selenium grid, creating node programmatically - selenium

Question

I have to create a java application that will start a node and connect it to the hub. So far I have been able to do so when the hub and node are on the same computer, but as soon as I try to connect on another machine hub, the registering process hang forever.
I tried different approach. To just call my bat file function in code.
String command = "java -jar selenium-server-standalone-2.26.0.jar -role node -hub http://192.168.0.11:4444/grid/register -port 4449 -Dwebdriver.chrome.driver=data\\driver\\chromedriver.exe -Dwebdriver.ie.driver=data\\driver\\IEDriverServer.exe -nodeConfig data\\configurations.json";
try
{
pr = Runtime.getRuntime().exec(command);
}
catch(Exception e)
{
e.printStackTrace();
}
The command work when called from a bat file, but in code it only works if the node and hub are on the same computer.
I also tried to use the RegistrationRequest.
RegistrationRequest req = new RegistrationRequest();
req.setRole(GridRole.NODE);
Map<String, Object> nodeConfiguration = new HashMap<String,
Object>();
nodeConfiguration.put(RegistrationRequest.AUTO_REGISTER, true);
nodeConfiguration.put(RegistrationRequest.HUB_HOST, "192.168.100.66");
nodeConfiguration.put(RegistrationRequest.HUB_PORT, 4444);
nodeConfiguration.put(RegistrationRequest.PORT, 5555);
URL remoteURL = new URL("http://" + "192.168.100.66" + ":" + 5555);
nodeConfiguration.put(RegistrationRequest.PROXY_CLASS, "org.openqa.grid.selenium.proxy.DefaultRemoteProxy");
nodeConfiguration.put(RegistrationRequest.MAX_SESSION, 1);
nodeConfiguration.put(RegistrationRequest.CLEAN_UP_CYCLE, 2000);
nodeConfiguration.put(RegistrationRequest.REMOTE_HOST, remoteURL);
nodeConfiguration.put(RegistrationRequest.MAX_INSTANCES, 1);
req.setConfiguration(nodeConfiguration);
remote = new SelfRegisteringRemote(req);
remote.startRemoteServer();
remote.startRegistrationProcess();
Same result, when I try to run on another computer hub, it hand at the registering process.
INFO - Registering the node to hub :http://192.168.100.66:4444/grid/register
any idea why? or how to do it.

Answer 1

I figured out my problem, which is really simple to fix. In my code I had
URL remoteURL = new URL("http://" + "192.168.100.66" + ":" + 5555);
I just needed to replace the ip address by my local ip address, not the hub ip address, and it worked. Which is weird cause I am pretty sure I took this code from somewhere online and he had a variable for the ip, and it was the same for remoteURL and the HUB_HOST

Answer 2

well. Not sure whether is suitable for you but I'd like to share approach I use on my project.
I've got remote machine with 192.168.4.52 IP and selenium stanadlone server running on it.
All selenium test suites I got locally.
So to run my selenium test suite on remote machine I simply use these settings in BaseSeleniumTest.java on my local machine:
....
#BeforeClass
public static void firefoxSetUp() throws MalformedURLException {
DesiredCapabilities capability = DesiredCapabilities.firefox();
driver = new RemoteWebDriver(new URL("http://192.168.4.52:4444/wd/hub"), capability);
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
driver.manage().window().setSize(new Dimension(1920, 1080));
}
#Before
public void homePageRefresh() throws IOException {
driver.manage().deleteAllCookies();
driver.get(propertyKeysLoader("login.base.url"));
}
#AfterClass
public static void closeFirefox(){
driver.quit();
}
where string
driver = new RemoteWebDriver(new URL("http://192.168.4.52:4444/wd/hub"), capability);
indicates IP of machine which I want to run my selenium test siute on.
I'm starting server on remote machine with this command:
java -jar selenium-server-standalone-2.26.0.jar in cmd before I run my test suite.
Hope it be helpful for you.
