# =============================================================================
# IT智能服务台 — 审批意图检测（/approval/detect-intent）测试
# =============================================================================
# 测试覆盖：
#   1. 关键词预过滤逻辑（_keyword_prefilter 单元测试）
#   2. 降级兜底逻辑（_fallback_detect 单元测试）
#   3. 端点集成测试：
#      a. 关键词未命中 → 直接返回 false（不调 Dify）
#      b. 关键词命中 + Dify 高置信度 → is_approval_request=true
#      c. 关键词命中 + Dify 低置信度 → is_approval_request=false
#      d. Dify 调用失败 → 降级兜底
#      e. Dify 未配置 → 降级兜底
#      f. Dify 返回 is_approval=false → is_approval_request=false
#   4. /approval/keywords 端点测试
#   5. /approval/jump 端点测试
#
# Round 2 变更：所有端点已改用 success_response() 包装，
#   响应格式为 {code: 0, data: {...}, message: "success"}
#   测试断言已适配新格式：data["data"]["field"] 而非 data["field"]
