生产是 MySQL 8、测试是 SQLite,两者的方言差异在本地完全测不出来。今天为此 付出了两次代价: 1. `ORDER BY ck_checked_at ASC NULLS FIRST` 在 SQLite 上完全正常,本地 258 条 全绿,一部署到生产第一次巡检就 1064 语法错误(MySQL 不支持 NULLS FIRST); 2. P1b 自动重登的结算复用调度器事务读取,在 SQLite 下看不出问题,但在 MySQL 的 REPEATABLE READ 下读到的是批次开始前的快照 —— 10 条实际成功的重登全部被记成 失败。SQLite 的读一致性与 MySQL 不同,这类问题跑一万遍也复现不出来。 改动: - 新增 tests/support/db.py:测试专用引擎/会话工具,连接串从 .env 读取, 默认指向独立的 douyu_login_test 库; - 新增 tests/conftest.py:会话级建好表结构,每个用例前后清空所有表做隔离; - 根 conftest.py 接管连接串设置:它在 pytest 收集阶段最先执行,在这里把 DATABASE_URL 指向测试库,应用模块首次 import 拿到就是 MySQL,不依赖任何 import 顺序(原先这里是 sqlite:// 兜底,改造后会变成「先建 SQLite engine 再打补丁换成 MySQL」,顺序一变就静默跑错库); - 21 个测试文件的 setup 样板统一改用共享测试引擎; - 两个迁移测试改为在临时库 douyu_login_mig_<随机> 上跑完整 alembic upgrade head, 跑完 drop —— 迁移脚本本身也终于在 MySQL 上被验证; - dev.sh 与 README 的过时说明一并更新(原先写着「不需要 MySQL / .env 配置」; 「测试各自建 SQLite 内存库」)。 安全与易用: - 测试库名与开发库同名时**直接拒绝运行**(clear_tables 会 DELETE 所有表, 一旦 TEST_MYSQL_DATABASE 被指到 douyu_login 就是数据灾难); - 连不上 MySQL 时给出可操作提示(先 ./dev.sh 起库 / 用 TEST_MYSQL_DATABASE 覆盖), 而不是抛一段 SQLAlchemy 原始堆栈。 验收: - 全量 301 条通过,连跑两次结果一致(隔离有效),耗时约 12.5 秒(原 SQLite 约 3.6 秒); - 单文件独立运行通过(不依赖全量执行顺序); - `grep -rn sqlite tests/ conftest.py` 已无实际用法; - **方言确实生效**:临时把一条查询改回 `NULLS FIRST`,13 条测试立刻变红(含运行期 失败),还原即恢复;这条由 test_generated_sql_is_mysql_compatible 长期守着。 代价(已在 README 与规划附录 C.2 记明):跑测试前必须先有 MySQL,pre-push 钩子 同理;CI 需要 service container。
