测试数据库结构一致性属性测试
|

**Validates: Requirements 9.1, 9.2**
|

|
||||
Property 8: 对于任意生产数据库(etl_feiqiu、zqyy_app)中的 schema 和表定义,
|
||||
对应的测试数据库(test_etl_feiqiu、test_zqyy_app)中应存在相同的 schema 和表结构。
|
||||
|
||||
测试逻辑:测试数据库创建脚本通过 \\i 引用生产 DDL 文件,
|
||||
结构一致性可以通过验证脚本引用的完整性来保证——
|
||||
即每个 \\i 引用的 DDL 文件在磁盘上实际存在。
