Two weeks ago I wrote about code coverage from within Eclipse using djUnit. Since discovering djUnit I've become a huge fan of code coverage in the IDE to improve the TDD process. Since we're going to be using Idea at my current company I looked around and discovered that Clover (commercial software) has both Idea and Eclipse plugins which is what we'll be using. Another really nice coverage tool that is open-source is Emma and as it turns out Emma has an Idea plugin.
