February 2025: Stabilized and expanded QA automation across the erigon and cdk-erigon repositories, delivering clear business value through more reliable CI, faster feedback cycles, and broader QA coverage. Key deliverables include RPC test reliability fixes that stabilized CI by correcting test inputs, ensuring proper RPC daemon shutdown, chaindata preservation strategies, and removal of a flaky test case; plus targeted QA workflow enhancements to broaden test triggers and tighten workflows. Also advanced tip-tracking workflow robustness with explicit testbed scope, extended timeouts, and safer chaindata restoration. In cdk-erigon, QA pipeline cleanup removed obsolete tip-tracking tests and disabled failing RPC integration tests to reduce CI noise, and two new tip-tracking workflows were added to QA for Gnosis and mainnet, expanding coverage. Collectively these changes lowered flaky-test churn, accelerated delivery cycles, and improved QA throughput and reliability across critical ERIGON deployments.
