selenium RemoteWebDriver opens but ChromeOptions are not passed to Selenium Grid

Question

I have been trying to resolve a few issues with RemoteWebDriver and ChromeOptions using docker and selenium grid. The main issue is with the proxy but I half resolved that with a proxy pac file passing the pac file url as an arg into ChromeOptions. The below code runs great in docker debug and standalone locally but as soon as I try with the grid or deploy and run with bamboo the driver opens and I can see that ChromeOptions are not being passed because the poxy pac file is not being used and it's just frozen at org.openqa.selenium.remote.ProtocolHandshake createSession. I have been researching for a few weeks now and I am at a hard blocker with this now. I have seen some posts that DesiredCapabilities is deprecated but I have not found a way to implement ChromeOptions without it.

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--start-maximized");
    options.addArguments("--disable-infobars");
    options.addArguments("--proxy-pac-url= http://ProxyPacURL.com");
    DesiredCapabilities dc = DesiredCapabilities.chrome();
    dc.setCapability(ChromeOptions.CAPABILITY, options);
    driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), dc);

Answer 1

I was facing same issue and I have found the solution as below: We need to set "goog:chromeOptions" instead of "chromeOptions".

In your Java code, following line is present:

dc.setCapability(ChromeOptions.CAPABILITY, options);

If you navigate to ChromeOptions.CAPABILITY, you will notice that it is a constant with value "chromeOptions". This works fine for local web driver, but not for remote web driver (i.e. selenium grid).

Just change above line to this:

dc.setCapability("goog:chromeOptions", options);

Now when you execute your Java code, it will work fine and all your options will show their effect too.

I came across other pages, such as this, which referred to above solution.

Update to latest Selenium Jars, make sure your java is version 1.8 or greater, then you can pass ChromeOptions into the driver because DesiredCapabilities is deprecated. I am now able to run selenium docker nodes with selenium grid and all ChromeOptions arguments are now being passed to the containers.

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--start-maximized");
    options.addArguments("--disable-infobars");
    options.addArguments("--proxy-pac-url=http://myPacFile.com");
    options.addArguments("--no-sandbox");
    driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), options);

Answer 3

Try this:

const GRID_HOST = 'http://localhost:4444/wd/hub';

var options = new chrome.Options();
options.addArguments("--start-maximized");
options.addArguments("--disable-infobars");
options.addArguments("--proxy-pac-url=http://myPacFile.com");
options.addArguments("--no-sandbox");

driver = new webdriver.Builder()
.usingServer(GRID_HOST)
.forBrowser("chrome")
.setChromeOptions(options)
.build()
