Bryan Pendleton commented on DERBY-6164:
----------------------------------------
That's great, it looks like you have the tools configured successfully now.
The next step is to start reading the reports at
http://dbtg.foundry.sun.com/derby/test/coverage/
which are from runs that perform the full Derby test suite.
Looking at those runs, see if you can identify some areas of the Derby code
base that
have low coverage; those are the areas where we are trying to write new tests to
improve our test coverage.
Many areas of the Derby code base are quite well covered by our test suite, but
we
can still identify substantial portions of the code that are not well-tested,
and our
goal this summer is to find some of those areas and address them.
For example, consider this class:
http://dbtg.foundry.sun.com/derby/test/coverage/_files/6d.html
This is the report for IndexStatisticsDaemonImpl.java. This is a quite new
class in the
Derby code base, I believe, and although we have a number of test cases for it,
perhaps there are additional test cases that can be written to increase the
coverage.
Have you drafted your proposal to Google?

> Key: DERBY-6164
> URL: https://issues.apache.org/jira/browse/DERBY-6164
> Project: Derby
> Issue Type: Task
> Components: Test
> Reporter: Bryan Pendleton
> Assignee: Bryan Pendleton
> Priority: Minor
> Labels: gsoc2013
>
> This year's edition of Google Summer of Code includes, once again, the Apache
> Software Foundation.
> For the Derby project, I'm offering to mentor a student on the tasks
> described here.
> For this project, you are required to have some basic knowledge of JUnit and
> of how code coverage works.
> Currently some packages of Derby have poor code coverage. Emma defines the
> minimum acceptable code coverage as 70% and some engineers suggest a minimum
> of 80% is desired.
> Students are invited to look at [1] to get familiar with Emma's code coverage
> reports on Derby.
> The Derby project conducted this effort last year, and substantial
> improvements were made.
> We are looking to continue this process this year, as there are still areas
> of the Derby code base where code coverage could be substantially improved.
> The candidate students are also expected to come up with their own schedule
> for the tests they plan on creating and to discuss this schedule publicly on
> the mailing list.
> After a student applies, a small interview will be conducted via email as
> part of the ASF's evaluation process.
