## 使用Go进行自动化测试 ##

**在Linux上Go使用ChromeDriver进行Webdriver发生一个错误。**

panic: unknown error: unknown error: Chrome failed to start: exited abnormally.
      (unknown error: DevToolsActivePort file doesn't exist)
      (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

**解决方案：(添加粉红字体参数\[作用：解决非root无法调用chome问题\])**

chromeCaps := chrome.Capabilities\{  
// Prefs: imgCaps,  
Path: “”,  
Args: \[\]string\{  
// “–headless”,  
“–start-maximized”,  
“–window-size=1200x600”,  
`"--no-sandbox",`  
“–user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10\_14\_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36”,  
“–disable-gpu”,  
“–disable-impl-side-painting”,  
“–disable-gpu-sandbox”,  
“–disable-accelerated-2d-canvas”,  
“–disable-accelerated-jpeg-decoding”,  
“–test-type=ui”,  
\},  
\}

**环境：** centos7 go.1.14.4  
**使用到的工具下载链接：**

*  wget http://npm.taobao.org/mirrors/chromedriver/83.0.4103.14/chromedriver\_linux64.zip
 *  chrome浏览器安装自行百度
