接口框架项目实战-pytest（五）yaml用例封装

yaml文件规则说明.txt

bash 复制代码

1、yaml 文件一级目录必须包括 name、request、extract、validate
2、在request一级目录下二级目录 必须包括 method、url
3、如果需要做接口关联的话，必须使用一级关键字：extract
get 请求 params 传参
post 请求
 json传参，通过json关键字
 表单传参 通过data关键字
 文件格式 通过files关键字
如 json提取
  extract:
      access_token: access_token
  正则表达提取
    extract:
      access_token: '"access_token":"(.*?)"'
当需要使用随机参数时 可以调用common_util.py 中get_random_value 方法
如
name: "ms${get_random_value(100,200)}"

common_util.py

import random


class CommonUtil:
    def get_random_value(self,min,max):
        return random.randint(int(min),int(max))
