## McpFormModal Component Tests (+5 tests)
### Infrastructure Improvements
- Enhance McpWizardModal mock from null to functional mock with testable onApply callback
- Refactor renderForm helper to support custom onSave/onClose mock injection
- Add McpServer type import for type-safe test data
### New Test Cases
1. **Wizard Integration**: Verify wizard generates config and auto-fills ID + JSON fields
- Click "Use Wizard" → Apply → Form fields populated with wizard-id and config
- Uses act() wrapper for React 18 async state updates
2. **TOML Auto-extraction (Codex)**: Test TOML → JSON conversion with ID extraction
- Parse `[mcp.servers.demo]` → auto-fill ID as "demo"
- Verify server object correctly parsed from TOML format
- Codex-specific feature for config.toml compatibility
3. **TOML Validation Error**: Test missing required field handling
- TOML with type="stdio" but no command → block submit
- Display localized error toast: mcp.error.idRequired (3s duration)
4. **Edit Mode Immutability**: Verify ID field disabled during edit
- ID input has disabled attribute and keeps original value
- Config updates applied while enabled state preserved
- syncOtherSide defaults to false in edit mode
5. **Error Recovery**: Test save failure button state restoration
- Inject failing onSave mock → trigger error
- Verify toast error displays translated message
- Submit button disabled state resets to false for retry
## useMcpActions Hook Tests (+2 tests)
### New API Mocks
- Add syncEnabledToClaude and syncEnabledToCodex mock functions
### New Test Cases
1. **Backend Error Message Mapping**: Map Chinese error to i18n key
- Backend: "stdio 类型的 MCP 服务器必须包含 command 字段"
- Frontend: mcp.error.commandRequired (6s toast duration)
2. **Cross-app Sync Logic**: Verify conditional sync behavior
- claude → claude: setEnabled called, syncEnabledToClaude NOT called
- Validates sync only occurs when crossing app types
## Minor Changes
- McpPanel.test.tsx: Add trailing newline (formatter compliance)
## Test Coverage
- Test files: 17 (unchanged)
- Total tests: 112 → 119 (+7, +6.3%)
- Execution time: 3.20s
- All 119 tests passing ✅
