getFormatedDate(Date now, String format); static String getSimpleFormatDate(Date date); static String getSimpleFormatedDateNow(); static String getStandTime(); static Date parseStringToDate(String date); static Date parseStringToDate(String date, String format);  }### Answer:
@Test public void testGetCNWeek() { int week = DateUtils.getWeekByDate(new Date()); String cnWeek = DateUtils.getCNWeek(week); Assert.assertTrue("默认中文星期不应该为空字符串！week(" + week + ")", !"".equals(cnWeek)); }
