In a new post to his blog Sebastian Bergmann talks about a new "dashboard view" that's been added to work with the PHPUnit testing suite - PHP_CodeCoverage. He talks more about what it has to offer:

PHP_CodeCoverage is a library that provides collection, processing, and rendering functionality for PHP code coverage information. Its architecture has support for multiple backends for collecting code coverage information (currently only support for Xdebug is implemented) and for reporting code coverage information (for instance using Clover XML or as an HTML report).

The dashboard shows the code's class coverage distribution, class complexity, top project risks and the least tested methods to help you narrow down potential issues in your application. Here's an example of the output.
