pytest-fixture-generator

# Pytest Fixture Generator

## Quick Start

```bash
# Generate pytest configuration
/pytest-fixture-generator

# Generate with specific markers
/pytest-fixture-generator --markers unit,integration,slow

# Generate for specific module structure
/pytest-fixture-generator --src-path src/modules
```

## When to Use

**USE when:**
- Setting up new Python project testing
- Standardizing existing test configuration
- Adding fixtures for data processing projects
- Configuring coverage requirements

**DON'T USE when:**
- Non-Python projects
- Tests already fully configured
- Different testing framework needed

## Prerequisites

- Python 3.9+
- pytest>=7.4.0
- pytest-cov>=4.1.0
- Project with src/ structure

## Overview

Generates complete pytest configuration including:

1. **pytest.ini** - pytest configuration with markers
2. **conftest.py** - Shared fixtures and path setup
3. **Coverage config** - .coveragerc or pyproject.toml
4. **Test templates** - Example test files

## Generated Files

### pytest.ini

```ini
[pytest]
testpaths = tests
python_files = test_*.py *_test.py
python_classes = Test*
python_functions = test_*

# Markers for test categorization
markers =
    unit: Unit tests (fast, isolated)

*See sub-skills for full details.*
### conftest.py

```python
"""
ABOUTME: Pytest configuration and shared fixtures for testing
ABOUTME: Provides path setup, common fixtures, and test utilities
"""

import sys
from pathlib import Path
from typing import Any, Dict, Generator
import pytest
