A Tag Cloud or 'weighted list' is a way of visually representing information.

In Clover, 'Coverage Clouds' provide an instant overview of your entire project and individual packages, enabling you to identify areas of your code that pose the highest risks or shortcomings.

Each Coverage Cloud displays two metrics per Java or Groovy class. One metric is displayed via the font size, and the other via the font color. Each attribute has relative weighting across the entire project. Classes are sorted alphabetically.

Tool tips on each class name provide you with the real values for each metric.

Risks

The Project Risks / Package Risks Cloud highlights those classes that are the most complex, yet are the least covered by your tests. The larger and redder the class, the greater the risk that class poses for your project or package. Package risk clouds can be toggled to include or exclude classes in sub-packages.

Quick Wins

This Cloud highlights the "low hanging coverage fruit" of your project or package. You will achieve the greatest increase in overall project coverage by covering the largest, reddest classes first. Package Quick Win clouds can be toggled to include or exclude classes in sub-packages.
