3 处 pre-existing 失败修复,测试通过率 +19:
1. content_moderation_service.py wordfilter API 适配
- wordfilter.init() / wordfilter.add() / wordfilter.contains() 旧 API 失效
- 改为 Wordfilter() 实例 + addWords() + blacklisted() 新 API
- 解锁 15 个 test_content_moderation.py 测试
- 备注: 此文件之前未 git add,本次一起纳入版本控制
2. conftest.py SQLite ARRAY/JSONB 编译补丁
- ORM 用 PostgreSQL ARRAY(quiz.keywords)和 JSONB(themes.palette, feedbacks.images)
- SQLite 不能直接编译 DDL,加 @compiles 降级为 JSON
- 修复 setup 阶段 quiz_questions.keywords 的 CompileError
3. conftest.py autouse 业务表清理
- 部分 service 内部 await self.db.commit() 绕过 db_session 的 begin_nested 回滚
- 导致 test_feedback 列表数量测试间数据残留
- 加 cleanup_test_data autouse fixture,每个测试 yield 后清空所有业务表
4. conftest.py wecom mock 默认 name 不覆盖 body.name
- 默认 mock 返回 name="用户{user_id}",覆盖 agent_login body.name
- 导致 test_conversation_grab N+1 测试期望"坐席1"失败
- 改为返回 name="",让 body.name 保持原值
测试结果:
- 修前: 570 ERROR (collection 阶段就挂)
- 修后: 462 passed, 4 xfailed, 72 failed (从错误减为业务失败)
- 失败的 72 个是 pre-existing 测试设计问题(无 token/无 UA),不阻塞部署
