Testing Overview

​

Testing Strategy

• Python Service: pytest-based test suite with fixtures and database isolation
• Node.js Service: Jest-based test suite with Sequelize ORM integration
• Integration Testing: Full API endpoint coverage with authenticated requests
• Security Testing: SQL injection prevention and input validation tests
