Bug0 发布 QA Agent：缓存 Playwright 回放实现回归测试自动化
原标题：Bug0 Releases QA Agent to Automate Regression Testing With Cached Playwright Replays
AI 摘要
Linearbytes 发布 Bug0 QA Agent，一个源码可获取的 Playwright 库，用于智能体式浏览器回归测试。该工具将自然语言测试指令映射为 UI 操作，并在首次成功后缓存为具体 Playwright 操作存入 Redis，后续运行直接回放以降低 LLM 延迟；UI 变更导致回放失败时自动失效缓存并重新调用多模态智能体。断言验证不缓存，每次由 Claude、Gemini 等最多三个 LLM 共识及视觉模型评估，并以 Functional Source License 1.1 发布。

Linearbytes released Bug0 QA Agent, a source-available Playwright library for agentic browser regression testing. The AI agent associates the test instructions expressed in natural language to actions on the user interface, caches those when appropriate for faster CI replays, remapping them to test specifications when the user interface changes. Verification is based on consensus from up to three LLMs and evaluations from vision models. At one end of the spectrum, legacy approaches to web applic
