"lang" capabilities does not work for google chrome

[ksinapayen]

Google chrome is always launched in english, despite any robot configuration we tried.

In the ROBOT configuration

You can add capabilities (like “lang”) in “RequestedCapabilities” that is taken into account in "FinalCapabilities"

But you can't merge a capabilities (par exemple "goog:chromeOptions" )

{
"FinalCapabilities": {
"acceptInsecureCerts": ["true"],
"browserName": ["chrome"],
"goog:chromeOptions": ["{args=[start-maximized, --user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36], extensions=[]}"],
"goog:loggingPrefs": ["org.openqa.selenium.logging.LoggingPreferences@88ff2b28"],
"lang": ["fr-FR"],
"platformName": ["WINDOWS"]
},
"RequestedCapabilities": {
"goog:chromeOptions": ["{args=[--lang=fr-FR]}"],
"lang": ["fr-FR"]
}
}
