# netrun-pytest-fixtures

Unified pytest fixtures for Netrun Systems services. Eliminates 71% fixture duplication across Service_* test suites.

## Features

- **Async Utilities**: Session-scoped event loops for async testing (addresses 71% duplication)
- **Authentication**: RSA key pairs, JWT claims, test users with role hierarchies
- **Database**: SQLAlchemy async sessions with automatic cleanup
- **API Clients**: httpx AsyncClient and FastAPI TestClient mocks
- **Redis**: Mock Redis clients with full operation support
- **Environment**: Environment variable isolation and management
- **Filesystem**: Temporary files, directories, and repository structures
- **Logging**: Logging reset and capture utilities

## Installation

```bash
pip install netrun-pytest-fixtures
```

### Optional Dependencies

Install with specific fixture modules:

```bash
# SQLAlchemy fixtures
pip install netrun-pytest-fixtures[sqlalchemy]

# HTTP client fixtures
pip install netrun-pytest-fixtures[httpx]

# FastAPI fixtures
pip install netrun-pytest-fixtures[fastapi]

# Redis fixtures
pip install netrun-pytest-fixtures[redis]

# YAML file fixtures
pip install netrun-pytest-fixtures[yaml]

# All optional dependencies
pip install netrun-pytest-fixtures[all]
```

## Usage

Simply install the package - fixtures are automatically registered as a pytest plugin.

```python
# test_example.py
import pytest


# Async testing with event loop fixture
@pytest.mark.asyncio
async def test_async_operation(event_loop):
    async def my_async_function():
        return "result"

    result = await my_async_function()
    assert result == "result"


# Authentication testing
def test_jwt_claims(sample_jwt_claims, rsa_key_pair):
    private_pem, public_pem = rsa_key_pair

    assert "sub" in sample_jwt_claims
    assert "tenant_id" in sample_jwt_claims
    assert len(private_pem) > 0


# Database testing
@pytest.mark.asyncio
async def test_database(async_db_session):
    # Use async database session
    # Changes automatically rolled back after test
    pass


# Redis testing
@pytest.mark.asyncio
async def test_redis_cache(mock_redis):
    await mock_redis.set("key", "value")
    mock_redis.set.assert_called_once_with("key", "value")


# Environment testing
def test_config(clean_env, sample_env_vars):
    for key, value in sample_env_vars.items():
        clean_env.setenv(key, value)

    # Test configuration loading
    pass


# Filesystem testing
def test_file_operations(temp_directory):
    test_file = temp_directory / "test.txt"
    test_file.write_text("content")
    assert test_file.exists()
```

@pytest.mark.asyncio
async def test_user_creation(async_db_session):
    """Test creating a user in the database."""
    user = User(name="Test User", email="test@netrunsystems.com")
    async_db_session.add(user)
    await async_db_session.commit()

    # Query the user
    result = await async_db_session.execute(

    )
    found_user = result.scalar_one()

    assert found_user.name == "Test User"
    # Changes automatically rolled back after test
```

def test_jwt_encoding_decoding(rsa_key_pair, sample_jwt_claims):
    """Test JWT encoding and decoding with RSA keys."""
    private_pem, public_pem = rsa_key_pair

    # Encode JWT
    token = jwt.encode(
        sample_jwt_claims,
        private_pem,
        algorithm="RS256"
    )

    # Decode JWT
    decoded = jwt.decode(
        token,
        public_pem,
        algorithms=["RS256"]
    )

    assert decoded["sub"] == sample_jwt_claims["sub"]
    assert decoded["tenant_id"] == sample_jwt_claims["tenant_id"]
```

    app = FastAPI()

    @app.get("/users")
    async def get_users():
        return [{"id": "1", "name": "Test User"}]

    return app


def test_get_users_endpoint(test_client, app):
    """Test GET /users endpoint."""
    client = test_client(app)
    response = client.get("/users")

    assert response.status_code == 200
    data = response.json()
    assert len(data) == 1
    assert data[0]["name"] == "Test User"
```

#### Testing Redis Caching

```python
import pytest


@pytest.mark.asyncio
async def test_cache_user_data(mock_redis_with_data):
    """Test caching user data in Redis."""
    # Cache user data
    user_data = '{"id": "123", "name": "Test User"}'
    await mock_redis_with_data.set("user:123", user_data)

    # Retrieve from cache
    cached = await mock_redis_with_data.get("user:123")
    assert cached == user_data


@pytest.mark.asyncio
async def test_cache_miss_handling(mock_redis):
    """Test handling cache misses."""
    mock_redis.get.return_value = None

    result = await mock_redis.get("nonexistent:key")
    assert result is None
```

#### Testing Environment Configuration

```python
import pytest
import os


def test_load_config_from_env(clean_env, sample_env_vars):
    """Test loading configuration from environment."""
    # Set environment variables
    for key, value in sample_env_vars.items():
        clean_env.setenv(key, value)

    # Load config
    assert os.getenv("APP_NAME") == "TestApp"
    assert os.getenv("APP_ENVIRONMENT") == "testing"


def test_config_from_env_file(mock_env_file):
    """Test loading configuration from .env file."""
    from dotenv import load_dotenv

    load_dotenv(mock_env_file)

    assert os.getenv("APP_NAME") == "EnvFileApp"
    assert os.getenv("LOG_LEVEL") == "WARNING"
```
