I am new to the selenium and I have been trying to start Selenium Hub and adding the node to the Hub using java. I have started it using command prompt but I want it to happen on its own. I am able to start the Hub but have no Idea how to add the Node.
Following is my code to start the Hub:
import org.openqa.grid.internal.utils.configuration.GridHubConfiguration;
import org.openqa.grid.internal.utils.configuration.GridNodeConfiguration;
import org.openqa.grid.web.Hub;
public class StartHub {
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
GridHubConfiguration configHub = new GridHubConfiguration();
configHub.host = "localhost";
configHub.port = 8060;
//GridNodeConfiguration configNode = new GridNodeConfiguration();
//configNode.host = configHub.host;
//configNode.port = 5300;
Hub hub = new Hub(configHub);
//configNode.getHubHost();
hub.start();
//System.out.println(configNode.getRemoteHost());
//hub.stop();
}
}
How to add a Node going forward ?
Selenium-Grid Server Version 2.x.x configuration.

HUB Grid HUB Running as a standalone server: Hub is a central point which distributing tests on several node-machines, which are registered to it for parallel execution.
Use GRID HUB Server:
- To distribute your tests over multiple machines or virtual machines (VMs).
- You want to connect to a remote machine that has a particular browser version that is not on your current machine.
Start HUB Server
- loadFromCommandLine(String[] args) - Go through my previous post.
- loadFromJSON(String resource) - resource
default/DefaultHub.json for instance
public class Grid_HUBServer {
public static String HUBIP = GRIDINFO.HOSTIP.toString();
public static Integer HUBPORT = 4444;
static String separator = "\n------------------------\n";
public static void hubServer() {
try {
GridHubConfiguration gridHubConfig = new GridHubConfiguration();
gridHubConfig.setHost( HUBIP );
gridHubConfig.setPort( HUBPORT );
gridHubConfig.setNewSessionWaitTimeout( 50000 );
File JOSNFile = new File(System.getProperty("user.dir")+"/gridHub.json" );
gridHubConfig.loadFromJSON( JOSNFile.toString() );
Hub hub = new Hub(gridHubConfig);
hub.start();
System.out.println("Nodes should register to " + hub.getRegistrationURL());
System.out.format("%s Running as a grid hub: %s\n" +
"Console URL : %s/grid/console \n", separator,separator,hub.getUrl());
System.out.println("Please Enter to stop service.");
System.in.read();
System.in.read();
hub.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
hubServer();
}
}
NODE [RC] has to post a request to HUB in order to register with it, by this URL - IP:Port//grid/register.
public class Grid_NODEServer extends Grid_HUBServer {
static Integer NODEPORT = 5555;
static String PROXYCLASS = "org.openqa.grid.selenium.proxy.DefaultRemoteProxy";
public static void nodeServer() {
try {
System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, CHROME_DRIVER_EXE );
System.setProperty(InternetExplorerDriverService.IE_DRIVER_EXE_PROPERTY, IE_DRIVER_EXE);
RegistrationRequest request = new RegistrationRequest();
request.setRole( GridRole.NODE );
File JOSNFile = new File(System.getProperty("user.dir")+"/registerNode.json" );
request.loadFromJSON( JOSNFile.toString() );
Map<String, Object> configuration = new HashMap<String, Object>();
URL remoteURL = new URL(String.format("http://%s:%d", HUBIP, HUBPORT) );
System.out.println("Remote URL : "+remoteURL);
configuration.put(RegistrationRequest.AUTO_REGISTER, true);
configuration.put(RegistrationRequest.HUB_HOST, HUBIP);
configuration.put(RegistrationRequest.HUB_PORT, HUBPORT);
configuration.put(RegistrationRequest.REMOTE_HOST, remoteURL);
configuration.put(RegistrationRequest.PORT, NODEPORT);
configuration.put(RegistrationRequest.PROXY_CLASS, PROXYCLASS);
configuration.put(RegistrationRequest.MAX_SESSION, 1);
//configuration.put(RegistrationRequest.CLEAN_UP_CYCLE, 2000);
//configuration.put(RegistrationRequest.MAX_INSTANCES, 1);
request.setConfiguration( configuration );
GridNodeServer node = new SeleniumServer( request.getConfiguration() );
SelfRegisteringRemote remote = new SelfRegisteringRemote( request );
remote.setRemoteServer( node );
remote.startRemoteServer();
System.out.format("Selenium Grid node is up and ready to register to the hub " +
"%s Running as a grid node: %s ", separator,separator);
remote.startRegistrationProcess();
System.out.println("Please Enter to stop service.");
System.in.read();
System.in.read();
remote.stopRemoteServer();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
nodeServer();
}
}
