The latest version of the popular PHP unit testing tool PHPUnit has officially been released (version 4.0.0) and comes with some nice improvements. In this post to the PHPcc blog Sebastian Bergmann talks about enhancements in one area - code coverage reporting.

One of the highlights of PHPUnit 4.0, which was released last week, is an improvement of the @covers annotation and the addition of the @uses annotation for better code coverage analysis.

He includes a few simple code snippets showing you how the "@covers" annotation has been working and how it can be used in both strict and non-strict modes. He also introduces the "@uses" annotation to define which objects the test is using and how the two interact. He finishes off the post with a mention of the "--strict-coverage" command line flag (or the more general "--strict").
