    <p>I have a problem using java.util.Calendar and commons-lang DateUtil The problem is that my test works correctly on local machine and fails on CloudBees. Seems like there are problems with locales, but I'm not sure.</p> <p>Here is the code:</p> <pre><code>import org.testng.Assert; import org.testng.annotations.BeforeClass; import org.testng.annotations.Test; //bla-bla-bla public static final String TEST_DATE_AS_STRING = "13 10 2012 20:50:44"; public static final int MILLIS_IN_HOUR = 3600000; private static final String LEAP_WEEK_DATE_AS_STRING = "31 10 2012 20:50:44"; private final SimpleDateFormat sdf = new SimpleDateFormat("dd MM yyyy HH:mm:ss"); @Test public void getWeekDatePair() throws ParseException{ Date date = sdf.parse(TEST_DATE_AS_STRING); DatePair dp = Util.DateTime.getWeekDatePair(date); Assert.assertEquals(sdf.format(new Date(dp.getStart())), "08 10 2012 00:00:00"); //java.lang.AssertionError: expected [14 10 2012 00:00:00] but found [07 10 2012 00:00:00] Assert.assertEquals(sdf.format(new Date(dp.getEnd())), "14 10 2012 00:00:00"); } @Test public void getLeapWeekDatePair() throws ParseException { Date leapDate = sdf.parse(LEAP_WEEK_DATE_AS_STRING); DatePair dp = Util.DateTime.getWeekDatePair(leapDate); Assert.assertEquals(sdf.format(new Date(dp.getStart())), "29 10 2012 00:00:00"); //java.lang.AssertionError: expected [04 11 2012 00:00:00] but found [28 10 2012 00:00:00] Assert.assertEquals(sdf.format(new Date(dp.getEnd())), "04 11 2012 00:00:00"); } </code></pre> <p>Here is failed test output:</p> <pre><code> java.lang.AssertionError: expected [04 11 2012 00:00:00] but found [28 10 2012 00:00:00] at org.testng.Assert.fail(Assert.java:94) at org.testng.Assert.failNotEquals(Assert.java:494) at org.testng.Assert.assertEquals(Assert.java:123) at org.testng.Assert.assertEquals(Assert.java:176) at org.testng.Assert.assertEquals(Assert.java:186) at ru.rating.utils.UtilDateTimeTest.getLeapWeekDatePair(UtilDateTimeTest.java:77) expected [14 10 2012 00:00:00] but found [07 10 2012 00:00:00] Stacktrace java.lang.AssertionError: expected [14 10 2012 00:00:00] but found [07 10 2012 00:00:00] at org.testng.Assert.fail(Assert.java:94) at org.testng.Assert.failNotEquals(Assert.java:494) at org.testng.Assert.assertEquals(Assert.java:123) at org.testng.Assert.assertEquals(Assert.java:176) at org.testng.Assert.assertEquals(Assert.java:186) at ru.rating.utils.UtilDateTimeTest.getWeekDatePair(UtilDateTimeTest.java:69) </code></pre> <p>Here is implementation:</p> <pre><code> public static DatePair getWeekDatePair(){ return getWeekDatePair(new Date()); } /** * This is test method * */ static DatePair getWeekDatePair( Date date){ Date truncDay = truncate(date.getTime(), Calendar.DAY_OF_MONTH); Calendar calStart = getCalendarInstance(date, Calendar.DAY_OF_MONTH); calStart.setTime(truncDay); calStart.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); Calendar calEnd = Calendar.getInstance(); calEnd.setTime(calStart.getTime()); calEnd.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY); return new DatePair(calStart.getTime(), calEnd.getTime()); } public static Date truncate(long date, int calField) { Calendar cal = getCalendarInstance(new Date(date), calField); cal = DateUtils.truncate(cal, calField); return cal.getTime(); } static Calendar getCalendarInstance(Date date, int calendarField){ //Calendar cal = Calendar.getInstance(); Calendar cal = new GregorianCalendar(Locale.ENGLISH); cal.setTime(date); if(calendarField!=Calendar.HOUR){ cal.set(Calendar.HOUR_OF_DAY, 0); } cal.set(Calendar.MINUTE, 0); cal.set(Calendar.SECOND, 0); cal.set(Calendar.MILLISECOND, 0); return cal; } </code></pre>

    1. COI'm confused because the none of the "expected" values in the output match up with those given in the code. In JUnit `Assert.assertEquals()` takes the *expected* value as the first argument and the *actual* value as the second. I'm uncertain if this is the same in TestNG; however, your code seems to be inconsistent with the order of these values.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
