Rovo Dev CLI Ralph Wiggums Loop for Large Scale Test Refactoring

This post details the application of the Rovo Dev CLI's 'Ralph Wiggums Loop' for large-scale test refactoring. The workflow involved identifying target files using Rovo Dev, refining these into actionable Specs by linking to Confluence pages and previous PRs, and processing one file per iteration. Bottlenecks in local test execution were noted, with suggestions for batch testing. The loop was made failure-proof by flagging timeouts and identifying partially optimized files. A key lesson learned was the need to summarize learnings compactly for subsequent runs to manage Spec file size and maintain AI agent effectiveness. The outcome was 160 files of changes, with most tests working out-of-the-box and significant speed improvements.
