Compare Date objects with different levels of precision

Question

I have a JUnit test that fails because the milliseconds are different. In this case I don\'t care about the milliseconds. How can I change the precision of the assert to i

Answer 1

use AssertJ assertions for Joda-Time (http://joel-costigliola.github.io/assertj/assertj-joda-time.html)

import static org.assertj.jodatime.api.Assertions.assertThat;
import org.joda.time.DateTime;

assertThat(new DateTime(dateOne.getTime())).isEqualToIgnoringMillis(new DateTime(dateTwo.getTime()));

the test failing message is more readable

java.lang.AssertionError: 
Expecting:
  <2014-07-28T08:00:00.000+08:00>
to have same year, month, day, hour, minute and second as:
  <2014-07-28T08:10:00.000+08:00>
but had not.
