The hard part of PR testing often comes before the test

Short summary

The author describes building QAMap, a local CLI tool that reads commits and diffs to describe behavior changes and surface QA questions about failures, boundaries, and state changes. Unlike LLM-based E2E test generators, it runs entirely locally without uploading code or making API calls. The tool is early-stage and the author acknowledges it frequently gets things wrong.

• •QAMap is a local CLI that analyzes diffs to surface QA questions about failure modes and boundaries
• •Runs entirely locally with no LLM calls or code uploads
• •Still early-stage; author seeks feedback on weak spots rather than claiming full domain understanding
