🧪 Testing Framework

Content Outline

Comprehensive guide to PyMapGIS testing philosophy, tools, and practices:

1. Testing Philosophy

• Test-driven development approach
• Testing pyramid (unit, integration, end-to-end)
• Quality assurance standards
• Continuous testing practices

2. Test Categories

• Unit Tests: Individual function and class testing
• Integration Tests: Module interaction testing
• End-to-End Tests: Complete workflow testing
• Performance Tests: Benchmarking and optimization
• Regression Tests: Preventing feature breakage

3. Testing Tools and Framework

• pytest configuration and usage
• Test fixtures and data management
• Mocking and stubbing strategies
• Coverage measurement and reporting
• Parallel test execution

4. Test Data Management

• Sample data creation and management
• Mock data source implementations
• Test data versioning and updates
• Large dataset testing strategies
• Geospatial test data best practices

5. Geospatial Testing Specifics

• Geometry comparison and validation
• Coordinate system testing
• Spatial operation verification
• Raster data testing approaches
• Visualization testing strategies

6. Performance Testing

• Benchmarking methodologies
• Performance regression detection
• Memory usage testing
• I/O performance measurement
• Scalability testing approaches

7. CI/CD Integration

• GitHub Actions configuration
• Automated test execution
• Test result reporting
• Coverage tracking
• Performance monitoring

8. Test Writing Guidelines

• Test naming conventions
• Test structure and organization
• Assertion best practices
• Error condition testing
• Documentation and comments

9. Debugging and Troubleshooting

• Test failure analysis
• Debugging techniques
• Test environment issues
• Flaky test management
• Performance bottleneck identification

10. Advanced Testing Topics

• Property-based testing
• Mutation testing
• Security testing
• Compatibility testing
• Load and stress testing
