Custom message when JUnit assert fails

Question

I want to include a line separator (horizontal line of hyphens) before and after the assert failure message so that they are more visible and can be easily found in log.

Is there I can do this in a way that it shows up for when any assert fails? Naive way of doing this of course is to add the line separator strings to each assertEquals method.

Answer 1

you can do it with test listener. Create test listener extention from RunListener RunListener overide method

public void testFailure(Failure failure) throws Exception

Called when an atomic test fails, or when a listener throws an exception.
