When drilling down from the project dashboard, the resource viewer is the ultimate place to view detailed information on a given resource: file or unit tests file. The power of the tool comes from the fact that the resources can be viewed according to different axes of quality.
Viewing Source Code File
When drilling down into measures, you will eventually reach the file level and will be able to browse the source code.
Sonar is shipped with 6 default tabs. Depending on the plugins you have installed, other tabs may be displayed.
In the middle, a contextualized header depending on the selected tab
At the bottom, the code source contextualized, depending on the chosen tab. A pagination system is in place (3,000 lines) to avoid performance issues on huge files.
This tab shows source code with highlighted syntax.
It is also possible to view SCM information on this page by using the SCM Activity Plugin
The coverage tab shows the source code annotated with extra information and colors showing the code coverage. In the first column appears the number of hit of the line during execution of unit tests and in the second one the number of conditions covered on the line along with the number of conditions to cover.
A drop down list enables to filter the information to show on the viewer
When code coverage by integration tests is collected with help of Jacoco, all IT coverage measures are displayed in this "Coverage" tab :
The violations to display can be filtered by coding rule, severity, etc.
Thanks to the Time changes... list box, you can only display new violations that have been added for a timespan. See Differential Views for more information.
Only the source code around the violations is displayed. If necessary for investigation purpose, you can display the full source code by ticking the Full source box.
You can directly manage the violations and their related reviews: comment, assign, link o an action plan, etc. See Violations and Reviews for more information.
The duplications tab shows every duplicated chunk of code within a class and the name of the other class it is duplicated with.
The Dependencies tab shows all incoming and outgoing dependencies on the chosen file.
The LCOM4 tab shows blocks of resources within a class that have tight relationship. Having more that one block here probably means that the class is assuming more than one responsibility.
Viewing Unit Tests File
When drilling down into unit tests execution measures, you will eventually reach the unit test class level:
This tab simply displays the source code of your unit test class:
This tab displays the result of the unit tests belonging to the unit tests class.
In case the test failed or was in error, the reason of the issue can be viewed.
This tab displays the violations on the unit tests:
