1. File List
The file list shows all the files in your project, sortable by six different columns: grade, filename, number of issues, code duplication, complexity, and code coverage. There is also a search filter available.
This allows you to keep track or focus some of your time on files with low coverage, high complexity, too many issues, or simply a lot of duplication that could be refactored.
When you click in a filename it opens the File detail.
2. File detail
The file detail starts with a header where you can see a lot of statistical information on the file:
Below that header you will find a tab selector for further information on issues, coverage, and duplication. By default you will see the list of issues in the file. On the right-hand side you can toggle between a list view and the annotated source code.
You can open each issue to get more information on it. For more information about Issues, please refer to Issues.
The coverage tab shows you which lines are covered by tests and which aren't.
As for the duplication tab, here you can find duplicated code and links to its clones.
