This tool generates comprehensive end-to-end tests that validate entire user journeys from UI interactions through backend services. E2E tests are essential for full application flow testing, integration of frontend and backend validation, and ensuring critical business workflows function correctly across all layers.

The tool requires both a Playwright frontend trace and a backend trace file to capture the complete application behavior. It supports authorization headers for backend API calls and can enable code reuse and modularization for better test organization. The tool intelligently combines UI interactions with backend validations, ensuring that user actions produce the expected effects both in the interface and in the underlying data and services. This provides the most comprehensive testing approach for validating complete user experiences.
