Question

I have a JUnit test that is as follows:

@Test
public void testToDatabaseString() {
  DateConvertor convertor = new DateConvertor();
  Date date = convertor.convert("20/07/1984:00:00:00:00");
  String convertedDate = convertor.toDatabaseString(date);

  assertEquals("to_date('20/07/1984:00:00:00:00', 'DD/MM/YYYY HH24:MI:SS')",convertedDate);
}

The test fails stating:

org.junit.ComparisonFailure: expected:<to_date('20/07/1984[00:]00:00:00', 'DD/MM/YY...> but was:<to_date('20/07/1984[ ]00:00:00', 'DD/MM/YY...>

Of particular interest is why the expected value is:

to_date('20/07/1984[00:]00:00:00', etc…

when my string literal in the test is clearly:

"to_date('20/07/1984:00:00:00:00', etc…

Can anyone explain this? Why does it add "[00:]"? Appreciate the help.

Answer 1

The square brackets are emphasising the difference between the expected string and the actual string.

JUnit put the square brackets around the :00 to emphasise that that is what’s in the expected string and not in the actual string. There are square brackets around the space in the actual string for the same reason.
