## What's Still Missing

### Medium Priority
1. **InputBar component tests** - Input validation, file attachments, context pills
2. **Core agent library tests** - MastraAgent, ToolRegistry, ModelFallback
3. **IPC handler tests** - Electron IPC communication
4. **Tool execution tests** - Bash, filesystem tools

### Low Priority
5. Sidebar component tests
6. Settings component tests
7. Tab component tests
8. Artifacts component tests

## Test Architecture Highlights

### 1. Separation of Concerns
- **Unit tests** (`test/unit/`): Fast, isolated
- **Integration tests** (`test/integration/`): Cross-service interactions
- **E2E tests** (`test/e2e/`): Full user workflows
- **UI tests** (`ui/__tests__/`): React components

### 2. OpenClaw-Inspired Structure
Following the proven architecture from OpenClaw (179k ⭐):
- Multiple vitest configs for different test types
- Proper test isolation
- Comprehensive coverage tracking
- Fast feedback loops

### 3. Real-World Testing
- Tests use actual services (with mocks where appropriate)
- WebSocket tests create real connections
- Storage tests use real SQLite databases (temp directories)
- E2E tests launch actual Electron app

### 4. Fail-Safe Design
- Tests gracefully handle missing API keys
- Cleanup happens even on test failure
- Timeouts set appropriately for each test type
- Parallel tests don't interfere with each other
