🔍 代码审查结果@SamanthaKhan 你好！我对 PR #41 进行了详细的代码审查，发现了一些需要修复的问题。 ❌ 审查结论：不通过（存在 BLOCKING 问题）🚨 BLOCKING 问题1. 致命的业务逻辑错误：死循环条件检查位置： 当前代码存在严重的逻辑错误，会导致 custom provider 永远无法通过验证： // 第 576 行：外层条件
if cfg.AICfg.Model == "" {
switch cfg.AICfg.Provider {
case "deepseek":
cfg.AICfg.Model = "deepseek-chat"
case "qwen":
cfg.AICfg.Model = "qwen3-max"
case "custom":
if cfg.AICfg.BaseURL == "" {
return fmt.Errorf("自定义AI模型需要配置 API 地址")
}
// ❌ 这里的检查永远为 true！
if cfg.AICfg.Model == "" {
return fmt.Errorf("自定义AI模型需要配置模型名称")
}
}
}问题分析：
影响范围：
2. 违反 TDD 原则：未编写测试根据项目的
当前 PR：
验证： $ grep -rn "hydrateBacktestAIConfig" --include="*_test.go" .
# 返回空 - 没有任何针对该函数的测试3. 缺少业务需求验证
🔧 修复建议方案 1（推荐）：分离验证和默认值设置// 先为已知 provider 设置默认模型
if cfg.AICfg.Model == "" {
switch cfg.AICfg.Provider {
case "deepseek":
cfg.AICfg.Model = "deepseek-chat"
case "qwen":
cfg.AICfg.Model = "qwen3-max"
}
}
// 然后独立验证 custom provider 的必需字段
if cfg.AICfg.Provider == "custom" {
if cfg.AICfg.BaseURL == "" {
return fmt.Errorf("自定义AI模型需要配置 API 地址")
}
if cfg.AICfg.Model == "" {
return fmt.Errorf("自定义AI模型需要配置模型名称")
}
}优点：
📋 必需的测试用例修复前，请先添加以下测试（TDD 要求）： // api/backtest_test.go
func TestHydrateBacktestAIConfig(t *testing.T) {
t.Run("应该为 deepseek provider 设置默认模型", func(t *testing.T) {
// 测试：CustomModelName 为空 → 自动设置 "deepseek-chat"
})
t.Run("应该为 qwen provider 设置默认模型", func(t *testing.T) {
// 测试：CustomModelName 为空 → 自动设置 "qwen3-max"
})
t.Run("custom provider 必须显式配置模型名称", func(t *testing.T) {
// 测试：custom + Model 空 → 应该返回错误
})
t.Run("custom provider 必须配置 BaseURL", func(t *testing.T) {
// 测试：custom + BaseURL 空 → 应该返回错误
})
t.Run("应该保留用户显式配置的模型名称", func(t *testing.T) {
// 测试：用户设置了自定义模型名 → 应该保留，不覆盖
})
}✅ 修复步骤
📊 代码质量评估
💡 总结你正确识别了问题（deepseek/qwen 需要默认模型），但实现时没有充分考虑边界情况。建议按照上述步骤修复后重新提交。 如果有任何疑问，欢迎随时讨论！🙌 审查人： Claude Code |
