Test Framework

Member of the xUnit family of test frameworks

Mock Objects

DbUnit

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

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

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)
