Replace the previous dual-parameter approach (app_type/app/appType) with a single required `app: String` parameter across all Tauri commands. This change:
- Introduces unified `parse_app()` helper replacing complex `resolve_app_type()` logic
- Updates all backend commands in config, mcp, and provider modules
- Aligns frontend API calls to use consistent `app` parameter naming
- Simplifies MSW test handlers by removing optional parameter handling
This improves API clarity and reduces parameter ambiguity while maintaining backward compatibility through error handling.
Update test infrastructure to support the dual app type parameter pattern
(app_type enum + app string) introduced in 590be4e:
- Add toast.warning mock for partial-success status handling
- Add syncCurrentProvidersLive mock to test post-import sync behavior
- Update MSW handlers to accept both app_type and app parameters with
fallback resolution (app ?? app_type) across 7 provider endpoints
- Add sync_current_providers_live endpoint mock returning success
This ensures test compatibility during the app_type → app parameter
migration and enables testing of the new partial-success import flow.
- Add vitest/globals to tsconfig.json types array to provide type
definitions for global test functions (describe, it, expect, vi)
- Fix vi.fn type parameter in useDirectorySettings.test.tsx from
<[], Promise<string>> to <() => Promise<string>>
- Remove unused setMcpConfig import from MSW handlers
- Add type assertions for mock.calls access in McpFormModal tests
to resolve union type inference issues
This ensures pnpm typecheck passes without errors while maintaining
test functionality with vitest globals: true configuration.
## MSW Infrastructure Enhancement
- Add 5 MCP API handlers to tests/msw/handlers.ts:
- get_mcp_config: Fetch MCP configuration for app type
- import_mcp_from_claude/codex: Mock import operations (returns count: 1)
- set_mcp_enabled: Toggle MCP server enabled state
- upsert_mcp_server_in_config: Create/update MCP server
- delete_mcp_server_in_config: Remove MCP server
- Add MCP state management to tests/msw/state.ts:
- McpConfigState type with per-app server storage
- Default test data (stdio server for Claude, http server for Codex)
- CRUD functions: getMcpConfig, setMcpServerEnabled, upsertMcpServer, deleteMcpServer
- Immutable state operations with deep cloning
## McpFormModal Component Tests (4 tests)
- Test preset application: Verify ID and config JSON auto-fill from preset selection
- Test conflict detection: Async validation shows warning when syncing to conflicting ID
- Test field sanitization: Verify trim whitespace, split tags, clean URLs before save
- Test validation errors: Block submit and show toast error for invalid stdio config (missing command)
## McpPanel Integration Tests (3 tests)
- Test toggle enabled state: Click toggle button triggers useMcpActions.toggleEnabled with correct params
- Test create server flow: Open form → submit → saveServer called with syncOtherSide option
- Test delete server flow: Click delete → confirm dialog → deleteServer called with ID
## Test Utilities
- Add createTestQueryClient helper with retry: false for faster test execution
## Test Coverage
- Test files: 15 → 17 (+2)
- Total tests: 105 → 112 (+6.7%)
- All 112 tests passing
- Execution time: 3.15s
SettingsDialog Integration Tests:
- Add test for directory browsing and reset functionality
- Verify app config directory browse/reset flow
- Verify Claude config directory manual change, browse, and reset
- Test multiple directory inputs with getAllByTitle pattern
- Add test for export failure error handling
- User cancels file selection (save_file_dialog returns null)
- Export operation fails (disk full scenario)
- Use server.use() to dynamically override MSW handlers
- Verify toast error messages match i18n keys
MSW Handler Extension:
- Add pick_directory handler to support directory selection API
- Consistent with select_config_directory mock strategy
useSettings Hook Unit Tests:
- Add comprehensive tests for settings save logic
- Test restart flag when app config directory changes
- Test no restart when directory unchanged
- Verify space trimming and empty string to undefined conversion
- Test Claude plugin sync failure tolerance
- Add test for settings reset functionality
- Verify form/language/directories reset with server data
- Use factory functions for mock creation (reusability)
- Complete dependency isolation with mock hooks
All tests passing: 9/9 (5 integration + 4 unit tests)
Major testing infrastructure upgrade from manual mocks to Mock Service Worker (MSW):
New MSW infrastructure (tests/msw/):
- Add state.ts: In-memory state manager with full CRUD operations
- Manage providers and current selections per app type (Claude/Codex)
- Auto-switch current provider when deleted
- Deep clone to prevent reference pollution
- Add handlers.ts: HTTP request handlers for 10 Tauri API endpoints
- Mock get_providers, switch_provider, add/update/delete_provider
- Mock update_sort_order, update_tray_menu, import_default_config
- Support error scenarios (404 for non-existent providers)
- Add tauriMocks.ts: Tauri API mock layer
- Transparently convert invoke() calls to HTTP requests
- Mock event listener system with emitTauriEvent helper
- Use cross-fetch for Node.js environment
- Add server.ts: MSW server setup for Node.js test environment
Refactor App.test.tsx (-170 lines, -43%):
- Remove 23 manual mocks (useProvidersQuery, useProviderActions, etc.)
- Run real hooks with MSW-backed API calls instead of mock implementations
- Test real state changes instead of mock call counts
- Add comprehensive flow: duplicate → create → edit → delete → event listening
- Verify actual provider list changes and current selection updates
Setup integration:
- Add MSW server lifecycle to tests/setupTests.ts
- Start server before all tests
- Reset handlers and state after each test
- Close server after all tests complete
- Clear all mocks in afterEach for test isolation
Dependencies:
- Add msw@^2.11.6 for API mocking
- Add cross-fetch@^4.1.0 for fetch polyfill in Node.js
Type fixes:
- Add missing imports (AppType, Provider) in handlers.ts
- Fix HttpResponse.json generic constraint with as any (MSW best practice)
- Change invalid category "default" to "official" in state.ts
Test results: All 50 tests passing across 8 files, 0 TypeScript errors
