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

Thanks for the update headless chrome beta version 60 does not seem to work with websites which have self signed SSL Certificates.
Please update if Chrome Canary version works with url having SSL error.

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

    create webdriver  Chrome  chrome_options=${options}
