There are a ton of benfits from using Xdebug, from saving time to being able to profile scripts, it really is an essential development tool. If you haven’t tried it out you really owe it to yourself to give it a whirl. But enough gushing about Xdebug.

The code coverage reports in the the test suite provide quick svn diff like coverage reports of lines executed on the test subject during your test. The subject is auto-magically derived from the filename of the test. Yet another situation where adhering to naming conventions is beneficial. The code coverage report highlights what lines in the subject class were executed and what lines were not. A summary percentile is also provided, giving you an instant look at how much coverage your tests are providing.
