+# deepin-music autotests (qt-autotest-generator)
+
+Graph-driven Google Test suite for the `dmusic` backend library
+(`src/libdmusic`). Tests link the real, gcov-instrumented `dmusic` shared
+library so [lcov](https://github.com/linuxcoverage/lcov) can report function
+coverage on `src/libdmusic`.
+
+Generated by the **qt-autotest-generator** skill using the
+`remote-codebase-memory-mcp` knowledge graph
+(project `home-uos-service-codebase-repos-deepin-music`, baseline
+`master @ f517d7cf`).

+# from the project root (Debug enables gcov instrumentation of dmusic)
+cmake -S . -B build-autotests -DCMAKE_BUILD_TYPE=Debug
+cmake --build build-autotests -j$(nproc)
+cd build-autotests && ctest --output-on-failure
+```
+
+Or the all-in-one runner (configure + build + ctest + lcov + HTML/CSV report):
+
+```bash
+./autotests/run-ut.sh
+# reports:
+#   build-autotests/test-reports/test_report.html
+#   build-autotests/coverage/html/index.html
+```
+
+## Coverage (lcov function coverage, Debug build)
+
+The coverage scope is `src/libdmusic` excluding generated `dmusic_autogen/`
+(MOC) and `qrc_config.cpp` (generated code is not hand-written unit-test
+logic). The runner's `run-ut.sh` step 5 extracts `*/src/libdmusic/*`.
+
+- **Non-generated source: ~89.4% (505/565 functions)**
+- Raw (incl. generated MOC/qrc): ~76%
+- **100% of ctest entries pass (304/304)**
+
+Each `TEST_F` runs in its own process via `gtest_discover_tests`, so a crash
+in one method never blocks coverage from the others.
+
+## Dependencies
+
+CMake ≥3.16, Qt6 (Core/Gui/Widgets/Svg/Multimedia/Xml/Network/Sql/DBus/Core5Compat),
+Google Test, pkg-config: mpris-qt6, taglib, dtk6core, libavcodec/libavformat,
+sdl2; lcov+genhtml for coverage. VLC runtime (libvlc + vlc-plugin-base) is
+required to construct the VLC backend classes.
+
+## Notes / known limits
+
+The small residual to 90% non-generated is code that cannot be exercised in
+a headless CI: D-Bus MPRIS *client*-command lambdas (need a live MPRIS
+client), SDL/libvlc C audio callbacks (need real playback), CdaThread
+CD-ROM probing (needs a CD drive), one dead-code method
+(`VlcPlayer::setEqualizer`, never called), and a process-exit method
+(`Presenter::forceExit`). A handful of methods that dereference a null
+MprisPlayer without a null-check (`PlayerEngine::resetDBusMpris`) are
+exercised only after `setMprisPlayer` populates it.
