- ✅ Handle invalid response
- ✅ Handle missing key in keys map

**Real-World Scenarios:**

- ✅ curl with multiple headers
- ✅ Python script with env vars
- ✅ Git commands with credentials

**Edge Cases:**
- ✅ Empty command
- ✅ Command with no keys (callback not called)

**Basic Generation:**
- ✅ Generate complete prompt
- ✅ Include identity section
- ✅ Include tool call style guidelines

**API Key Documentation:**
- ✅ Include API keys section
- ✅ Document ${KEY_NAME} syntax
- ✅ Explain permission system (ask vs always)

- ✅ Include custom keys when provided

**Tool Documentation:**
- ✅ Include bash tool documentation
- ✅ Include filesystem tools (read, write, list, search)
- ✅ Include tool examples
- ✅ List available tools

**Security Guidelines:**
- ✅ Include security section
- ✅ Warn about key sanitization (***)
- ✅ Mention permission denials

**Behavior Guidelines:**

- ✅ Include narration guidelines

**Options & Customization:**
- ✅ Accept workspace path
- ✅ Accept user data path
- ✅ Work with minimal options
- ✅ Work with all options

**Content Structure:**
- ✅ Proper markdown structure (#, ##)
- ✅ Code blocks (```bash)
- ✅ Consistent formatting

**Real-World Examples:**
- ✅ curl with API key
- ✅ Multiple key usage examples

**Edge Cases:**
- ✅ Empty custom keys array
- ✅ Undefined options
- ✅ Special characters in key names

**Consistency:**
- ✅ Same prompt for same options
- ✅ Deterministic generation

---

### 5. ✅ `bash-tool.test.ts` (Existing - Needs Update)
**Coverage:** Bash tool execution  
**Current:** Basic execution tests  
**Needs:** Permission flow integration tests

**Suggested New Tests:**
```typescript
// Test permission request flow
test('should request permission for ${KEY} in command')
test('should not execute if permission denied')
test('should substitute key after approval')

// Test permission caching
test('should not request again for always-allowed keys')
```

---

### 6. 📝 Integration Tests (TODO)
**File:** `tests/permissions-integration.test.ts`  
**Coverage:** End-to-end permission flow

**What Should Be Tested:**
- [ ] Gateway → Main → Renderer IPC flow
- [ ] Modal appears on permission request
- [ ] User approves and key is substituted
- [ ] User denies and error is returned
- [ ] "Always allow" persists across sessions
- [ ] Multiple sequential permission requests
- [ ] Permission timeout handling (30s)
- [ ] Concurrent permission requests

**Note:** These require mocking Electron IPC or E2E testing with Playwright.

## Test Execution

### Run All Permission Tests
```bash
npm test -- permissions
```

### Run Specific Test Files
```bash
# Security features (Phase 1)
npm test -- security-features

# Storage layer
npm test -- permissions-storage

# Permission-aware substitution
npm test -- permission-substitution

# System prompt
npm test -- system-prompt
```

### Run All Tests
```bash
npm test
```

## What's NOT Tested (Requires E2E)

### Electron IPC Flow
- ❌ Main process IPC handlers (`src/electron/ipc/permissions.ts`)
- ❌ Preload API exposure (`src/electron/preload.cjs`)
- ❌ Gateway-to-Main process IPC (`GatewayPermissionBridge`)

### UI Components
- ❌ `KeyPermissionModal` rendering
- ❌ `useKeyPermissions` hook
- ❌ Modal user interactions (click Allow/Deny)

### Integration
- ❌ Full bash tool + permission flow
- ❌ Permission persistence across app restarts
- ❌ Settings UI for managing permissions

**Solution:** These require Playwright E2E tests or manual testing.

## Quick Test Commands

```bash
# Run all unit tests
npm test

# Run only permission tests
npm test -- permissions

# Run with coverage
npm test -- --coverage

# Watch mode for development
npm test -- --watch

# Run specific test
npm test -- permissions-storage
```

## Test Checklist

**Unit Tests:** ✅ Complete (110+ test cases)
- ✅ Security utilities
- ✅ Permission storage
- ✅ Permission-aware substitution
- ✅ System prompt builder

**Integration Tests:** ⚠️ Manual testing required
- ⏳ Electron IPC flow (manual)
- ⏳ UI components (manual)
- ⏳ End-to-end flow (manual)

**E2E Tests:** 📋 Planned
- ⏳ Playwright tests for full permission flow
- ⏳ Cross-process IPC testing
- ⏳ UI interaction testing

---

## Testing Next Steps

1. **Run unit tests** to verify all pass:
   ```bash
   npm test
   ```

2. **Manual testing** in UI (7 test scenarios in `TESTING_CHECKLIST.md`)

3. **Create E2E tests** (future):
   - Set up Playwright for Electron
   - Test permission modal interactions
   - Test IPC communication
   - Test persistence across restarts

---

**Summary:** 110+ unit tests covering all core functionality. Manual testing required for Electron-specific features and UI interactions.
