Prior to version 2.5, Sonar was really useful to assess application’s technical debt but was not so handy to manage evolution over time. In Sonar 2.5 was added the ability to see metrics evolution and monitor the apparition of new violations over a period of time or since an event. A similar functionality has now been added with version 2.7 for code coverage by unit tests on new / updated source code. It is now possible to follow what percentage of changed code over a period of time is covered by unit tests.
Tighter integration with SCM data
By using the SCM Activity extension, Sonar can retrieve information from the SCM and display them along with the source code.
Coverage of new/updated source code
Monitoring code coverage is crucial to understand the risks associated to changes. But how to do this efficiently in the context of a big legacy application with very low coverage ? All the efforts done to increase coverage are going to be largely diluted and this is going to be almost impossible to make a difference. This is why we added the ability to also monitor the coverage on newly added / updated source code over a period or since an event to track what code was added and is not enough tested.

Better Coverage viewer
Instead of showing the percentage of branches covered, Sonar now displays both the number of covered branches and the total number of branches
And you have the option to filter only the coverage information you want to see
