To run with remote webDriver, need add two parameters, URL and Capabilities.
E.g. URL: the hub location
Capabilities: the remote webdriver type: firefox or chrome or IE. ..etc.
@BeforeTest
public void Setup() throws Exception {
URL url = new URL("http://localhost:4444/wd/hub");
Capabilities capabilities = DesiredCapabilities.firefox();
driver = new RemoteWebDriver(url, capabilities);
}
Run test case with RemoteWebDriver
