What's the difference? java testing junit share|improve this question edited Aug 12 '10 at 13:30 asked Aug 6 '10 at 17:00 froadie 24.1k46117190 error fault failure add a comment| 4 Answers 4 active oldest votes up vote 78 down vote accepted Ok, I've just noticed a pattern and think I've figured it out (correct me if I'm wrong). It seems to me that failures are when your test cases fail - i.e. your assertions are incorrect. Errors are unexpected errors that occur while trying to actually run the test - exceptions, etc. share|improve this answer answered Aug 6 '10 at 17:05 froadie 24.1k46117190 11 You are correct, sir. –Jesse J Aug 6 '10 at 17:13 4 Though if anything extending java.lang.AssertionError is thrown it will be shown as a test failure instead of a test error. You should consider accepting your own answer because it is correct. –ponzao Aug 12 '10 at 14:15 Yes, that's exactly the difference. And from a pragmatic perspective there is "no difference" -- in that if you get an error or a failure, then you need to fix it. So it was probably a mistake to count "failures" and "errors" separately in JUnit. JUnit 4 combines the two (as explained in an answer below). &ndash

Fault From what I've come to understand, a Fault in this context would be a flaw in the code's written logic. So in this case the Fault would be the fact that the code instructs the computer to start iterating over all elements of v with a start index of 1 instead of the expected 0. Error When running the above method, we always get an Error but in once instance (when v.length == 0), as what we really want is to iterate over all elements of x, but since we're starting with i = 1, that is not really happening. With an empty vector as input, as we don't enter the for loop, so our incorrect code isn't run, meaning that the Error doesn't happen, and everything happens as should in theory. Failure Since our code has a Fault that in execution-time will almost always manifest in a Error, we only have a Failure when we effectively see the incorrect output. Assuming that an Er
