GCOV Coverage analysis for C/C++ doesn't show

[mkilivan (Murat)]

I couldn’t get SonarQube Code Coverage analysis to show coverage.

Sonar Scanner: 5.0.1
SonarQube Server: 9.9.0
gcovr 5.2

The project is very similar to this example:
linux-cmake-gcovr-gh-actions-sc

Steps:

• cmake configure
• "${SONAR_BUILD_WRAPPER_CMD} cmake --build ...
• ctest
• gcovr --root ${SOURCE_DIR} --print-summary --sonarqube -o coverage.xml .

Analysis

sonar-scanner \
  --define sonar.cfamily.build-wrapper-output="${BUILD_WRAPPER_OUT_DIR}" \
  --define project.settings=sonar-project.properties \
  --define sonar.cfamily.gcov.reportsPath=${BUILD_DIR}

Has anyone encountered a similar issue with SonarQube Code Coverage analysis not displaying coverage, and if so, are there any suggestions or solutions to resolve this problem?

Hi @mkilivan and welcome to the community!

It seems to me that you are trying to use sonar.cfamily.gcov.reportsPath property in conjunction with generic SonarQube XML files. .gcov and SonarQube-compatible XML are different formats for test coverage information, and they have to be specified using different scanner properties:

• sonar.cfamily.gcov.reportsPath expects a directory that contains .gcov files generated using the gcov tool. An example for using this property is available here. Note that this example doesn’t use gcovr.
• sonar.coverageReportPaths expects a generic SonarQube XML test data file. One common way to generate such a file for C and C++ is to use gcovr’s --sonarqube flag. An example for using this property is available here.

Since you have already generated a coverage.xml file using gcovr, I would suggest using the sonar.coverageReportPaths property instead of sonar.cfamily.gcov.reportsPath.

I hope this helps and let us know if you have any further questions!

Best regards,
Michael

Thank you Michael, using sonar.coverageReportPaths property fixed the issue.

Many thanks!
