+
+## Purpose
+
+This command helps you run Python tests effectively with proper configuration and reporting.
+
+## Usage
+
+```
+/test
+```
+
+## What this command does
+
+1. **Detects test framework** (pytest, unittest, nose2)
+2. **Runs appropriate tests** with proper configuration
+3. **Provides coverage reporting** if available
+4. **Shows clear test results** with failure details
+
+## Example Commands
+
+### pytest (recommended)
+```bash
+# Run all tests
+pytest
+
+# Run with coverage
+pytest --cov=src --cov-report=html
+
+# Run specific test file
+pytest tests/test_models.py
+
+# Run with verbose output
+pytest -v
+
+# Run tests matching pattern
+pytest -k "test_user"
+```
+
+### unittest
+```bash
+# Run all tests
+python -m unittest discover
+
+# Run specific test file
+python -m unittest tests.test_models
+
+# Run with verbose output
+python -m unittest -v
+```
+
+### Django tests
+```bash
+# Run all Django tests
+python manage.py test
+
+# Run specific app tests
+python manage.py test myapp
+
+# Run with coverage
+coverage run --source='.' manage.py test
+coverage report
+```
+
+## Best Practices
+
+- Write tests for all critical functionality
+- Use descriptive test names
+- Keep tests isolated and independent
+- Mock external dependencies
+- Aim for high test coverage (80%+)
