April 2025: Focused on stabilizing the SDK CI pipeline and expanding interactive testing capabilities. Delivered CodeSandbox integration for SDK interactive examples, enabling direct testing in CodeSandbox by permitting .csb.app hosts in Vite config across SDK example configurations. Hardened end-to-end test safety by defaulting keep-passing-screenshots to false in both manual and scheduled GitHub Actions runs, reducing accidental updates. Completed cleanup of the dashboard feature flag after rollout, removing enableDashboardAfterRenderDetection and related code, tests, and defaults. These changes improve CI reliability, developer feedback loop, and codebase hygiene, with short-term risk mitigations and long-term maintainability gains.

November 2024 monthly performance summary for gooddata-ui-sdk. Focus was on strengthening testing, CI/CD reliability, and build efficiency. Key deliverables include End-to-End Testing and CI/CD Improvements with isolated tests for sdk-backend-tiger, new Docker Compose configurations, updated scripts, and PR-driven e2e testing triggers, complemented by a dedicated e2e workflow, test filtering, and environment setup actions to stabilize and accelerate end-to-end validation. Also implemented Rush Cache Integration and Versioning Strategy to improve build efficiency by deriving version information from package.json during post-build. In response to cache-related issues, the team performed a Rush Cache Back-out / Rollback to revert a previous integration, and temporarily Disable Rush Cache to restore a stable prebuild flow while work continues. Additional alignment work included backporting node and Rush setup actions to release branches to ensure consistent environments.
