http_request的类的单元测试
题目：1）针对YAPI网址写的http_request类做作业
2）提供2个接口：登陆和查询tools
3）针对登陆接口写4个用例：正常登陆，不输入密码，不输入账号，输入错误的密码
4）请利用任何一种方法实现用例的加载并执行
5）生成html的测试报告
注意：请在测试类里加上异常处理以及断言

改进—>因为登陆和查询等操作使用的是同一个账号，可以使用全局变量
缺点：关联性比较强，一步错步步错，因为可能查询比登陆先运行，或者说登陆失败
方法一：全局变量
import unittest
from auto_study.API_AUTO.Tools.http_request import HttpRequest
COOKIE=None#全局变量
class api_login(unittest.TestCase):#登陆接口的用例
def setUp(self):
#登陆
self.login_url = '********'
#查看详情的网址
self.fenlei_url= '********'
def test_normal_login(self):#输入正确的用户
global COOKIE#声明全局变量
login_data = {"email": "********", "password": "********"}
res=HttpRequest().http_request(self.login_url,'post',params=login_data)
if res.cookies:#如果cookie存在，则更新cookie
COOKIE=res.cookies
print(res.status_code)
print(res.text)
try:
self.assertIn('logout success...', res.text)
except AssertionError as e:
print("出错啦，断言错误是{}".format(e))
raise
def test_no_password(self):#不输入密码
data = {"email": "********","password": " "}
res=HttpRequest().http_request(self.login_url,'post', params=data)
print(res.status_code)
print(res.text)
try:
self.assertIn('密码错误', res.text)
except AssertionError as e:
print("出错啦，断言错误是{}".format(e))
raise

self.assertEqual(405, res.json()['errcode'])#res返回的是一个消息实体使用json转换为字典去取值
self.assertEqual('密码错误', res.json()['errmsg'])
# print(type(res.json()['errmsg']))#方法二：反射
import unittest
from auto_study.API_AUTO.Tools.http_request import HttpRequest

self.assertEqual('密码错误', res.json()['errmsg'])
# print(type(res.json()['errmsg']))#总结
在编写用例的时候，如果第二条用例需要用到第一条用例的返回结果里的某个值，处理方式有3种：
1.写到setup里
2.反射
3.全局变量
class GetDate:
Cookie="小郭"
if __name__ == '__main__':
print(GetDate.Cookie)#运行结果是：小郭
'''setattr可以直接把类里面的属性值做更改，setattr（类名，属性值，新值)'''
setattr(GetDate,"Cookie","小黄")
print(GetDate.Cookie)#类直接调用属性，运行结果是：小黄
'''hasattr是判断是否有这个属性值，hasattr（类名，属性值)'''
print(hasattr(GetDate,"Cookie"))#运行结果是：True
'''getattr是获取这个属性值，getattr（类名，属性值)'''
print(getattr(GetDate,"Cookie"))
'''delattr是获取这个属性值，delattr（类名，属性值)'''
delattr(GetDate,"Cookie")
print(hasattr(GetDate,"Cookie"))
