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 15 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 rather than an Exception. You can read more about (not) catching Error in this question. Are you sure you don't just want a test - if ( variableName == "1")? NB if you are testing unit-test helper code, like a matcher, it might make sense to catch the AssertionError. share|improve this answer edited Jan 19 at 15:09 gkephorus 653615 answered Apr 16 '15 at 10:39 J Richard Snape 14.6k42352 When one wants to see if a un

Answers Walid Aly, Java C C# VB.NET PHP JavaScriptWritten 92w agoI found this online"You should not encounter any AssertionErrors through normal execution of a properly written program. Such errors should only indicate bugs in the implementation. As a result, you should never catch an AssertionError. Rather, you should allow the program to terminate when the error occurs, so you can see the error message, then you should locate and fix the source of the problem. Since application users can choose not to enable assertions at runtime, you should not use the assert statement to indicate runtime problems in production code. Rather, you should use the exception mechanism for this purpose."89 ViewsRelated QuestionsMore Answers BelowIs it bad practice to catch null pointer exceptions in Java?Is it bad practice to retry three times before failing when applying try-catch?Should JUnit fail() and AssertionError allow a nested exception?Some mid-level programming practice in Java?
