在詹金斯身上运行selenium时出现问题

Question

1，在ubuntu上设置jenkins2、在ubuntu上设置硒3、创建硒测试脚本代码如下：

from selenium import webdriver
import time
driver=webdriver.Chrome(executable_path='/home/test/chromedriver')
driver.get('https://www.yahoo.com')
time.sleep(2)
screenshot=driver.save_screenshot("yahoo.png")
driver.quit()

4、成功在本地执行脚本5、尝试使用jenkins来运行脚本，在jenkinsbuildexecuteshell下，cd/home/testpython测试.py6、Jenkins构建失败控制台输出：

Running as SYSTEM
Building in workspace /var/lib/jenkins/workspace/test
[test] $ /bin/sh -xe /tmp/jenkins127263638261616263.sh
+ cd /home/test
+ python test.py

self.error_handler.check_response(response)

raise exception_class(message, screen, stacktrace)

(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.)

webdriver似乎无法启动，不知道如何解决这个问题并在jeninks上运行selenium。自动化新手，请告知，谢谢！

Answer 1

尝试在硒测试脚本中添加以下内容：

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument('--headless')

Answer 2

我认为问题出在chromedriver路径上。这个路径存在于jenkins节点上吗；executable_path="/home/test/cromedriver"？

提供在jenkins节点中可访问的chromediver的正确路径。
