3 failures in fallback.cliproxyapi-matrix.test.ts:
- Root cause: leaked spyOn(getMainSessionID) in
tool-execute-before-session-notification.test.ts was never restored,
poisoning module state for subsequent tests in the same worker
- Added mockRestore() call and _resetModelFallbackForTesting in afterEach
3 failures in background-agent/manager.test.ts:
- Root cause: connected-providers-cache memConnected/memProviderModels
persisted across test files, making isReachable() skip fallback
candidates in retry tests
- Added mock.module for connected-providers-cache at file level
- Added _resetMemCacheForTesting export and global beforeEach cleanup
Full suite: 4638/4638 pass, 0 fail
- model-fallback hook: mock selectFallbackProvider and add _resetForTesting()
to test-setup.ts to clear module-level state between files
- fallback-retry-handler: add afterAll(mock.restore) and use mockReturnValueOnce
to prevent connected-providers mock leaking to subsequent test files
- opencode-config-dir: use win32.join for Windows APPDATA path construction
so tests pass on macOS (path.join uses POSIX semantics regardless of
process.platform override)
- system-loaded-version: use resolveSymlink from file-utils instead of
realpathSync to handle macOS /var -> /private/var symlink consistently
All 4456 tests pass (0 failures) on full bun test suite.
