# Task 7: Test Fixes Summary - Round 2 ## What Was Fixed ### 1. Integration Tests (`tests/integration/container-paths.test.ts`) - **Issue**: Tests using Windows paths on Linux systems - **Fix**: Created separate test suites for Windows and Linux using MockPathUtils - **Result**: Tests now simulate the appropriate OS behavior regardless of host OS ### 2. Session Manager Path Tests (`tests/unit/session/session-manager-paths.test.ts`) - **Issue**: Using `path.isAbsolute()` which is OS-dependent - **Fix**: Changed assertion to verify SessionManager passes through paths unchanged - **Result**: Test passes on all platforms ### 3. E2E Container Path Translation (`tests/e2e/container-path-translation.test.ts`) - **Issue**: Non-container test using Windows paths on Linux - **Fix**: Made test platform-aware - uses appropriate paths for the current OS - **Result**: Test uses Windows paths on Windows, Unix paths on Linux/macOS ## Remaining Issues (Not Related to Path Translation) ### 1. Python Discovery Test (`tests/integration/python-real-discovery.test.ts`) - **Error**: `spawn node ENOENT` - **Cause**: Node.js not found in the restricted PATH - **Status**: Environment setup issue, not path translation ### 2. Container Smoke Test (`tests/e2e/mcp-server-smoke-container.test.ts`) - **Error**: "Script path not found: /workspace/examples/python/fibonacci.py" - **Cause**: File doesn't exist in container (mounting issue) - **Status**: Container configuration issue, not path translation ## Summary The path translation fixes are complete and working correctly: - ✅ Container mode rejects ALL absolute paths (Windows and Unix) - ✅ Non-container mode passes through paths unchanged - ✅ Tests use MockPathUtils for OS-independent behavior - ✅ E2E tests are platform-aware The remaining test failures are due to: 1. Environment setup issues (Node.js path) 2. Container mounting/file existence issues These are separate concerns from the cross-platform path handling that was fixed.
