WebDriver cannot be initialised when selenium-server-standalone is run as Windows service.
I'm connecting with Windows machine from Jenkins on centOS using SSH.
On Windows I installed selenium-server-standalone as service using nssm, so I run following command:
nssm start SeleniumWebDriver
The service is run as the same local Windows user that I'm using to log in.
The command is working correctly as I can see the process running in Task Manager and I'm able to access the hub and create the Chrome session.
But when the next step in Jenkins job is run, that is tests, it fails immediately because the WebDriver cannot be initialised.
When I run manually on Windows selenium-server-standalone (not as a service), the tests are executed because Chrome is being open. When run through service, Chrome is open but somewhere in the background (probably another session) and I and the tests cannot see the window.
How to change it to make the Chrome appearing so the WebDriver could be initialised and GUI actions be performed?

I have Selenium tests that I am running through Jenkins on a build server. The tests all run as expected in Chrome (using ChromeDriver) and Firefox (using FirefoxDriver). However, the tests don't run in Edge using EdgeDriver.
When the tests run it gives an error:
Microsoft Web Driver can't be used with the Built-In Administrator account or while User Account Control is turned off.
I have tried turning UAC on, but that no effect. I tried running the Jenkins service as a different user and that also had no effect. I've tried the suggestions from: MicrosoftWebDriver fails when constructing while running under TeamCity agent's windows service
I can run the tests in the same location from a command prompt, just not through Jenkins.
If you configure jenkins slave agent as a windows services, Will get the issues. Because Edge won't run as a headless browsers.
For avoid those issues. we are not suppose to set a slave agent as window services.
Follow the below steps for setup slave agent and then run your script:
***** Then download the agent.jar and place it under jenkins working directory("D:/Jenkins")
***** Open the command prompt as admin user and execute the commands.
java -jar agent.jar -jnlpUrl http://srv-cbe-com4:8080/computer/T/slave-agent.jnlp -secret 07ba92bb8017901287acb979cf30d40a45c17abd2c0edba5b2b3f17cc94915e8 -workDir "D:/Jenkins"
I'm hoping this is a simple issue to solve:
I have a dedicated machine that runs selenium with chromedriver. I can physically walk to the machine and type the following in a local terminal:
java -Dwebdriver.chrome.driver=chromedriver238 -jar selenium-server-3.11.jar
I can then go to any other machine on the network and kick off testing (in my case, codeception on jenkins) and it will sucessfully run my tests in chrome without a hitch.
However, if I try to run the above command without physically being at the selenium machine (ex, trying to ssh into the machine to run the command or making this command run as part of a supervisor process) then selenium has trouble starting the instance of chrome.
Has anyone run into this scenario before? Is there a way I can give 'interactive' access to the background script to allow it to open stuff on my screen?
Because when you physically walk to the machine and run the command. the selenium can get the desktop/window interface.
When use SSH, selenium lost the desktop/window interface, selenium have to start chrome under headless model, but your code not config to run as headless model. So the conflict come out.
you need to config your code to run with headless model.
I'm to getting the same scenario, when i try to start the selenium code on the machine A it works yet when i try to start selenium and run the scripts from machine B
(remotely connecting to machine A using ssh [ssh test#machine-a]) chrome instance doesn't start/launch and driver is getting null.
logs :
2020-02-27 12:04:27,319 INFO [LogWritter] Exception in beforeclass chrome driver instantiation , driver is null
2020-02-27 12:04:27,493 INFO [LogWritter] Exception in getting screenshot---java.awt.AWTException: headless environment
Any help/suggestion would be great !
I am trying to launch browser for automation testing(selenium) using jenkins on ubuntu OS. Test are running properly but browser is not launching seems like it is running headlessly.
I am able to fix this using this solution -
Added Xvfb plugin and added DISPLAY variable.
Running jenkins.war
from console using java -jar jenkins.war
As I know in Windows OS by checking "Allow service to interact with desktop" while jenkins installation we can fix this. So Is there any way we can do this on ubuntu by updating some configuration so we don't have run jenkins.war from console everytime.
There are two ways to facilitate the launch of browser on ubuntu OS.
1.First way - Configure your Jenkins nodes and add the ubuntu machine. Add the sshing details(username-password OR RSA key) of the target machine. This configuration is recommended if you are in cloud.
2.Second way(not recommended on cloud environments) -You have to run a Selenium standalone-Server (a standalone node), and register your remote WebDriver to it.
WebDriver driver = new RemoteWebDriver(new URL("http://ipOfUbuntuMachine:port/wd/hub"), capability);
I'm trying to solve a problem and I was hoping I could do it with Selenium Grid but I'm not entirely sure that it's possible. Here's my problem...I'm developing test cases using Selenium WebDriver and I need my tests to run on a Windows machine however the AUT runs on a Linux server. I have several tools that only run on Linux and I would like to be able to run some commands/tests on the Windows machine and others in the Linux server. For instance
Test Starts -> Firefox launches (Windows machine)
Login to site (Windows machine)
Run command in Linux server
Return running commands/tests on the Windows box.
Alternatively I could figure out how to run those commands remotely from a Windows machine but I'm not looking forward to doing that.
Out of the box, you cannot use selenium to run commands on your local machine. Selenium/Webdriver is a browser testing tool and can interact only with browser.
Updated Answer based on your comments
Common part to both ways (which I think you already know)
In your java code you should have the code for webdriver/selenium commands that will do step 1 and 2. Your java code should also the contain the logic/code to execute the linux commands as step 3. Step 4 should again be your webdriver command.
This test code should run from the linux server so that the java command execution will happen in the linux box.
Now the only pending part is the execution of test in remote machine.
Method 1 without using grid
Start the selenium server in the windows machine. Point your java tests to the selenium server running in this machine. If your windows machine IP is 10.0.0.1, you should initialize the webdriver object as
WebDriver wd = new RemoteWebDriver(new URL("http://10.0.0.1:4444/wd/hub"),DesiredCapabilities.Firefox());
This will send all your webdriver commands to the selenium server running in 10.0.0.1 on port 4444. Your tests will then get executed in the windows machine. For this to work, your linux server and windows machine should be in same network.
Method 2 using grid.
Its all the same as above, but instead of giving the ip/dns name of windows machine, you should give the ip/dns name of the hub machine. You should also have windows machine registered as an RC to that hub.
I think with AutoIT kind of windows frameworks, we can invoke C:\Windows\System32\cmd.exe to open a command prompt and run some .bat files. If it is Linux /bin/csh or /bin/bash myscript.sh.
I am trying to configure a Selenium testing through Bamboo. I am able to run Selenium scripts directly from command line, however it always fails if I run it through Bamboo remote agent. The error is:
: Could not start Selenium session: Failed to start new browser session: Error while launching browser
at com.thoughtworks.selenium.DefaultSelenium.start(DefaultSelenium.java:107)
I took some advice from the web, and checked "Allow service to interact with desktop" for Bamboo remote agent service. However, it does not work.
Anyone have other suggestions?
You must run Bamboo in Console Mode for this to work. Also, the build machine desktop must be active - and not covered or minimized if you want mouse simulations to work. I know right!
