This seems like a gross misuse of Assert which is meant for Unit Testing –Dragondraikk Apr 16 '15 at 10:25 add a comment| 3 Answers 3 active oldest votes up vote 16 down vote accepted You have almost answered your own question. Your catch block will not catch the AssertionError that the Assert throws if it fails, because it is an Error (or, more specifically, it extends java.lang.Error). See the docs for more information on this. Your catch block only catches Throwable objects that extend java.lang.Exception If you really want to catch it - you need to use catch (AssertionError e) { ... However, as others have mentioned, this is a very unusual way to use assertions - they should usually pass and if they fail it is very unusual for you to want to carry on program execution. That's why the failure throws an Error ra

Or at least you will run into people in your career who take a dim view of using exceptions for program flow control. How about: Assert.assertTrue((someObject.getValue1().equals(expectedValue1) || (someObject.getValue2().equals(expectedValue2)); share|improve this answer answered Aug 14 '13 at 1:23 Aquilon 1589 Thanks, @Aquilon! In this case, my asserts are buried in a verification method that takes as parameters the properties of the object I need to assert for. So I can't really pass two expected values for the same property without changing the method's signature. So I am sticking to the original try...catch solution while noting

One of the issues that we are running into is that the code in the module, has 'asserts'. Now, because of this there are quite a few occasions when we have seen assertion error the java.lang.AssertionError being thrown. Our problem is that in our application, we are catching java.lang.Exception and on catching the exception, we do some additional logic. Now, since the AssertionError extends from Throwable, this never gets caught and we are not seeing the expected behaviour in our application. My question is, Is it a right practice assertion error in to throw AssertionError in production level code. Are applications supposed to catch them? I wanted to know this so that we can either change the code in the module that we are integrating our application with, or just start catching Throwable instead of Exception in our application, so that even the AssertionError is caught. Thank you. [My Blog] [JavaRanch Journal] Ernest Friedman-Hill author and iconoclast Marshal Posts: 24212 35 I like... posted 10 years ago AssertionErrors are thrown when assertions fail. Assertions fail because something the programmer believed to be true turns out not to be true. That means there is a bug in the code. If you see an AssertionError, find and fix the source of the problem right away! If you catch an AssertionError and continue, then you have no idea whether the application is working correctly anymore. From that point forward, it's entirely possible that everything the application does is garbage. [Jess in Action][AskingGoodQuestions] Jesper de Jong Ja
