When I launched Selenium tests In Jenkins with Maven on CentOS 7 I got:
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.)
Full error:
org.openqa.selenium.WebDriverException:
unknown error: Chrome failed to start: exited abnormally

I’d already installed Google Chrome on CentOS 7 Minimal as follows:
|
1 2 |
# wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm # yum localinstall google-chrome-stable_current_x86_64.rpm |
And Google Chrome version is 79.0.3945.117-1
Corresponding ChromeDriver 79.0.3945.36 was downloaded from here: https://chromedriver.chromium.org/downloads
The test server has CentOS 7 Minimal installed without graphical interface so in order to launch Selenium tests as Maven job in Jenkins on CentOS 7 the “headless” and “no-sandbox” options must be used in ChromeDriver settings (lines 23-26):

Good luck!
