pytest 读取yml文件测试数据

yml文件模版：

place_parent_order: &place_parent_order
  endpoint: /api/algo/order/place-parent-order
  method: POST
stop_parent_order: &stop_parent_order
  endpoint: /api/algo/order/stop-parent-order
  method: POST

test_place_parent_order:
  - testname: algo下单-条件twap下单-买
    tag: P0
    <<: *place_parent_order
    data: {}
    expect:
      code: 200
    after:
      <<: *stop_parent_order
      data: {"parentOrderId":129}
      expect:
        code: 200

测试入口读取文件：
