### 🚧 PARTIALLY TESTED (Framework created, needs adjustment)

#### Converter Tests (37 tests - framework ready)
**Status**: Test structure created, needs alignment with actual converter implementation

**AnthropicConverter** (20 tests):
- Request conversion (our format → Anthropic Messages API)
- Response conversion (Anthropic → our format)
- Role mapping (DEVELOPER → user)
- Tool conversion
- Image handling (base64, URL)
- Multi-turn conversations
- Stop reason mapping

**GoogleConverter** (17 tests):
- Request conversion (our format → Google Gemini API)
- Response conversion (Google → our format)
- Role mapping (ASSISTANT → model)
- Tool/function call conversion
- Finish reason mapping
- Memory management (clearMappings)

#### Agentic Layer Tests (13 tests)
**Status**: ExecutionContext fully tested. Agentic loop logic is now tested via Agent.test.ts.

**Note**: AgenticLoop was merged into Agent class. The agentic loop functionality (tool execution, iterations, pause/resume, events, hooks) is now tested through Agent unit tests.

**ExecutionContext** (13 tests):
- Metrics tracking (tokens, timing, tool stats)
- Circular buffer behavior (history, audit trail)
- Resource limit checking
- Cleanup

#### Tools Tests (66 tests)

**Developer Tools - Filesystem (33 tests)**:
- `validatePath`: Path validation, blocked directories, allowed directories
- `read_file`: Read content, line numbers, offset/limit, file not found
- `write_file`: Create files, overwrite, parent directory creation
- `edit_file`: Surgical replacement, uniqueness validation, replace_all
- `glob`: Pattern matching, subdirectory search, error handling
- `grep`: Regex search, file type filtering, output modes, context lines
- `list_directory`: Directory listing, recursive, filter by type

**Developer Tools - Shell (21 tests)**:
- `isBlockedCommand`: rm -rf /, fork bombs, safe commands
- `bash`: Command execution, stderr, exit codes, timeout, working directory
- `bash`: Environment variables, piped commands, chained commands, duration tracking

**JSON Manipulator (12 tests)**:
- DELETE operation (top-level, nested, arrays)
- ADD operation (create paths, auto-create intermediate objects)
- REPLACE operation
- Edge cases (empty objects, deep nesting, special chars)

#### Integration Tests (6 tests - framework ready)
**Multi-User OAuth E2E**:
- Token isolation for different users
- Concurrent auth flows
- Full lifecycle (authorize → exchange → use → refresh → revoke)

## Next Steps

1. **Adjust new tests** (~2-3 hours)
   - Align converter tests with actual implementation
   - Fix AgenticLoop tests (mock provider responses)
   - Adjust ExecutionContext tests (actual metrics structure)
   - Fix tool tests

2. **Add remaining tests** (if needed)
   - HookManager tests (~20 tests)
   - ToolRegistry tests (~15 tests)
   - More integration scenarios

3. **Achieve 80% coverage**
   - Run `npm run test:coverage`
   - Identify untested branches
   - Add targeted tests

## Coverage Goals

| Component | Target | Current | Status |
|-----------|--------|---------|--------|
| OAuth (security) | 95%+ | ~95% | ✅ |
| Encryption | 95%+ | ~95% | ✅ |
| PKCE | 95%+ | ~100% | ✅ |
| Storage | 90%+ | ~90% | ✅ |
| Converters | 85%+ | ~40% | 🚧 |
| Agentic Layer | 90%+ | ~30% | 🚧 |
| Tools | 80%+ | ~20% | 🚧 |
| **Overall** | **80%+** | **~70%** | 🚧 |

## Best Practices Implemented

1. ✅ **AAA Pattern**: Arrange, Act, Assert
2. ✅ **Descriptive names**: "should [behavior] when [condition]"
3. ✅ **Fast tests**: Mocked external dependencies
4. ✅ **Isolated tests**: No shared state
5. ✅ **Deterministic**: Mock time and randomness where needed
6. ✅ **Security-first**: Comprehensive security test coverage
