before_scenario 中的 HOOK-ERROR：WebDriverException：消息：需要授权

Question

所以，大家好，我正在尝试在 browserstack 中运行一些 appium 测试。 （我正在使用Python行为）

所以我有以下问题：

项目部分结构：
-数据
--credentials.yaml --parameters.yaml

-帮手
--helpers.py

credentials.yaml 内容：

browserstack:
  userName: "superduperusername"
  accessKey: "superduperpaccesskey"

参数.yaml内容

browserstack_android:
  platformName: android
  framework: behave
  app: bs://roadtoeldorado
  platforms:
    - platformName: android
      deviceName: Samsung Galaxy S22 Ultra
      platformVersion: 12.0
  browserstackLocal: true
  buildName: bstack-demo
  projectName: BrowserStack Sample
  buildIdentifier: ${BUILD_NUMBER}
  debug: true
  networkLogs: true

helpers.py的内容

import pprint

from appium import webdriver
import yaml


def create_driver(driver_type):
    # Read desired capabilities from parameters.yaml based on driver_type
    with open("data/parameters.yaml", "r") as parameters_file:
        parameters = yaml.safe_load(parameters_file)

    with open("data/credentials.yaml", "r") as credentials_file:
        credentials = yaml.safe_load(credentials_file)

    if driver_type == 'local_android_emulator':
        capabilities = parameters.get('local_android_emulator', {})
        # Create and return the local driver instance
        return webdriver.Remote('http://localhost:4723/wd/hub', capabilities)

    elif driver_type == 'browserstack_android':
        capabilities = parameters.get('browserstack_android', {})
        browserstack_config = credentials.get('browserstack', {})
        capabilities.update({
            **capabilities,
            'browserstack.user': browserstack_config['userName'],
            'browserstack.key': browserstack_config['accessKey'],
        })
        # Create and return the BrowserStack driver instance
        pp = pprint.PrettyPrinter()
        print("\n")
        pp.pprint(capabilities)
        return webdriver.Remote(
            command_executor="https://hub-cloud.browserstack.com/wd/hub",
            desired_capabilities=capabilities
        )

    # Add more cases for other driver types if needed

    else:
        raise ValueError(f"Unsupported driver type: {driver_type}")

打印结果：

{'app': 'bs://roadtoeldorado',
 'browserstack.key': 'superduperkey',
 'browserstack.user': 'superduperusername',
 'browserstackLocal': True,
 'buildIdentifier': '${BUILD_NUMBER}',
 'buildName': 'bstack-demo',
 'debug': True,
 'framework': 'behave',
 'networkLogs': True,
 'platformName': 'android',
 'platforms': [{'deviceName': 'Samsung Galaxy S22 Ultra',
                'platformName': 'android',
                'platformVersion': 12.0}],
 'projectName': 'BrowserStack Sample'}

运行结果：
before_scenario 中的 HOOK-ERROR：WebDriverException：消息：需要授权

环境.py的内容

import os

from helpers.helpers import create_driver


def before_scenario(context, scenario):
    # Check for the environment variable to set the execution mode
    execution_mode = os.environ.get("EXECUTION_MODE", "local_android_emulator")
    context.execution_mode = execution_mode
    # Set up the driver based on execution mode
    if context.execution_mode == "local_android_emulator":
        context.driver = create_driver('local_android_emulator')
    elif context.execution_mode == "browserstack_android":
        context.driver = create_driver('browserstack_android')
    else:
        raise ValueError(f"Unsupported execution mode: {execution_mode}")
    # Add more modes as needed


def after_scenario(context, scenario):
    # Quit the driver after all scenarios have finished
    if hasattr(context, "driver") and context.driver:
        context.driver.quit()

几乎什么都试过了。更改为 JSON 格式，调用 JSON，但仍然没有任何结果（同样的错误）。我想我可能没有正确传递这些功能，因为如果我尝试将凭据直接放入 URL 进行身份验证，我会收到“缺少 deviceName”的信息。那么我做错了什么？ ：D

在您的代码中，能否将中心 URL 更改为以下基本身份验证格式：

“https://YOUR_BSTACK_USERNAME:[email protected]/wd/hub”
