Interface Automation using global variables to solve the global problem of data dependencies

Today in the use of global variables to solve the global problem of data dependencies, we notice a huge hole. Executive order unittest framework, the order unittest script is loaded by default: Load ASCII codes according to the order, the order of numbers and letters are: 0-9, AZ, az. Therefore, in the beginning of the test method A will be preferentially executed, after a beginning to be performed.

I do not know in front of this rule, resulting in being given as follows:

AttributeError: 'NoneType' object has no attribute 'group'

For this reason error is generated, the second use case I need to use the login cookie, use the results of the second example was performed first, leading to pass the cookie is empty. Last Solution: adjust the operating sequence, a change of use-case name, so landing the first implementation use cases.

The second embodiment with the first run of FIG facie, cookie so printed is empty:

There can be seen at FIG. Code:

 

We define a global variable, COOKIE = None, then login cookies were a replacement operation. I.e. COOKIE = login_res.cookies. Then the next time a use case, get my fine pages of information, the cookies = COOKIE http request is transmitted to the inside. Thus solving the problem depends on a request to return a value to the request.

All code is as follows:

import unittest
from API_AUTO.tools.http_request import HttpRequest
import re

COOKIE = None


class TestHttp(unittest.TestCase):
    def setUp(self):
        pass  # abcdefghijklmnopqrstuvwxyz

    def test_Normal_login(self):
        '''正常登录'''
        global COOKIE
        url = 'https://www.ketangpai.com/UserApi/login'
        data = {
            "email": "[email protected]",
            "password": "A156829",
            "remember": 0
        }
        headers = {
            "User-Agent": " Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36",
            "Content-Type": "application/x-www-form-urlencoded",
        }
        login_res = HttpRequest().http_request('post', url, data, headers)
        if login_res.cookies:
            COOKIE = login_res.cookies
            print(COOKIE)
        try:
            self.assertEqual(1, login_res.json()['status'], '登录失败')
        except AssertionError as e:
            print('登录错误{}'.format(e))
            raise e



    def test_mooc(self):
        '''我的精品页面'''
        global COOKIE
        # print(COOKIE)
        url1 = 'https://www.ketangpai.com/Mooc/Mooc/index.html'
        headers1 = {
            "Referer": "https: // www.ketangpai.com / Main / index.html",
            "User-Agent": " Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36",

        }
        print(COOKIE)
        res1 = HttpRequest().http_request('get', url=url1, headers=headers1, cookies=COOKIE)
        try:
            pattern = '<img class=.*?\salt=(".*?").*?>'
            regular = re.search(pattern, res1.text, re.S)
            self.assertEqual('夏茂杰', eval(regular.group(1)), '进入我的界面失败')
        except Exception as e:
            print('错误是{}'.format(e))
            raise e

    def tearDown(self):
        pass
