I was recently looking for a unit test coverage analyzer such as JCoverage for a project I’m working on. After reviewing several tools I discovered an amazing free tool called EclEmma.
I’ve used JCoverage in the past and while it’s HTML based reports are useful for project managers they are less so for developers. This tool essentially gives you the same information, but directly in Eclipse. You simply run the analyzer on either a single class or a set of classes and viola… you have your coverage report.
It even color codes each line of code within your editor window.
Use the http://update.eclemma.org/ update site to install EclEmma.
