[jira] [Created] (COLLECTIONS-373) Bug in class#ListOrderedSet with
reproducible JUnit test
Bug in class#ListOrderedSet with reproducible JUnit test
--------------------------------------------------------
Key: COLLECTIONS-373
URL: https://issues.apache.org/jira/browse/COLLECTIONS-373
Project: Commons Collections
Issue Type: Bug
Affects Versions: 3.2
Environment: jdk 1.6.x
Reporter: Sai Zhang
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?
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.

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?
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.

[jira] [Updated] (COLLECTIONS-373) Bug in class#ListOrderedSet with
reproducible JUnit test

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)

[jira] [Commented] (COLLECTIONS-373) Bug in class#ListOrderedSet
with reproducible JUnit test
Posted by "Sai Zhang (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/COLLECTIONS-373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086724#comment-13086724 ]
Sai Zhang commented on COLLECTIONS-373:
---------------------------------------
Hi,
Here is the latest output of our documentation inference tool. It renames all
variable names and (hopefully) makes the test easier to read.
The comments generated by our research tool are shown in the form of:
{code}
//Test passes if: xxxx (it indicates changes that will make a failed test pass)
{code}
Each piece of comments (not the combination of them) provides a way to correct the failed test.
We hope such additional information will help developers understand/fix the test faster/better.
So, it would be great if anyone can take a look at the reported bug to:
(1) confirm is it a real bug?
(2) is such comment information useful? If not, please give us feedback so we can do our best
to improve our tool!
Thank you!
-Sai

> Bug in class#ListOrderedSet with reproducible JUnit test
> --------------------------------------------------------
>
> Key: COLLECTIONS-373
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-373
> Project: Commons Collections
> Issue Type: Bug
> Affects Versions: 3.2
> Environment: jdk 1.6.x
> Reporter: Sai Zhang
> Labels: patch
> Attachments: ApacheListOrderSet_Documented_Test.java
>
>
> 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);
