Selenium Python-从Azure DevOps登录到应用程序

Question

MyScript在本地使用load_dontenv((时工作得非常好

我正试图将用户名和密码从Azure DevOps(库->SecretFile(传递到我的Python测试脚本，该脚本是.env

.env的内容(没有为.env.env命名的文件名(

USERNAME=[e-mail]
PASSWORD=examplepassword

YAML文件

script: | pip3 install python-dotenv displayName: 'Install dotenv'
task: DownloadSecureFile@1 inputs: secureFile: '.env'
script: | seleniumbase install chromedriver displayName: 'Install chromedriver'
script: | pip install pytest pytest-azurepipelines displayName: 'Install Pytest' env: 
USERNAME_YAML: $(USERNAME) 
PASSWORD_YAML: $(PASSWORD)
script: | pytest example.py --browser=chrome -n=8 -v -s --slow displayName: 'Login Test'

python脚本

import requests
from seleniumbase import BaseCase
from datetime import datetime
from selenium.webdriver.common.keys import Keys
import os
class smoke(BaseCase):
#.env file info
username=os.getenv('USERNAME_YAML')
password=os.getenv('PASSWORD_YAML')
def leadverification(self):

self.open("https://dev.cms.com")
self.update_text(self.cmsemail,self.username)
self.update_text(self.cmspword,self.password)
self.click(self.cmsloginbtn)

Answer 1

基于您的错误：

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

如果self.username或self.password为None(Python的"NoneType"(，则这将来自以下两行中的一行：

self.update_text(self.cmsemail,self.username)
self.update_text(self.cmspword,self.password)

如果下一条线路中有一条没有提取数据，那么这些线路就会出现问题：

username=os.getenv('USERNAME_YAML')
password=os.getenv('PASSWORD_YAML')

所以我会检查这些行是否返回字符串，否则就会遇到问题。
