Parameter as in what? Are you asking about DesiredCapabilities?

Answer 1

If you are talking about the DesiredCapability for RemoteWebDriver, these are the basic parameters we pass on to the WebDriver.

1. Browser Name
2. Operating System
3. Browser Version
4. Operating System version

Below is the code to execute your test on the IE browser for windows 8.

DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
capability.setPlatform("WINDOWS_8");
capability.setVersion("9.0.4");
WebDriver driver = new RemoteWebDriver(new URL(hubURL), capability);

All these capabilities are not really mandatory based on your Grid setup. Check with your network system team to understand your Grid setup and choose your capabilities accordingly.
