Sebastian Bergmann's Blog:
Copy & Paste Detection in PHPUnit 3.2
August 22, 2007 @ 09:31:00

Sebastian Bergmann spotlights another feature of the upcoming PHPUnit version 3.2 - the inclusion of a Project Mess Detector's ability to help find duplicate code.

Duplicate code can be hard to find, especially in a large project. Johann-Peter Hartmann of MAYFLOWER GmbH recently implemented Copy & Paste Detection for PHPUnit's growing set of features that extends its usage scenarios beyond "just unit testing" to a one-stop solution for quality assurance in PHP-based projects.

In his example, Sebastian shows what the response will look like when the tests find duplicate code - giving details like the files involved and the code fragment that was duplicated.

Check out this list in another post on Sebastian's blog for more of the metrics that will be included in the upcoming version.
