Walter Rocha Sevilla developed and enhanced the TDDLab Visual Studio Code extension in the UCB-TallerDeDesarrollo/TDDLab repository over three months, focusing on productivity and reliability for developers. He implemented workspace-scoped persistence for terminal buffers and timeline data, ensuring per-project state and preventing data loss during context switches. Using TypeScript, CSS, and modular programming, Walter refactored the TimelineView for improved UI consistency and introduced symbol-based test indicators. He also integrated AI-assisted TDD chat and strengthened error handling across features. His work improved build reliability, streamlined test execution, and modernized the extension’s architecture, resulting in a more stable and maintainable codebase.
December 2025 monthly summary for UCB-TallerDeDesarrollo/TDDLab focused on stability, user experience, and maintainability. Delivered workspace-scoped persistence for terminal buffers and timeline data in the TDDLab VSCode extension, enabling per-project state and preventing data loss when switching tabs/projects. Fixed a color initialization bug in TimelineView to derive colors from point properties, improving rendering accuracy and supporting related test cleanup/refactor. The changes enhance data integrity across workspaces, reduce user friction, and strengthen test reliability.
