How to run Robot Framework headless mode on Ubuntu server

[hello2...@gmail.com]

Hi, All,

   My test environment is Robot Framework on Ubuntu server, so we need to run headless mode. I have been working on it for couple of weeks without success. The same Robot Framework test case can be run on Mac with headless successfully. But it didn't work on Ubuntu server. Below is the code extract that works on my Mac, but not on Ubuntu server. I also tried Any thoughts and input are appreciated!

    Open Browser        https://www.google.com/    browser=headlesschrome
    Wait Until Page Contains    choose settings that are right for you
    close browser

The error was:

User can open home page :: as a user I can open the home page and ... | FAIL |

WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally

Ugh

Would you be able to run the test with --loglevel trace set from the command line and post the full stack trace? My gut feeling is that this is something related to Chrome or ChromeDriver so updating or downgrading few version might be worth of trying.

Tatu,

   Thanks much for your response and the information. Now I run the below robot test case on Ubuntu 18.04 desktop to open an url through firefox browser and it still failed. I can open the url on the Ubuntu desktop via firefox browser manually. Not sure why Robot can't open the URL via either firefox nor chrome. I ran robot with --loglevel TRACE

I attach the log files on the email. Thanks so much!

It looks like geckodriver or the Firefox did close unexpectedly when it tried to open the browser. Usually this means that Selenium, geckodriver or Firefox is not compatible with other components in the previous list. Unfortunately it's impossible to say what is incompatible with what based on the error message. To start with, I would make sure that Selenium and the geckodriver are the latest version available. Also, geckodriver creates a log file, either in the execution directory or ti the Robot Framework output directory. I would look the log file and see what type of hints it offers.
