I being trying to use the new headless mode for Google Chrome but I don’t know what I maybe be doing wrong.

This is my suite\_setup.robot

```
***Settings***
Library SeleniumLibrary
Library String
Library Collections
Library OperatingSystem
Library DateTime
Library FakerLibrary locale=pt_BR

***Variables***
${HEADLESS}= ${HEADLESS}
${TEARDOWN}= True
${URL}= ${URL}
${FAST_TIMEOUT}= 5
${TIMEOUT}= 30
${LONG_TIMEOUT}= 60
${HARD_TIMEOUT}= 90

***Keywords***

Open Chrome
    ${CHROME_OPTIONS}= Evaluate selenium.webdriver.ChromeOptions()
    Call Method ${CHROME_OPTIONS} add_argument --incognito    
    Call Method ${CHROME_OPTIONS} add_argument --disable-notifications   
    Call Method ${CHROME_OPTIONS} add_argument --new-window   
    Call Method ${CHROME_OPTIONS} add_argument --aggressive-cache-discard        
    Call Method ${CHROME_OPTIONS} add_argument --disable-application-cache

    Call Method ${CHROME_OPTIONS} add_argument --mute-audio
    Call Method ${CHROME_OPTIONS} add_argument --start-maximized
    Run Keyword If ${HEADLESS}==True With Headless ${CHROME_OPTIONS}
    Run Keyword If ${HEADLESS}==False Without Headless ${CHROME_OPTIONS}

With Headless
    [Arguments] ${CHROME_OPTIONS}
    Call Method ${CHROME_OPTIONS} add_argument --headless=new
    Open Browser ${URL} chrome options=${CHROME_OPTIONS}
    Set Window Size 1920 1080

Without Headless
    [Arguments] ${CHROME_OPTIONS}
    Open Browser ${URL} chrome options=${CHROME_OPTIONS}

```

As soon I run the following command `robot -d ./results -v HEADLESS:True ./Cases` I get this error in the terminal: `Calling method 'add_argument' failed: TypeError: ArgOptions.add_argument() got an unexpected keyword argument '--headless'`.

This is my requirements I’m using:

```
Faker==4.16.0
python-dateutil==2.8.1
robotframework==6.0.2
robotframework-faker==5.0.0
robotframework-pabot==2.15.0
robotframework-pythonlibcore==4.1.2

six==1.12.0
text-unidecode==1.3

wrapt==1.12.1
qase-robotframework==1.1.1

```

As far I as know the **new** headless mode is very easy to use. For example in the below test:

```python
***Settings***
Library SeleniumLibrary

***Test Cases***
Testing Headless Chrome
    Open Browser https://robotframework.org/ headlesschrome
    Sleep 5 seconds
    Capture Page Screenshot
    Close Browser

```

@HelioGuilherme66 I saw this option in the selenium documentation but I thought it still use the old headless mode. I was trying using the parameter `headless=new` because it is in the Google documentation.

OK, but the RF community always try to make things simpler 🙂

I have not been able to get the new functionality from Google to work with robot framework. That is using headlesschrome argument or headless=new. And with the new drivers from chrome the headlesschrome does not longer seem to work as they did a couple of months back.  
I’m probably just confused on what to use as of right now and hopefully I will get some clarity here at this forum in the future.

We started using headlesschrome here but the problems we had with the “normal” were still happening. For now, we have 6-7 test cases running with Firefox. For some reason, the headless firefox works in some way different than chrome.

There is option to create common keyword to run on multiple headless browser option.

headless Chrome or Firefox.

Below is the code snippet.

\*\*\* Keywords \*\*\*  
Open Headless Browser  
Set Environment Variable ${browser}  
Set Environment Variable ${url}  
${options} Evaluate sys.modules[‘selenium.webdriver’].${browser}Options()  
… modules=sys, selenium.webdriver  
Call Method ${options} add\_argument --headless  
Create Webdriver ${browser} ${options}  
Go To ${url}

Pass the browser name you want to be headless, along with URL value in the script run command.
