-# Test register API fix - Core functionality test
-# 测试注册API修复 - 核心功能测试
-# 
-# 主要测试内容：
-# 1. 用户注册（无邮箱）- 应该成功
-# 2. 用户注册（有邮箱但无验证码）- 应该失败并返回正确错误信息
-# 3. 用户存在性检查 - 应该在验证码验证之前进行，返回"用户名已存在"
-# 4. 邮箱验证码完整流程 - 验证码生成、注册、重复邮箱检查
-# 5. 邮箱冲突检测 - 发送验证码前检查邮箱是否已注册
-#
-# 修复验证：
-# - 用户存在检查现在在验证码验证之前执行
-# - 邮箱冲突检测防止向已注册邮箱发送验证码
-# - 验证码不会因为用户已存在而被无效消费
-# - 错误信息更加准确和用户友好
-# - 返回正确的HTTP状态码（409 Conflict）
