Run Ranorex on Headless Endpoint

Question

I'm trying to set up an automatic web test environment using Ranorex and Selenium Web Driver. As the test will be integrated in Jenkings and run on a machine without graphical interface. I'm trying to set up an endpoint with headless browsers.

I start the selenium-standalone server and gekoDriver with the script:

java -jar -Dwebdriver.gecko.driver="C:\Utility\BrowserDrivers\geckodriver.exe" 
selenium-server-standalone-3.12.0.jar

How do you I manage to set up the Geko and Google Driver in headless mode?

Many thanks in advance.

Not sure about Ranorex but in Selenium, for Firefox, you just need to set the set_headless options to a boolean true or false to run the browser in headless mode.

For Python, it's like this

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.set_headless(headless=True)
driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("http://google.com/")
print ("Headless Firefox Initialized")
driver.quit()

Code and documentation and explanation is given in this post. Credits to the user Debanjan for this.

Hi. Thanks for your quick answer. I used Selenium in Java before, and I configured it similarly . My problem is that I need to configure this option in ranorex now — Pamana, May 15 '18 at 12:51

Found the solution. I had to add an endpoint configuration in Ranorex with the capabilities in JSON: For example for Firefox:

{
"browserName": "firefox",
    "moz:firefoxOptions": {  
         "args" : ['-headless']
     }
}

The endpoint will now start the gekoDriver with 'headless' option.

You have to provide the correct JSON capabilities.

For Firefox, the required JSON capabilities are:

{
    "browserName": "firefox",
    "moz:firefoxOptions": { 
        "args" : ['-headless']
    }
}

For Chrome, you have to use these capabilities:

{
    "browserName": "chrome",
    "chromeOptions": { 
        "args" : ["headless"]
    }
}

The other browser don't support headless (yet), as far as I know.
