Examples of org.junit.ComparisonFailure

org.junit.ComparisonFailure
Thrown when an {@link org.junit.Assert#assertEquals(Object,Object) assertEquals(String, String)} fails.Create and throw a ComparisonFailure manually if you want to show users the difference between two complex strings.
Inspired by a patch from Alex Chaffee (alex@purpletech.com) @since 4.0
