-------------------------------------------------------
Key: LANG-440
URL: https://issues.apache.org/jira/browse/LANG-440
Project: Commons Lang
Issue Type: Bug
Affects Versions: 2.4
Reporter: Robert Scholte
Fix For: 3.0
The provided JUnit-tests test with wrong expected values
{code:title= original DateUtilsTest.java}
dateAmPm1 = dateTimeParser.parse("February 3, 2002 01:10:00.000");
dateAmPm2 = dateTimeParser.parse("February 3, 2002 11:10:00.000");
dateAmPm3 = dateTimeParser.parse("February 3, 2002 13:10:00.000");
dateAmPm4 = dateTimeParser.parse("February 3, 2002 19:10:00.000");
assertEquals("truncate ampm-1 failed",
dateTimeParser.parse("February 3, 2002 00:00:00.000"),
DateUtils.round(dateAmPm1, Calendar.AM_PM));
assertEquals("truncate ampm-2 failed",
dateTimeParser.parse("February 4, 2002 00:00:00.000"),
DateUtils.round(dateAmPm2, Calendar.AM_PM));
assertEquals("truncate ampm-3 failed",
dateTimeParser.parse("February 3, 2002 12:00:00.000"),
DateUtils.round(dateAmPm3, Calendar.AM_PM));
assertEquals("truncate ampm-4 failed",
dateTimeParser.parse("February 4, 2002 12:00:00.000"),
DateUtils.round(dateAmPm4, Calendar.AM_PM));
{code}
but expected values must be
{code}
dateTimeParser.parse("February 3, 2002 00:00:00.000");
dateTimeParser.parse("February 3, 2002 12:00:00.000");
dateTimeParser.parse("February 3, 2002 12:00:00.000");
dateTimeParser.parse("February 4, 2002 00:00:00.000");
{code}
Also in the junit-comment the word 'truncate' must be replaced with 'round'
