From 8ef6529c0c728de01e0658e2a5a9288681ca207d Mon Sep 17 00:00:00 2001 From: twi-devel Date: Thu, 22 Oct 2026 17:17:39 +0200 Subject: [PATCH] feat: Add LCOV coverage support for Jenkins CI - Add ENABLE_COVERAGE CMake option with gcov flags - Create collect-coverage.sh script for LCOV workflow - Add Qt6 test files with QTest framework - Update Jenkinsfile with Coverage stage (main/master/coverage.*) - Update CI Docker image with lcov and genhtml packages - Add .gitignore entries for coverage artifacts - Add COVERAGE.md documentation Coverage workflow: 1. Configure with -DENABLE_COVERAGE=ON 2. Build and run tests to generate .gcda/.gcno files 3. Collect coverage with lcov 4. Filter out Qt/system libraries 5. Generate HTML report and lcov.info for Jenkins Jenkins publishes coverage/lcov.info using Coverage Plugin. Coverage stage only runs on protected branches.
