 | Critical Cxx Plugin does not run any tests or produce coverage results, reports thus must be created a priori |
Unit Test
Supported Formats
Only xunit complaint
Coverage
Supported Format
Cobertura and Bullseye (http://www.bullseye.com/) XML formats are supported for > 0.2 versions. Previous versions support only Cobertura, and sonar.cxx.gcovr.reportPath needed to be set.
Gcov / gcovr
- Make sure to compile and link with the --coverage-flag. Disable optimizations and switch on debugging.
- Execute your application / your tests. This will generate .gcda-files.
- Collect the coverage information and generate the report using gcovr:
Bullseye
Bullseye coverage tool is now supported, the command 'covxml' can be used to create the XML report. Once xml reports is available it can be imported using the properties sonar.cxx.coverage.reportPath and sonar.cxx.coverage.itReportPath.
Notes about coverage display in sonar:
Sonar <3.2 provides metrics for line coverage and branch coverage. Bullseye users have function and branch/decision coverage instead, the cxx plugin coverts the second directly into branch coverage however line coverage is far more complex and cannot be correlated directly into function coverage.
Line coverage imported from a bullseye report means than function coverage + line branch coverage ( this second occurs since sonar will not display branch coverage if there isn't a line it associated with it). This means also that overall coverage will be affect in sonar and cannot be compared directly to bullseye results. The following pictures illustrate this for a small example project.
