"""司机端小程序 fixture — 通过 subprocess 驱动 miniprogram-automator (Node.js)。
|
|
|
|
原理:
|
|
Python pytest → subprocess → node runner.js → miniprogram-automator
|
|
→ 微信开发者工具 → 小程序
|
|
返回 JSON: {"ok": true/false, "message": "...", "screenshot": "path"}
|
|
|
|
前置条件:
|
|
1. 微信开发者工具已安装 + 开启服务端口
|
|
2. npm install（在 tests/web/mini_program/automator/ 下）
|
|
3. uni-app 已编译为微信小程序
