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": "^3.16.1",

"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.

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',
