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.
Mock Refactoring:
- Extract saveFileDialogMock and exportConfigMock as variables
- Previously used inline vi.fn() which prevented call verification
- Now supports expect().toHaveBeenCalledWith() assertions
- Enables parameter and return value validation
- Add mock reset in beforeEach for test isolation
- Reset saveFileDialogMock state
- Reset exportConfigMock state
- Ensures clean state for each test
New Test: Import Failure Callback Verification
- Add test "does not call onImportSuccess when import fails"
- User selects file successfully
- Import operation fails (success: false)
- Verify onImportSuccess callback NOT called
- Verify status becomes "error"
- Prevents triggering success logic on failure
New Test: Export Success Message Verification
- Add test "propagates export success message to toast with saved path"
- User selects save location: /exports/config.json
- Backend saves to: /final/config.json (may differ)
- Verify exportConfigMock called with user-selected path
- Verify toast success message contains actual saved path
- Ensures user sees correct save location
Coverage Improvements:
- Import failure callback: 50% → 100%
- Export success message: 50% → 100%
- Mock verification capability: 0% → 100%
All tests passing: 81/81 (2 new tests)
useSettings Tests:
- Add test for null settings state protection
- Returns null immediately without calling APIs
- Prevents null pointer errors in save flow
- Add test for save mutation failure
- Verifies error propagates to caller
- Ensures restart flag remains untouched on failure
- Validates no side effects when save fails
useProviderActions Tests:
- Add error propagation tests for CRUD operations
- updateProvider: propagates errors to caller
- addProvider: propagates errors to caller
- deleteProvider: propagates errors to caller
- Add switch mutation error handling tests
- Claude switch: handles errors silently (no throw)
- Codex switch: skips plugin sync when mutation fails
- Verifies plugin sync APIs not called on failure
- Add loading state verification
- Test all mutations pending scenario (existing)
- Test all mutations idle scenario (new)
- Ensures isLoading flag accuracy
useImportExport Edge Case Tests (new file):
- Add test for user cancelling file dialog
- File dialog returns null (user cancelled)
- State remains unchanged (selectedFile: "", status: "idle")
- No error toast shown
- Add test for resetStatus behavior
- Clears error message and status
- Preserves selected file path for retry
- Resets backupId to null
All tests passing: 79/79 (10 new tests)
