Worked on stabilizing the DirectXShaderCompiler test harness by addressing a resource lifecycle issue in the ShaderOpTest component. The solution involved refactoring HANDLE management, moving resource creation to the test class constructor and ensuring proper cleanup in the destructor. This approach eliminated resource leaks and improved the reliability of unit tests, reducing flaky behavior during repeated test runs. The work focused on robust resource management and careful use of C++ features to support maintainable and reliable testing infrastructure. By enhancing the test harness in the libsdl-org/DirectXShaderCompiler repository, the changes contributed to more dependable ship readiness for shader compilation features.
