How to calculate code coverage in SonarQube?
- SonarQube doesn't calculate a code coverage. It only displays results provided by other tools. You have to execute a tool which calculates code coverage (e.g. Coverage.py) and next add analysis parameters: sonar.python.coverage.reportPath - a report path of the unit test results
What code coverage tools does sonar use?
- Sonar integrates with the most popular open source code coverage tools ( JaCoCo, Cobetura, Emma ) and the well-known commercial Clover by Attlassian. By default it uses the JaCoCo (Java Code Coverage) engine and you’ll shortly find out why
