SonarCloud with Googletest and CMake on GitHub Actions - c

Question

Introduction
Currently, I'm working on a C project with CMake and Googletest.
My project is on a GitHub repo.
I have configured my GitHub Workflow like this:
name: Build
on:
push:
branches:
- main
pull_request:
types: [opened, synchronize, reopened]
jobs:
build:
name: Build
runs-on: ubuntu-latest
env:
BUILD_WRAPPER_OUT_DIR: build_wrapper_output_directory # Directory where build-wrapper output will be placed
steps:
- uses: actions/checkout#v3
with:
submodules: recursive
fetch-depth: 0 # Shallow clones should be disabled for a better relevancy of analysis
- name: Install sonar-scanner and build-wrapper
uses: SonarSource/sonarcloud-github-c-cpp#v1
- name: Run build-wrapper
run: |
mkdir build
cmake -S . -B build
build-wrapper-linux-x86-64 --out-dir ${{ env.BUILD_WRAPPER_OUT_DIR }} cmake --build build/ --config Release
- name: Run sonar-scanner
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
SONAR_TOKEN: ${{ secrets.SONARCLOUD_TOKEN }} # Put the name of your token here
run: |
sonar-scanner --define sonar.cfamily.build-wrapper-output="${{ env.BUILD_WRAPPER_OUT_DIR }}"
Problem
The problem, when I execute it the SonarCloud show 0% test coverage :
Question
Does someone know how we can configure the GitHub Actions for SonarCloud to include Googletest?

In your current configuration, the coverage data is not being generated.
Follow this official guide to generate and report coverage data:
C/C++/Objective-C Test Coverage
Apparently, for your use case, the most suitable example seems to be linux-cmake-gcovr-gh-actions-sc. It uses gcovr which generates the coverage report in the SonarQube format which you can send to SonarCloud.
For this, you need to update your CMakeFiles.txt and build.yml files according to these:
CMakeLists.txt: https://github.com/sonarsource-cfamily-examples/linux-cmake-gcovr-gh-actions-sc/blob/main/CMakeLists.txt
build.yml: https://github.com/sonarsource-cfamily-examples/linux-cmake-gcovr-gh-actions-sc/blob/main/.github/workflows/build.yml
Also, see gcovr's Out-of-Source Builds with CMake.
