WebdriverIO:如何修复错误“未知错误:无法获得自动化扩展"?

本文介绍了WebdriverIO:如何修复错误“未知错误:无法获得自动化扩展"?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

注意:

提到这个重复的评论是为了当你维护自己的 chromedriver 和 selenium 安装时，但如果你使用 wdio-selenium-standalone-service 那些重复"的问题/解决方案不要没有帮助.希望这提供了上下文

The comments mentioning this as a duplicate are for when you're maintaining your own chromedriver and selenium installation, but if you use wdio-selenium-standalone-service those "duplicate" questions/solutions don't help. Hopefully this gives context

截至今天，我们在运行自动化 UI 测试时遇到了一个主要问题:

We have a major problem running automated UI tests as of today:

[13:35:36]      Failed to take screenshot on reject:     {"message":"unknown error: cannot get automation extension\nfrom unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html","type":"RuntimeError","seleniumStack":{"status":13,"type":"UnknownError","message":"An unknown server-side error occurred while processing the command.","orgStatusMessage":"unknown error: cannot get automation extension\nfrom unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html\n  (Session info: chrome= ...

我们在 wdio.conf.js 中使用这一行:

We use this line in our wdio.conf.js:

services: ['selenium-standalone']

这是我们的packages.json:

And this is our packages.json:

"dependencies": {
    "assign-deep": "^0.4.5",
    "chai": "^3.5.0",
    "eslint": "^3.17.1",
    "eslint-config-airbnb-base": "^11.1.1",
    "fs-extra": "^2.0.0",
    "graceful": "^1.0.1",
    "gulp": "^3.9.1",

    "eslint": "^3.16.1",
    "eslint-config-airbnb-base": "^11.1.0",
    "eslint-plugin-import": "^2.2.0"
  }

获得了与 wdio 相关的最新 npm 模块.对于任何 UI 测试(摩卡和黄瓜，我们目前都使用)，它始终失败.我们还没有尝试降级 Chrome，但可能很快就会有必要.

Got the latest npm modules for wdio-related pieces. It fails consistently for any UI tests (mocha and cucumber and we use both at the moment). We have not tried downgrading Chrome but it might be a necessity soon.

注意

  1. 感谢 github 上的用户 miroslawmajka
  2. 我有类似的问题，所以我正在使用他们的错误描述和解决方案

推荐答案

解决方案:通过将此 JSON 添加到配置文件来更新 chromedriver

1.以下是仅 chromedriver 的配置

对于那些有兴趣通过 WebdriverIO 使用 selenium-standalone 服务的人，我们已经修改了我们的 wdio.conf.js 以使用以下陈述:

Solution: update chromedriver by adding this JSON to config file

1. The following is the configuration for just chromedriver

For those who are interested in using the selenium-standalone service with WebdriverIO we have modified our wdio.conf.js to use the following statements:

{
    services: ['selenium-standalone'],
    seleniumLogs: './context/selenium-logs',
    seleniumArgs: {
        drivers: {
            chrome: {
                version: 2.28,
                baseURL: 'https://chromedriver.storage.googleapis.com'
            }
        }
    },
    seleniumInstallArgs: {
        drivers: {
            chrome: {
                version: 2.28,
                baseURL: 'https://chromedriver.storage.googleapis.com'
            }
        }
    }
}

这适用于我们使用最新版 Chrome 进行的设置.感谢您的提示，但由于我们使用 wdio-selenium-standalone-service 来管理 Selenium，因此我们不得不以不同的方式进行处理.

And that works with our setup with the latest version of Chrome. Thank you for the tip but we had to go about it a different way as we are using wdio-selenium-standalone-service for managing Selenium.

services: ['selenium-standalone'],
seleniumLogs: './context/selenium-logs',
seleniumArgs: {
    drivers: {
        // chrome: {
        //     version: 2.28,
        //     baseURL: 'https://chromedriver.storage.googleapis.com'
        // },
        chrome: {
            // check for more recent versions of chrome driver here:
            // http://chromedriver.storage.googleapis.com/index.html
            version: '2.33',
            //arch: process.arch,
            baseURL: 'https://chromedriver.storage.googleapis.com'
        },
        ie: {
            // check for more recent versions of internet explorer driver here:
            // http://selenium-release.storage.googleapis.com/index.html
            version: '3.6.0',
            //arch: 'ia32',
            baseURL: 'https://selenium-release.storage.googleapis.com'
        },
        firefox: {
            // check for more recent versions of gecko  driver here:
            // https://github.com/mozilla/geckodriver/releases
            version: '0.19.0',
            //arch: process.arch,
            baseURL: 'https://github.com/mozilla/geckodriver/releases/download'
        }
    }
},
seleniumInstallArgs: {
    drivers: {
        // chrome: {
        //     version: 2.28,
        //     baseURL: 'https://chromedriver.storage.googleapis.com'
        // },
        chrome: {
            // check for more recent versions of chrome driver here:
            // http://chromedriver.storage.googleapis.com/index.html
            version: '2.33',
            //arch: process.arch,
            baseURL: 'https://chromedriver.storage.googleapis.com'
        },
        ie: {
            // check for more recent versions of internet explorer driver here:
            // http://selenium-release.storage.googleapis.com/index.html
            version: '3.6.0',
            //arch: 'ia32',
            baseURL: 'https://selenium-release.storage.googleapis.com'
        },
        firefox: {
            // check for more recent versions of gecko  driver here:
            // https://github.com/mozilla/geckodriver/releases
            version: '0.19.0',
            //arch: process.arch,
            baseURL: 'https://github.com/mozilla/geckodriver/releases/download'
        }
    }
},
