How to run chrome in headless mode using cucumber for appian

Hi All,

I'm trying to get my automation tests to run in headless mode.

<cucumber.appian.version>23.3</cucumber.appian.version>

There's a section in the custom.properties to specify Chrome options

#Use comma separated values ex: username=appian,accessKey=,browserName=Safari,platform=mySecretAccessKeycOS 10.13,version=11.1,name=My Safari Test
#These two chromeOptions capabilities profile.default_content_settings.popups=0) and safebrowsing.enabled=true are hard coded capabilities.
#You'll need to set chromeOptions to blank to override those capabilities.
chrome.capabilities=

1.Has anyone had luck using above? If yes can you please share sample?

2.I've tried to setproperty,didn't work

I see that setting capabilities,options and driver initialization is done in BaseFixture class. Has anyone tried to successfully override the method?

Thanks!
