为核心金融模块补充单元测试和集成测试
## 新增测试文件 ### Wallet 模块（34 个测试用例） - service_test.go：8 个 Service 层测试 - repository_logic_test.go：14 个纯逻辑测试（applyEntry 核心逻辑） - repository_integration_test.go：9 个集成测试（数据库完整流程） - 测试覆盖率：11.0% → 36.1%（提升 25%） ### Order 模块（11 个测试用例） - service_test.go：11 个 Service 层测试 - 覆盖所有 Service 方法的依赖检查和参数验证 ### Payment 模块（29 个测试用例） - service_test.go：10 个 Service 层测试 - repository_logic_test.go：19 个逻辑测试（状态判断、常量验证） - 覆盖支付单复用、退款逻辑、输入验证 ## 测试基础设施 - database/test_helper.go：提供内存 SQLite 数据库创建函数 - 支持快速、隔离的测试环境 ## 测试策略 - 分层测试：Service 层（参数验证）→ Repository 逻辑层（纯函数）→ Repository 集成层（数据库） - 覆盖核心业务：余额变更、支付单复用、订单状态转换 - 边界条件：余额刚好够扣、差1分不够扣、零金额、并发场景 - 幂等性保证：渠道充值幂等、支付单复用 ## 文档 - docs/代码质量改进计划.md：详细的问题分析和改进计划（16周路线图） - docs/Repository层测试补充总结.md：测试工作总结和运行指南 ## 测试结果 - 所有测试通过（74 个测试用例） - Wallet 模块覆盖率提升至 36.1% - 为后续测试工作建立了完整的框架和规范 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
