Assertion for Date

[A Kumar]

Hi all,

I am writing test cases and i wish to compare the date in the database

to what i entered in the DTO of the object...It is givind me errors..

I wish to comapre two dates...

Is there an assertionEquals or assertionTrue method or any other method..

that wud allow me..to do it. with the dates as arguments?

Thx in advance,
A Kumar.

As Date implements the equals method, assertEquals(Object, Object) should work fine...

Hi,

I will try to work out this way..and get back to u...

But is it ok..if I compare the two dates...

int val= Date1.compareToDate(Date2)

assertEquals(1,val );

Thx

I would rather do something like this:

assertTrue(date1.before(date2));

...or, if you want to test for equality:

assertTrue(date1.equals(date2));

The other thing to watch with dates is the precision. ALl of the methods post about (that check for equality) require the dates to be the same to the millisecond. If you want to check just the date part or the time part, you can write a custom assertion. For example,

public void assertDay(Date actual, int month, int day, int year) {
  Calendar cal = new GregorianCalendar();
  cal.setTime(actual);
 
  assertEquals("month", month, cal.get(Calendar.MONTH));
  assertEquals("day", month, cal.get(Calendar.DATE));
  assertEquals("year", month, cal.get(Calendar.YEAR));
}

I favor assertEquals(date1, date2);
over assertTrue(date1.equals(date2));
because it gives clearer output on an assertion failure.
