Getting error while running the selenium test cases with selenium grid?

Question

My browser invocation code is like:

else if(browserName.equals("chrome")) {
            System.setProperty("webdriver.chrome.driver", "/home/selenium-drivers/chromedriver");
            DesiredCapabilities capabilities = DesiredCapabilities.chrome();
            capabilities.setPlatform(Platform.LINUX);
            URL url_hub = new URL("http://my-remote-server-ip:4444/wd/hub");
            driver = new RemoteWebDriver(url_hub, capabilities);
            driver.manage().window().maximize();
            driver.get(url);
        }

Getting the following error while running the program :

Unable to create new remote session. desired capabilities = Capabilities [{browserName=chrome, version=, platform=WINDOWS}], required capabilities = Capabilities [{}] []1

@Dev yes .And I have got the console message "08:40:54.801 INFO - The node is registered to the hub and ready to use " — Sidhartha

Can you show me the commands how you started Hub & Node? Thanks — undetected Selenium

@Dev I am running the hub through Jenkins and the command I am using for node "java -jar selenium-server-standalone-3.4.0.jar -role node -hub my-server-ip:4444/grid/register " — Sidhartha

Here is the Answer of your Question:

Windows Platform

Start the Selenium Grid Hub. Confirm the log message:

14:25:50.350 INFO - Selenium Grid hub is up and running

Open grid console URL (in my case http://localhost:4444/grid/console) and observe the console.

Start the Selenium Grid Node & register it to the Hub:

java -Dwebdriver.chrome.driver=C:\Utility\BrowserDrivers\chromedriver.exe -jar C:\Utility\selenium-server-standalone\selenium-server-standalone-3.4.0.jar -role node -hub http://localhost:4444/grid/register

Look out for the Node Registration Logs:

14:33:12.354 INFO - Selenium Grid node is up and ready to register to the hub
14:33:12.409 INFO - Starting auto registration thread. Will try to register every 5000 ms.
14:33:12.409 INFO - Registering the node to the hub: http://localhost:4444/grid/register
14:33:12.756 INFO - The node is registered to the hub and ready to use

Here is own working set of code twisted a bit to fit into my local Windows 8 box as localhost:4444 settings:

System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setBrowserName("chrome");
cap.setPlatform(Platform.WINDOWS);
URL url = new URL("http://localhost:4444/wd/hub");
WebDriver driver = new RemoteWebDriver(url, cap);
driver.get("http://google.com/");
System.out.println("Title is : "+driver.getTitle());
driver.quit();

I get a result as:

Title is : Google
PASSED: test1

===============================================
Default test
Tests run: 1, Failures: 0, Skips: 0
===============================================

Let me know if this helps you.

I have followed all the above steps but getting "org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{browserName=chrome, version=, platform=WINDOWS}], required capabilities = Capabilities [{}] Build info: version: '3.0.1', revision: '1969d75', time: '2016-10-18 09:49:13 -0700' System info: host: 'arima-latitude-3460', ip: '127.0.1.1', os.name: 'Linux', os.arch: 'amd64', os.version: '3.13.0-117-generic', java.version: '1.8.0_131' Driver info: driver.version: RemoteWebDriver " this error.

Your OS is Linux, so you have to make certain changes accordingly. 1.Path of chromedriver (linux type absolute path & without extension). 2. Change Platform.WINDOWS to Platform.LINUX 3. Pass exact IP & port instead of http://localhost:4444/wd/hub

I have changed that in code ,now its working fine when I am running the program in local machine but still getting the same error while running the code on cloud.
