ChromeDriver doesn't open in jenkins - selenium

Question

I created a selenium cucumber framework that has a test.
The test needs to open chromeDriver, and it is working when I run it in my IDE without any problems.
When I run the project in Jenkins, although the test runs, the chromeDriver doesn't open at all.
The console log is:
17:32:14 Starting ChromeDriver 89.0.4389.23
(61b08ee2c50024bab004e48d2b1b083cdbdac579-refs/branch-heads/4389#{#294})
on port 4816
17:32:14 Only local connections are allowed.
17:32:14 Please see
https://chromedriver.chromium.org/security-considerations for
suggestions on keeping ChromeDriver safe.
17:32:14 ChromeDriver was started successfully.
Of course, this log is shown in my ide with the difference that chromeDriver opens in IDE mode and doesn't open in Jenkins mode.
What can I do?

Answer 1

First of all you should add more description, like:
what language do you use?
how start driver in your code?
do you use local driver or remote one?grid or selenoid?
do you use --headless mode on jenkins?
does jenkins have Xs for running browser?
There's bunch of solving, but each of them is based on more particular description:
Best way, but a bit tricky/expensive:
launch own Grid/Seleloid server on ec2 instance on any cloud platform you like: GCP, AWS, Azure, DigitalOcean etc
install docker and launch selenoid intance
launch selenoid application by downloading from github release page:
chmod +x cm
./cm selenoid start --vnc
get its IP and provide it to your driver creation command
which looks like that:
java:
WebDriver driver = new RemoteWebDriver(new URL(SelenoidIP/wd/hub), firefoxOptions);
driver.get("http://www.google.com");
driver.quit();
ruby:
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :remote, url: SelenoidIP/wd/hub
driver.get "http://www.google.com"
driver.close
python:
from selenium import webdriver
driver = webdriver.Remote(
command_executor=SelenoidIP/wd/hub)
driver.get("http://www.google.com")
driver.quit()

Update:
I found a better solution.
Start Jenkins as a process from command line, not as a service, to get Chrome to open.
https://stackoverflow.com/a/41457823/1691651
command line commands:
Jenkins.exe stop
java -jar Jenkins.war
To save your Jenkins configurations, create an Environment Variable for JENKINS_HOME that points to location listed on the "Configure Jenkins" setting.
Old answer:
This also happened to me in webdriver.io when using the "chromedriver" service. To solve it, I had to manually download the chromedriver at https://chromedriver.chromium.org/downloads and then run it via a terminal--I don't know why that fixed it.
I don't need to run chromedriver separately in a terminal when testing via command line on the same EC2 instance.
