First let us understand what this problem is, and what all I have done when I got this error. Lets start from the very beginning.
Step1: I started a Selenium hub by this command:
F:\Selenium>java -jar selenium-server-standalone-2.41.0.jar -role hub -port 1111
Step2: I made a project in Eclipse IDE with the below code.
Code Snippet used
public class TestingSeleniumGrid {
private WebDriver driver;
@BeforeClass
public void setUp() throws Exception {
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("platform", Platform.WINDOWS);
driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),capabilities);
}
@Test
public void testSimple() throws Exception {
driver.get("http://google.com");
}
@AfterClass
public void tearDown() throws Exception {
driver.quit();
}
}
Step 3: I made this program run via TestNG. And I got the above ERROR which I mentioned in the starting of this post.
RESOLUTION
Before I start discussing the fix for the above error, lets try to start from the end. This is a general tip which we all should follow while coding or working with any sort of Programming language. You should read the error stack trace very deeply and again-and-again till you get some clue from it. Now coming back to the ERROR. 1. Check the port which you have mentioned while starting the hub , its 1111. 2. Now verify the same IP in your code its 4444. And thats where you are wrong. You have to make sure you have entered the same port and configuration in code and console while making the set up. You have to correct it, try changing the port in program like
driver = new RemoteWebDriver(new URL("http://localhost:1111/wd/hub"),capabilities);
OR change the command to
F:\Selenium>java -jar selenium-server-standalone-2.41.0.jar -role hub -port 4444
Happy Testing 🙂
