CTest Executable Path Issue +**Problem:** CTest looked for executables in `bin/` root, but CMake placed them in `bin/MinSizeRel/`, `bin/RelWithDebInfo/` subdirectories. + +**Resolution:** Run CTest from `tests/` subdirectory where `CTestTestfile.cmake` is located. + +### 2. Qt Platform Plugin Errors +**Problem:** 7 tests failed with "Could not load the Qt platform plugin 'xcb'" in headless Docker. + +**Resolution:** Set `QT_QPA_PLATFORM=offscreen` environment variable to use Qt's offscreen rendering platform. + +### 3. Migration Tests Not Found +**Problem:** `CTest -R migration_tests` returned "No tests were found" despite test file existing. + +**Resolution:** Tests are registered via `gtest_discover_tests()` which generates `migration_tests[1]_tests.cmake`. Running CTest from correct directory resolves this. + +--- + +## Verification Checklist + +- [x] Full build completes (12 build groups + RTI) +- [x] All test executables created +- [x] CTest suite runs successfully +- [x] 100% test pass rate achieved +- [x] ArcGIS 300 symbology builds correctly +- [x] GUI tests pass with offscreen platform +- [x] No critical migration errors +- [x] All Qt6 API migrations applied +- [x] Build script issues resolved +- [x] CMake configuration issues resolved + +--- + +## Recommendations + +1. **For Future Builds:** Always use `QT_QPA_PLATFORM=offscreen` when running tests in headless Docker environments. + +2. **For CI/CD:** Consider adding the offscreen platform variable to the Docker build script's test execution section. + +3. **For Documentation:** Update developer onboarding docs to note the Qt6 API changes, especially: + - QStringRef → QStringView + - QTouchDevice → QInputDevice + - QtConcurrent::run signature change + +4. **For Testing:** Run CTest from the `tests/` subdirectory to ensure correct executable path resolution. + +--- + +## Conclusion + +The Qt6 migration is **production-ready**. All tests pass, all build groups compile successfully, and ArcGIS 300 symbology support is fully functional.
