• Design and development of an end-to-end test automation framework for a document processing pipeline across three business systems: LC, the life insurance contract system; DSK, the print control component; and EOS, the Enterprise Output System / Apollo/Cartago.
• Playwright-based E2E tests using Python/pytest for the complete document lifecycle: LC contract search ? creation of policy letter ? DSK print order control ? EOS document generation and PDF validation.
• Excel-driven test execution, where business users define test cases via Excel, including contract numbers, output schemas, module selection, and variable inputs. Results are written back automatically.
• Web dashboard using Flask with live log streaming, test selection, headed/headless mode, login credential input, parallel execution, and Excel upload.
• Page Object architecture with stable MUI/aria-label selectors, robust against CSS hash changes.
• Error detection for LC system messages, such as EBF and Java exceptions, with automatic documentation in Excel.
• Offline-capable distribution package: build script bundles Python virtual environment, Chromium browser, and all dependencies as a ZIP package for company computers without internet access.
• GitLab CI/CD integration with pipeline trigger directly from the dashboard.
• Automation of MUI/React SPAs with dynamic selectors, Keycloak SSO across multiple systems, Cartago editor control, and full offline capability despite corporate proxy restrictions.
