**Framework:** pytest 7.4+ with Python 3.12+  
**Architect:** Murat (TEA - Master Test Architect)

## Summary

✅ **Production-ready pytest framework setup complete for TraceRTM**

---

## Artifacts Created

### 1. Project Configuration (`pyproject.toml`)
**Purpose**: Python project configuration with test dependencies

**Key Sections**:
- **Dependencies**: typer, rich, sqlalchemy, pydantic, psycopg2
- **Dev Dependencies**: pytest, pytest-cov, pytest-asyncio, faker, factory-boy, ruff, mypy
- **pytest Configuration**: Test paths, markers, coverage settings
- **Coverage Configuration**: 80%+ target, branch coverage, HTML reports
- **Ruff Configuration**: Linting rules (line-length 120, Python 3.12)
- **mypy Configuration**: Strict type checking

**Test Markers**:
- `@pytest.mark.unit` - Fast unit tests (<100ms)
- `@pytest.mark.integration` - Integration tests with database
- `@pytest.mark.e2e` - End-to-end CLI workflows
- `@pytest.mark.slow` - Slow tests (>1s)
- `@pytest.mark.agent` - Agent coordination tests

### 2. Test Configuration (`tests/conftest.py`)
**Purpose**: Shared fixtures and pytest configuration

**Fixtures Provided**:
- `test_db_engine` - Session-scoped database engine
- `db_session` - Function-scoped database session (auto-rollback)
- `temp_project_dir` - Temporary directory for file operations
- `test_config` - Test configuration dictionary
- `cli_runner` - Typer CLI test runner
- `mock_agent_pool` - Mock agent pool for concurrency testing

**Auto-Marking**:
- Tests in `tests/unit/` automatically marked with `@pytest.mark.unit`
- Tests in `tests/integration/` automatically marked with `@pytest.mark.integration`
- Tests in `tests/e2e/` automatically marked with `@pytest.mark.e2e`

### 3. Test Directory Structure
```

└── e2e/                        # End-to-end tests (CLI workflows)
    └── __init__.py
```

### 4. Test Data Factories
**Purpose**: Generate realistic test data with faker

**ItemFactory** (`tests/factories/item_factory.py`):
- `create()` - Create single item with faker data
- `create_batch(count)` - Create multiple items
- `create_hierarchy(depth, children_per_level)` - Create hierarchical structure
- `cleanup()` - Auto-cleanup after tests

**ProjectFactory** (`tests/factories/project_factory.py`):
- `create()` - Create test project
- `cleanup()` - Auto-cleanup

**LinkFactory** (`tests/factories/link_factory.py`):
- `create(source, target, link_type)` - Create test link
- `cleanup()` - Auto-cleanup

### 5. Test Documentation (`tests/README.md`)
**Purpose**: Comprehensive test suite documentation

**Contents**:
- Quick start commands
- Test directory structure
- Test categories (unit, integration, e2e, agent)
- Test fixtures documentation
- Writing tests guide (AAA pattern, naming conventions)
- Running tests in CI
- Test data management
- Troubleshooting guide

## Test Strategy

### Unit Tests (`tests/unit/`)
- **Speed**: <100ms per test
- **Dependencies**: None (mocked)
- **Coverage Target**: 90%+
- **Purpose**: Test individual functions/classes in isolation

### Integration Tests (`tests/integration/`)
- **Speed**: <1s per test
- **Dependencies**: PostgreSQL test database
- **Coverage Target**: 80%+
- **Purpose**: Test component interactions

### E2E Tests (`tests/e2e/`)
- **Speed**: <5s per test
- **Dependencies**: Full system (database, CLI)
- **Coverage Target**: 100% of critical workflows
- **Purpose**: Test complete user workflows via CLI

### Agent Tests (`tests/integration/`)
- **Speed**: <10s per test
- **Dependencies**: PostgreSQL, agent pool
- **Coverage Target**: 100% of concurrency scenarios
- **Purpose**: Test concurrent agent operations (1-1000 agents)

## Running Tests

```bash
# Install dev dependencies
pip install -e ".[dev]"

# Run all tests
pytest

# Run with coverage
pytest --cov=tracertm --cov-report=html

# Run specific test categories
pytest -m unit          # Fast unit tests only
pytest -m integration   # Integration tests
pytest -m e2e           # End-to-end tests
pytest -m agent         # Agent coordination tests

# Run tests in parallel
pytest -n auto

# Run specific test file
pytest tests/unit/test_item_repository.py
```

---

## Coverage Configuration

**Target**: 80%+ overall, 90%+ for business logic

**Reports**:
- Terminal: `--cov-report=term-missing`
- HTML: `--cov-report=html` (opens in `htmlcov/index.html`)
- XML: `--cov-report=xml` (for CI/CD)

**Excluded**:
- `*/tests/*`
- `*/migrations/*`
- `*/__pycache__/*`

---

## Next Steps

1. ✅ Test framework setup complete
2. → **Run `*test-design` for Epic 1** to create test-design-epic-1.md
3. → Write unit tests for Epic 1 stories
4. → Implement Epic 1 with TDD approach
5. → Run `*trace` to verify FR → Story → Test Case traceability

## Knowledge Base References

**TEA Knowledge Fragments Applied**:
- Fixture architecture pattern (pure functions + auto-cleanup)
- Data factories with faker (realistic test data)
- Test isolation (transaction rollback per test)
- Test categorization (markers for unit/integration/e2e)
- Coverage configuration (branch coverage, HTML reports)

**Framework Setup Complete**: 2025-11-21  
**Ready for**: `*test-design` workflow (Epic 1)  
**Status**: ✅ **READY FOR TEST DESIGN**
