如何检查导致webdriver失败的原因

Question

我正在尝试执行这个简单的量角器示例，https://coryrylan.com/blog/introduction-to-e2e-testing-with-the-angular-cli-and-protractor和

webpack: Compiled successfully.
events.js:182
      throw er; // Unhandled 'error' event
      ^

Error: connect ETIMEDOUT 123.123.123.123:443
    at Object._errnoException (util.js:1024:11)
    at _exceptionWithHostPort (util.js:1046:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1185:14)

据我所知，这是一个错误造成的失败，而更新的网络驱动器管理器。我自己尝试手动更新，但是我仍然得到相同的错误。

PS C:\_pocs\ws_vsc\ng-pokedex-master> npm install -g webdriver-manager
C:\Users\dca\AppData\Roaming\npm\webdriver-manager -> C:\Users\dca\AppData\Roaming\npm\node_modules\webdriver-manager\bin\webdriver-manager

还有，其他试探性的

PS C:\_pocs\ws_vsc\ng-pokedex-master> webdriver-manager start
webdriver-manager: using global installed version 12.0.6
[16:20:31] W/start - the out_dir path C:\Users\dca\AppData\Roaming\npm\node_modules\webdriver-manager\selenium does not exist, run webdriver-manager update

我不认为这将是相关的，但以防万一，这里是来自上述项目的package.json。我试了两种“量角器”："~5.1.1“和5.1.2

}

另一件事，我刚刚想到的是，我有错误的代理配置，但我可以成功地运行npm安装，所以我认为这不会解释我的问题。顺便说一下，这是

H:\>npm config list
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.5.1 node/v8.8.1 win32 x64"

; userconfig C:\Users\dca\.npmrc
http-proxy = "http://XXX.vm.mycompany.net:3128/"
https-proxy = "http://XXX.vm.mycompany.net:3128/"
proxy = "http://XXX.vm.mycompany.net:3128/"

; builtin config undefined
prefix = "C:\\Users\\dca\\AppData\\Roaming\\npm"

; node bin location = C:\Program Files\nodejs\node.exe
; cwd = H:\
; HOME = C:\Users\dca
; "npm config ls -l" to show all defaults.

Answer 1

根本原因是代理后面的网络，您为NPM配置的代理不会在webdriver上生效(webdriver不会读取NPM的代理设置)

选项1：每次在webdriver命令中添加代理

webdriver-manager update --proxy=http://XXX.vm.mycompany.net:3128

注意:执行webdriver-manager start时还需要添加代理

选项2：在环境变量中配置代理，然后不需要在驱动程序管理器命令中添加代理。

将下面的环境变量添加到用户环境变量(当前登录用户，而不是系统环境变量)

HTTP_PROXY = http://XXX.vm.mycompany.net:3128/

HTTPS_PROXY = http://XXX.vm.mycompany.net:3128/

NO_PROXY = .mycompany.net,localhost,127.0.0.1

注意:这样做后，代理设置将影响从命令窗口执行的每个命令/程序(将访问网络)。
