Subject [jira] [Updated] (COLLECTIONS-373) Bug in class#ListOrderedSet with reproducible JUnit test
Date Sun, 03 Apr 2011 08:12:05 GMT

Sai Zhang updated COLLECTIONS-373:
----------------------------------

    Description: 
Hi all:

I am writing an automated bug finding tool, and using
Apache Commons Collections as an experimental subject
for evaluation.

The tool creates executable JUnit tests as well as
explanatory code comments. I attached one bug-revealing
test as follows. Could you please kindly check it, to
see if it is a real bug or not? 

Also, it would be tremendous helpful if you could give
some feedback and suggestion on the generated code comments?
>From the perspective of developers who are relatively familiar
with the code,
is the automatically-inferred comment useful in understanding
the generated test? is the comment helpful in bug fixing?

Your suggestion will help us improve the tool.

Please see attachment for the failed test. A little explaination
on the generated code comments in the failed test

//explaination:
//Test passes if var53 is: (java.lang.Boolean)false  ===> means: 
//     test passes if var52 is not added to var28 (only in that case, var53 is false)
boolean var53 = var28.add((java.lang.Object)var52);
