python接口自动化基础框架结构 ——分层

python接口自动化基础框架结构 ——分层

--bin 用于存放启动文件，如run.py

--cases cases目录，存放测试脚本

--data   YAML文件

--lib  存放各种附加的代码文件，如加密、链接数据库、生成测试脚本等

--report   存放报告

--setting.py 存放各种路径配置、服务器接口配置等等

--case_template.txt   模板文件，生成测试脚本的模板

————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

--setting.py 存放各种路径配置、服务器接口配置等等

import os

#设置目录的绝对路径
BASE_PATH = os.path.dirname(os.path.abspath(__file__))
DATA_PATH = os.path.join(BASE_PATH, 'data')   #yaml测试用例存放位置
CASE_PATH = os.path.join(BASE_PATH, "testcase") #测试用例存放位置
REPORT_PATH = os.path.join(BASE_PATH, 'report')  #测试报告存放位置

--case_template.txt   模板文件，生成测试脚本的模板

#接口自动化模板

--bin 用于存放启动文件，如run.py
run.py文件代码

import os
import sys
import unittest
from setting import *
from lib.set_case_file import create_case_file
import time
from BeautifulReport import BeautifulReport as BetRep

#将当前项目的目录加入零时环境变量，避免在其他地方运行时会出现引入错误
base_path = os.path.dirname(
    os.path.dirname(os.path.abspath(__file__))
)
sys.path.append(base_path)

#首先调用生成用例函数
create_case_file()
#查找用例
discover = unittest.defaultTestLoader.discover(
    start_dir=CASE_PATH,
    pattern='*.py'
)
#执行生成测试报告
tittle = '接口测试'
time_now = time.strftime('%Y-%m-%d-%H_%M_S')
runner = BetRep(discover)
runner.report(tittle,
              filename='{}_接口测试'.format(time_now),
              report_dir=REPORT_PATH
              )

lib  存放各种附加的代码文件，如加密、链接数据库、生成测试脚本等

MD5加密

import hashlib
def hash_code(pwd):
    md5 = hashlib.md5()   #获取md5对象
md5.update(pwd.encode('utf-8'))  #将传入的pwd编码后，更新MD5的状态
return md5.hexdigest()   #返回十六进制的MD5码

if __name__ == '__main__':
    print(hash_code('12345'))

set_case_file.py        生成测试脚本

from setting import  *
def set_res_data(res):
    if res:
        return res.lower().replace('":"', "=").replace('":', "=")

def create_case_file():
    file_lists = os.listdir(DATA_PATH)   #取出data目录下的所有文件
template_file = os.path.join(BASE_PATH,'case_template.txt')
    for fList in file_lists:
        if fList.endswith('.yaml') or fList.endswith('.yml'):
            #测试用例文件名和yaml文件名
data_file = fList.replace('.yaml','').replace('.yml','')
        #测试用例方法名
test_method_name = data_file.lower()  #方法名全小写
        #测试用例类名
test_class_name = test_method_name.capitalize()  #首字母大写
with open(template_file,'r',encoding='utf-8') as temp:
                content = temp.read()%{
                    'class_name' :test_class_name,
'method_name' : test_method_name,
'data_file' : data_file
                }
            test_case_file = 'test_{}.py'.format(data_file)
            #根据模板生成测试用例文件
with open(os.path.join(CASE_PATH,test_case_file),'w',encoding='utf-8') as f:
                f.write(content)

YAML文件
以小白接口为例，数据需替换

-   #用户注册
method: post
  url: http://hd215.api.okayapi.com/?s=App.User.Register
  data:
    app_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    username: xxx
    password: xxx

asserlist:
  - ret=200
  - err_code=0
  - err_msg=
