Robotframework + Google Chrome headless

Hello.java

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setBinary("/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary");
chromeOptions.addArguments("--headless");

WebDriver Driver = new ChromeDriver(chromeOptions);

Hello chrome headless
    ${options}=  Evaluate  sys.modules['selenium.webdriver'].ChromeOptions()  sys, selenium.webdriver
    ${options.set_binary}=  Set Variable  set_binary=/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary
    ${options.add_argument}=  Set Variable  add_argument=--headless
    Create WebDriver  Chrome  chrome_options=${options}
    
    Open Browser   http://www.google.com   chrome
    Wait Until Page Contains    ffgdfgdfgdfgdfg
    Close Browser

I found that the robot example won't work for me. I would replace the add_argument part with the following:

    ${chrome_options}=  Evaluate  sys.modules['selenium.webdriver'].ChromeOptions()  sys, selenium.webdriver
     Call Method    ${chrome_options}    add_argument    headless

For robotframework I found better solution - https://github.com/drobota/robotframework-xvfb

Exactly Below code worked for me, for headless chrome

    #my_create_webdriver   Chrome  ${options}
    create webdriver  Chrome  chrome_options=${options}
