To better understand how Sonar works and to be in a position to better evaluate code coverage results, it is necessary to take a closer look at how code coverage tools analyze tests and calculate total coverage. The result of the coverage analysis process, although expressed as a single percentage number in Sonar, is based on many different coverage metrics.
Next, we will examine four fundamental coverage metrics used by all code coverage tools supported by Sonar:
- Statement coverage
