接口测试的核心要素：发送接口请求→解析接口响应→检验接口测试结果。

之前常用的简单测试用例，举个栗子：

import requests    def test_login():        url = http://www.senbaba.cn        method =POST        headers = {'content-type': 'application/json',                   'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko',                   'Accept':'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*',                   'Accept-Language':'zh-CN'}        data = {"uname":"18888888888","pwd":"123456"}        resp = requests.request(method,url,headers=headers,data=data)        #解码json格式数据        dicts=json.loads(a.text)        code=a.status_code        #对比返回值        self.assertEqual(code,200)        self.assertEqual(dicts['status'],'ok')        self.assertEqual(dicts['error'],None)

使用yaml让代码和用例分离，举个梨子：

yaml配置

name: loginrequest:    url: http://www.senbaba.cn/login    method: POST    headers:        Accept: application/json, text/javascript, */*; q=0.01        X-Requested-With: XMLHttpRequest        User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36        Referer: http://www.senbaba.cn/loginpage        Accept-Encoding: gzip, deflate, sdch        Accept-Language: zh-CN,zh;q=0.8    json:        uname: "1888888888"        pwd: "123456"validators:    - {"check": "status_code","expeted":200}

# /usr/bin python#coding=utf-8import yaml,requests,jsond = open('testcase.yaml')e = yaml.load(d)request = e['request']name = e['name']method = request['method']url = request['url']headers = request['headers']data = request['json']re = requests.request(method,url,headers=headers,data=data)
