Dec 1, 2024December 2024 – Ledger Live (LedgerHQ/ledger-live) focused on strengthening test reliability, CI stability, and critical path reliability in the transaction and swap flows. Implemented targeted testing infrastructure improvements and CI/test isolation for transaction broadcasting, alongside a strong bug fix to improve swap reliability. The work reduced flakiness, improved debuggability through richer artifacts, and delivered measurable business value by tightening end-to-end reliability for core user workflows. Key outcomes: - Testing Infrastructure Improvements and CI/Test Isolation for Transaction Broadcasting: introduced workflow-dispatch broadcast capability, isolated test broadcasts, separated DISABLE_TRANSACTION_BROADCAST flag into its own step, updated Playwright configuration, and enhanced artifact collection (video and screenshots in Allure). - Swap Confirmation Timeout Improvements (Bug Fix): increased swap confirmation timeout and added a stabilization delay to improve reliability in the swap/debit flow. Impact and Accomplishments: - Significantly reduced test flakiness and side effects in transaction broadcasting, enabling more deterministic CI runs and faster feedback loops. - Improved end-user reliability for critical transaction and swap paths, reducing failed transactions and customer support escalations. - Enhanced debugging capabilities through richer test artifacts, accelerating root-cause analysis. Technologies/Skills Demonstrated: - Playwright, CI/CD workflow customization, Allure reporting, test fixtures, and e2e testing practices. - Strong focus on business value through reliability engineering and end-user impact.
