## Features

### Workflow Triggers

All workflows support multiple triggers:

1. **Push Events**
   - Automatic run on push to `main` or `develop`
   - Path filtering to run only when relevant files change

2. **Pull Request Events**
   - Run on all PRs to `main` or `develop`
   - Provide feedback before merge

3. **Scheduled Runs**
   - Security scan: Daily at 2 AM UTC
   - Performance benchmarks: Weekly (Sunday 3 AM UTC)

4. **Manual Dispatch**
   - On-demand execution from Actions tab
   - Optional parameter input (e.g., test type)

### Quality Gates

#### Test Coverage
- **Minimum**: 80% (enforced by pytest)
- **Target**: 95%+
- **Tools**: pytest-cov, Codecov integration

#### Code Quality
- **Linter**: Ruff (replaces black/flake8/isort)
- **Formatter**: Ruff format
- **Type Checking**: mypy (strict mode)
- **Complexity**: max 15 (Complexipy)

#### Security
- **Dependency Scanning**: Safety (daily)
- **Code Security**: Bandit
- **Secret Detection**: TruffleHog
- **Zero tolerance**: All security issues must be fixed

### Matrix Strategies

#### Test Matrix
```yaml
matrix:
  adapter: [core, prefect, agno, langgraph, llamaindex]
  python-version: ['3.11', '3.12', '3.13']
```
Total: 15 unit test jobs

#### Integration Test Matrix
```yaml
matrix:
  suite: [adapters, mcp-server, pool-management, phase3-advanced]
```
Total: 4 integration test jobs

#### Example Validation Matrix
```yaml
matrix:
  category: [quickstart, workflows, integrations, phase3-advanced]
```
Total: 4 example validation jobs

### Caching

Workflows use multiple caching strategies:

1. **pip Cache**
```yaml
- uses: actions/setup-python@v5
  with:
    cache: 'pip'
```

2. **uv Cache** (faster dependency manager)
```yaml
- name: Cache uv
  uses: actions/cache@v4
  with:
    path: ~/.cache/uv
    key: ${{ runner.os }}-uv-${{ hashFiles('pyproject.toml') }}
```

### Artifacts

Workflows generate artifacts with varying retention periods:

| Artifact | Retention | Description |
|----------|-----------|-------------|
| Coverage reports | 7 days | HTML and XML coverage reports |
| Benchmark results | 30 days | JSON benchmark data |
| Security reports | 30 days | Safety, Bandit, TruffleHog reports |
| Code quality reports | 7 days | Ruff, mypy reports |
| Test reports | 7 days | pytest and E2E test reports |
| Documentation | 7 days | Built documentation files |

## Usage Examples

### Running Tests Locally

```bash
# Unit tests
pytest tests/unit/ -m "unit" --cov=mahavishnu

# Integration tests
pytest tests/integration/ -m "integration"

# E2E tests
pytest tests/integration/ -m "e2e" --timeout=600

# Specific adapter tests
pytest tests/unit/test_adapters/test_prefect*.py -v

# Parallel execution
pytest -n auto
```

### Security Scanning Locally

```bash
# Dependency vulnerabilities
safety check

# Code security
bandit -r mahavishnu/ --exclude tests/

# Linting
ruff check mahavishnu/

# Formatting
ruff format --check mahavishnu/

# Type checking
mypy mahavishnu/

# Complexity
complexipy --max_complexity 15 mahavishnu/
```

### Performance Testing Locally

```bash
# Benchmarks
pytest tests/unit/test_adapters/ -k "benchmark" --benchmark-only

# Load test
python -c "
import asyncio
import time
from mahavishnu.core.app import MahavishnuApp

async def load_test():
    app = MahavishnuApp()
    await app.initialize()

    start = time.time()
    tasks = [app.list_repos() for _ in range(100)]
    await asyncio.gather(*tasks)
    duration = time.time() - start

    print(f'100 concurrent operations: {duration:.2f}s')
    print(f'Operations per second: {100/duration:.2f}')

asyncio.run(load_test())
"

# Memory profiling
pip install memory-profiler
python -m memory_profiler examples/quickstart/*.py
```

## Best Practices

### 1. Test-Driven Development

```python
import pytest

@pytest.mark.unit
def test_adapter_initialization():
    """Unit test for adapter initialization."""
    adapter = PrefectAdapter(config={})
    assert adapter.is_initialized()
    assert adapter.config['max_workers'] > 0

@pytest.mark.integration
@pytest.mark.prefect
def test_prefect_workflow_execution():
    """Integration test for Prefect workflow."""
    adapter = PrefectAdapter(config={})
    result = adapter.run_workflow("test_flow")
    assert result.status == "success"
```

### 2. Security-Aware Development

```python
# Good: Use environment variables for secrets
import os
api_key = os.getenv('API_KEY')

# Bad: Hardcoded secrets
api_key = "sk-1234567890abcdef"

# Good: Input validation
from pydantic import BaseModel, validator

class UserInput(BaseModel):
    name: str

    @validator('name')
    def validate_name(cls, v):
        if not v or len(v) > 100:
            raise ValueError('Invalid name')
        return v

# Bad: Unvalidated input
def process(name):
    return name.upper()
```

### 3. Performance-Aware Development

```python
# Good: Async operations
import asyncio

async def fetch_multiple(items):
    tasks = [fetch_item(item) for item in items]
    return await asyncio.gather(*tasks)

# Bad: Sequential operations
def fetch_multiple(items):
    return [fetch_item(item) for item in items]

# Good: Connection pooling
from aiohttp import ClientSession

async def fetch_with_pool(urls):
    async with ClientSession() as session:
        tasks = [fetch_url(session, url) for url in urls]
        return await asyncio.gather(*tasks)

# Bad: New connection per request
async def fetch_without_pool(urls):
    return [await fetch_url(url) for url in urls]
```

## Troubleshooting

### Common Issues

**Issue: Tests fail in CI but pass locally**

Solution:
```bash
# Ensure same Python version
python --version  # Should be 3.13

# Run with same pytest configuration
pytest tests/unit/ -m "unit" --cov=mahavishnu --cov-report=xml

# Check for environment-specific issues
pytest tests/unit/ -m "unit" --tb=long -vv
```

**Issue: Security scan failures**

Solution:
```bash
# Run locally to see full report
bandit -r mahavishnu/ --exclude tests/

# Fix specific issues
ruff check mahavishnu/ --fix

# Update dependencies
safety check --fix
```

**Issue: Performance regression detected**

Solution:
```bash
# Run benchmarks locally
pytest tests/unit/test_adapters/ -k "benchmark" --benchmark-only

# Compare with previous run
pytest tests/unit/test_adapters/ -k "benchmark" --benchmark-only --benchmark-autosave

# Profile slow code
python -m cProfile -o profile.stats your_script.py
python -m pstats profile.stats
```
