Implemented complete test runner framework for NativeAOT kernels with QEMU execution, binary protocol over UART, and GitHub Actions CI/CD integration. The system supports both x64 and ARM64 architectures with automated testing, result reporting, and artifact management. Test Runner Components: - Engine: QEMU host implementations (x64/ARM64) with configurable timeout - Framework: In-kernel test API (Assert, TestRunner.Start/Run/Finish) - Protocol: Binary UART messages (0x64-0x69) with Latin1 encoding - Output Handlers: Console (colored), XML (JUnit), multiplexing support Build System Fixes: - Added -DARCH_X64 and -DARCH_ARM64 to GCC compiler flags in Cosmos.Build.GCC.targets - Fixed architecture-specific code compilation (kmain.c now compiles correctly per arch) QEMU Configuration Fixes: - Added -boot d flag to boot from CD-ROM properly - Added -no-reboot flag to prevent boot loops after kernel halt - Both x64 and ARM64 hosts now boot and execute tests successfully VS Code Integration: - Added "dev" mode parameter to debug configurations for visual QEMU testing - Created test tasks for quick HelloWorld testing (x64/ARM64) - Debug configurations for both architectures with proper display settings CI/CD Workflow (.github/workflows/kernel-tests.yml): - Parallel x64/ARM64 testing matrix with Ubuntu + QEMU - Automated test result publishing to PR comments - JUnit XML report generation and artifact uploads - Test summary generation with pass/fail counts - Automatic failure comments with UART debug logs Example Test Kernel: - Cosmos.Kernel.Tests.HelloWorld with 3 passing assertions - Demonstrates test framework API usage - Works on both x64 and ARM64 architectures Documentation: - tests/README.md: Usage guide for developers - .taskmaster/docs/test-runner-prd.txt: Product requirements document - CLAUDE.md: Updated with test workflow and Task Master integration Tests performed: - x64: HelloWorld kernel passes 3/3 tests with QEMU - ARM64: HelloWorld kernel passes 3/3 tests with QEMU (requires UEFI firmware) - Both architectures produce correct UART output and JUnit XML results
