# =============================================================================
# 企微IT智能服务台 — 非文本消息处理测试
# =============================================================================
# 测试覆盖:
# 1. _get_non_text_display() — 各消息类型的展示文本生成
# 2. _get_non_text_reply() — 各消息类型的自动回复模板
# 3. _handle_non_text_message() — 非文本消息核心处理流程
# - 图片消息:正确存储 + 正确回复模板
# - 语音消息:正确存储 + 正确回复模板
# - 文件消息:正确存储 file_name/file_size + 正确回复
# - 位置消息:正确存储 location 字段 + 正确回复
# - 视频消息:正确存储 + 正确回复
# 4. 文本消息不受影响(回归测试)
# 5. WebSocket 广播格式验证
# 6. 非文本消息不触发 AI、不改变会话状态
# 7. wecom_callback.py 字段提取验证
# =============================================================================
