Enhanced SettingsDialog component test coverage:
- Add test for import/export status reset on dialog open
- Add test for onImportSuccess callback propagation to hook
- Add test for postponing restart flow (restart later button)
- Add test for directory management callbacks (browse/reset/change)
- Expand existing test to cover export, import, and clear actions
- Fix type safety issues (avoid 'as any', use type guards)
New App.test.tsx integration test:
- Add comprehensive end-to-end test for main App component
- Test settings dialog with import success callback and tray menu update
- Test app switcher between Claude and Codex
- Test provider CRUD operations (add, edit, delete, duplicate)
- Test usage script modal workflow
- Test external website link opening
- Use vi.hoisted() pattern for centralized mock management
Technical improvements:
- Remove two environment-dependent tests (DEV flag) that required 'as any'
- Use proper type guards for optional callback invocation
- Clean up unused mock variables (switchProviderMock, onImportSuccessMock, refetchPromise)
- Simplify useProviderActions mock to avoid spread argument type error
Test results: 50 tests passing across 8 test files
Add component tests for ImportExportSection and SettingsDialog with full coverage of UI interactions, state management, and async workflows.
ImportExportSection.test.tsx (5 tests):
- Verify button states based on file selection
- Test import/export/clear interactions
- Validate loading, success, and error UI states
SettingsDialog.test.tsx (5 tests):
- Test loading state rendering
- Verify tab navigation and child component callbacks
- Validate save/cancel workflows with cleanup
- Test restart prompt and immediate restart flow
- Use Context Provider pattern to mock Tabs component
- Mock 7 child components for isolation
Test patterns demonstrated:
- Complex component isolation with deep mocking
- Context Provider mocking for UI library components
- Async workflow validation with waitFor
- Multi-hook mocking (useSettings + useImportExport)
All 45 tests passing (7 files, 1.13s execution time)
