Who I am
Sebastian Bergmann

PHPUnit
Test Framework
Member of the xUnit family of test frameworks

Integration
Selenium RC
phpUnderControl, CruiseControl, Bitten, ...
Even More Cool Stuff :-)
Code Coverage, Software Metrics, and “Mess Detection”
Test Database
Mutation Testing (GSoC07 project)

My Current (Research) Interest
I want to correlate test result information and software metrics with sourcecode history.
Examples
Which { classes | methods | functions | files } are
... commonly changed during a bugfix commit?
... commonly changed at the same time?
Code Coverage
Number of Classes vs. Number of Classes without Tests
Number of Methods vs. Number of Methods without Tests
Lines of (Executable) Code vs. Lines Covered by Tests
Number of Tests vs. Number of Failing Tests

My Current (Research) Interest
Currently @ http://phpunit.de/browser/svn_bug_miner
Written in PHP, data stored in RDBMS
Will be usable with phpUnderControl soon
But I would also like to see this functionality in Trac
Inspired by research at the University of Saarbrücken, Germany (eROSE project)
SVN_Bug_Miner

The End
Thank you for your interest!
These slides will be available shortly on http://sebastian-bergmann.de/talks/.
