标题:
python实现接口自动化
代码实现自动化相干理论
代码编写脚本和工具实现脚本区别是啥?
代码:
优点:代码灵活方便
缺点:学习成本高
工具:
优点:易上手
缺点:灵活度低,有局限性。
总结:
功能脚本:工具
自动化脚本:代码
代码接口自动化怎么做的?
第一步:python+request+unittest;
具体描述?
第二步:封装、调用、数据驱动、日记、报告;
详细举例:
第三步:api\scripts\data\log\report\until…
脚本实现
利用代码编写自动化脚本的流程
1、抽取功能用例转为自动化用例
2、搭建环境(测试工具、)
3、搭建目录结构
4、编写脚本
5、实行脚本
6、设置持续集成
抽取功能转为自动化用例
搭建环境(测试工具)
1、python、Pycharm、requests、pymysql、parametrize
2、jenkins、jdk
提示:由于编写的自动化脚本,而自动化脚本编写之前功能已测试完毕,所以不需要在单独搭建项目环境。
搭建目录结构
代码编写
config.py
import os
# 服务器地址
HPST = "http://user-p2p-test.itheima.net"
# 项目目录路径
dir_path = os.path.dirname(__file__)
复制代码
api(api_register_login.py)
from config import HOST
class ApiRegisterLogin:
# 初始化
def __init__(self, session):
# 获取session对象
self.session = session # 实例化session,类下面的其他接口就能使用自己的session
# 图片验证码url
self.__url_img_code = HOST + "/common/public/verifycode1/{}" # {}是随机变量,用{}占用
# 短信验证码url
self.__url_phone_code = HOST + "/member/public/sendSms"
# 注册url
self.__url_register = HOST + "/member/public/reg"
# 登录url
self.__url_login = HOST + "/member/public/login"
# 登录状态url
self.__url_login_status = HOST + "/member/public/islogin"
# 获取图片验证码接口 封装
def api_img_code(self):
pass
# 获取短信验证码接口 封装
def api_phone_code(self):
pass
# 注册接口 封装
def api_register(self):
pass
# 登录接口 封装
def api_login(self):
pass
# 查询登录状态接口 封装
def api_login_status(self):
pass
复制代码
加上__,只能在当千模块里调用,其他py文件调用不了
接口封装 实现
# 获取图片验证码接口 封装
def api_img_code(self, random):
# 调用get方法,返回响应对象
res = self.session.get(url=self.__url_img_code.format(random))
return res
# 获取短信验证码接口 封装
def api_phone_code(self, phone, imgVerifyCode):
# 1、定义请求参数
data = {
"phone": phone,
"imgVerifyCode": imgVerifyCode,
"type": "reg"
}
# 2、调用请求方法
res = self.session.post(url=self.__url_phone_code, data=data)
return res
# 注册接口 封装
def api_register(self, phone, password, verifycode, phone_code):
# 1、定义请求参数
data = {
"phone": phone,
"password": password,
"verifycode": verifycode,
"phone_code": phone_code,
"dy_server": "on",
"invite_phone": ""
}
# 2、调用请求方法
res = self.session.post(url=self.__url_register, data=data)
return res
# 登录接口 封装
def api_login(self, keywords, password):
# 1、定义请求参数
data = {
"keywords": keywords,
"password": password
}
# 2、调用请求方法
res = self.session.post(url=self.__url_login, data=data)
return res
# 查询登录状态接口 封装
def api_login_status(self):
res = self.session.post(self.__url_login_status)
复制代码

断言
阐明:判定程序实行实际结果是否符合预期结果
示例:
提示:
捕捉异常的目的是为了将错误信息记录下来,
捕捉信息完成后,必须抛出异常

参数化
步骤
1.编写数据存储文件json
2.编写读取工具方法 read_json()
3.利用参数化组件进行引用 parametrize
1 .编写参数化文件(register_login.json)
心得:
1、根据模块来新建json文件(1个模块1个json文件)
2、最外侧利用{},模块下几个接口,编写几个key,值为列表
3、列表值中,有几组数据,就写几个{}
4、每组数据{}中,组成格式:阐明+参数+预期结果
几个接口几个key,这里有五个接口(图片验证码、短信验证码、注册、登录、登录状态接口)
每组数据组成格式:阐明+参数+预期结果
{
"img_code": [
{
"desc": "获取图片验证码成功(随机小数)",
"random": "0.123",
"expect_code": 200

2、编写读取数据工具(util.py)
from config import DIR_PATH
def read_json(filename, key):
# 拼接读取文件的完整路径 os.sep动态获取/ 还是 \ ,根据电脑的操作系统
file_path = DIR_PATH + os.sep + "data" + os.sep + filename
arr = []
with open(file_path, 'r', encoding="utf-8") as f:
# print(json.load(f))
# print(json.load(f).get(key)) [{},{},{}]----->[(),(),()]
for data in json.load(f).get(key):
arr.append(tuple(data.values())[1:])
print(arr)
if __name__ == '__main__':
read_json("register_login.json", "img_code")
# [('0.123', 200), ('123', 200), ('', 404), ('heloo123', 400)]
复制代码
参数化引用
难点1:错误次数锁定
# 登录接口 测试
@parameterized.expand(read_json("register_login.json", "login"))
def test04_login(self, keywords, password, expect_text):
try:
i = 1
if "error" in password:
while i <= 3:
r = self.reg.api_login(keywords=keywords, password=password)
i += 1
# 断言锁定
print("测试锁定:", r.text)
self.assertIn("锁定", r.text)
# 暂停60s
sleep(60)
# 测试登录成功
r = self.reg.api_login(keywords="13600001111", password="test123")
self.assertIn(expect_text, r.text)
# 1、登录接口
r = self.reg.api_login(keywords=keywords, password=password)
# 2、查询结果
self.assertIn(expect_text, r.text)
except Exception as e:
# 日志

# 抛异常

复制代码
查询登录状态,差别结果。
# 查询登录状态 测试
@parameterized.expand(read_json("register_login.json", "login_status"))

try:
