This refactors the Qt/.NET native test harnesses to use shared setup
code on both the C++ and managed sides, and hooks additional sources
into the generated CMake project.
- Introduce QtTestSetupBase (C++) to encapsulate common host bootstrap:
locating the managed test assembly, running the app (sync/async),
waiting for readiness, initializing the Qt/.NET adapter and
finalizing/unloading the host.
- Add BridgeExitCode enum (C++) and mirror it as ExitCode (C#) with
ExitCodeHelper so managed tests can report bridge infrastructure
failures with descriptive messages. QTest keeps using exit code 1
for test failures; bridge errors use 101+.
- Add QtQuickTestSetup (C++), a reusable QtQuickTest setup class with
overridable hooks (before/after applicationAvailable, qmlEngineAvailable
and cleanupTestCase) and centralized Ready/Finalize handling.
- Introduce ManagedTestBase (C#) to DRY TempProject creation, native
build, and configuration for QtTest/QtQuickTest, including CMake
injection and shared header/source replacement.
- Update Test_QtTest and Test_QtQuickTest to inherit from
ManagedTestBase, removing duplicated TempProject and build/run
boilerplate.
- Add CMake.InjectQtSourcesTargets helper (C#) to inject native
headers/sources into the generated CMakeLists.txt via an MSBuild
CodeTaskFactory task that patches the qt_add_executable() source list.
- Extend the test .csproj to copy the shared C++ setup files to the
output so they can be picked up by ReplaceGeneratedFiles.
- Dump the build output to the test output pane if the C++ build fails.
