Issues with Chrome browser while starting it with the grid (webdriver)

[jyo rani]

Not sure what is going here.....

This is how i defined my chrome driver

public static WebDriver getChromeBrowser() throws
MalformedURLException
{ DesiredCapabilities capability=null;
System.setProperty("webdriver.chrome.driver", "src//main//resources//
chromedriver//chromedriver.exe");
capability= DesiredCapabilities.chrome();
capability.setBrowserName("chrome");
capability.setPlatform(org.openqa.selenium.Platform.WINDOWS);
return new RemoteWebDriver(new URL("http://selgrid:4444/wd/hub"),
capability);
}

cmd using to launch the node

java -jar selenium-server-standalone-2.20.0.jar -role node -hub
http://selgridin001:4444/grid/register -browser
"browserName=chrome,platform=WINDOWS"

Error when i start hub

You would need to tell the Grid where your chromedriver is available. You can take a look at my post to know more :  http://rationaleemotions.wordpress.com/2012/01/23/setting-up-grid2-and-working-with-it/

Thanks for the pointers,Here is what i tried, still no luck

I added the "System.setProperty("webdriver.chrome.driver", "C://chromedriver//chromedriver.exe");" where chrome driver resides on the slave box Intially it was System.setProperty("webdriver.chrome.driver", "src//main//resources//chromedriver//chromedriver.exe"); - not sure if this is required or not as chrome driver path is given while registering the node.

Now I don't see any errors when node is started,but the test fails very beginning with null pointer exception. Same test runs fine with IE and firefox. Here is the cmd i am using to run with IE browser

----------------------

java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://selgridin001:4444/grid/register -port 5555 -browser 

"browserName=internet explorer,version=8,platform=WINDOWS"

---------------------------------------

I can't understand where i am going wrong

public static WebDriver getChromeBrowser() throws MalformedURLException

{ DesiredCapabilities capability=null;

System.setProperty("webdriver.chrome.driver", "C://chromedriver//chromedriver.exe");

capability= DesiredCapabilities.chrome();

capability.setBrowserName("chrome");

capability.setVersion("19");

capability.setPlatform(org.openqa.selenium.Platform.WINDOWS);

return new RemoteWebDriver(new URL("http://selgridin001:4444/wd/hub"), capability);

}

cmd using to run with port 

java -jar selenium-server-standalone-2.20.0.jar -role node -Dwebdriver.chrome.driver="C:\Chromedriver\chromedriver.exe" -hub 

http://selgridin001:4444/grid/register -port 5556 -browser"browserName=chrome,version =19,platform=WINDOWS"

cmd using to run without port 

java -jar selenium-server-standalone-2.20.0.jar -role node -Dwebdriver.chrome.driver="C:\Chromedriver\chromedriver.exe" -hub 

http://selgridin001:4444/grid/register-browser"browserName=chrome,version =19,platform=WINDOWS"

[Krishnan Mahadevan]

From your test code you "can never set properties on a remote machine".

You can do that only if you are starting the grid and node "locally" on your machine. 

 Please pass the path to where chrome driver resides as a VM arg to the node (not grid if grid and node are different machines) and retry.

Okay..I removed the path of chrome driver in the code

public static WebDriver getChromeBrowser() throws MalformedURLException

{ DesiredCapabilities capability=null;

        capability= DesiredCapabilities.chrome();

capability.setBrowserName("chrome");

capability.setVersion("19");

capability.setPlatform(org.openqa.selenium.Platform.WINDOWS);

return new RemoteWebDriver(new URL("http://selgridin001:4444/wd/hub"), capability);

}

Here is the command using

C:\selenium-server>java -jar selenium-server-standalone-2.20.0.jar -role node -D

You forgot to include a space between browser and double quotes. It should be something like this. 

-browser browserName=firefox,version=3.6,maxInstances=5,platform=LINUX

Look at how the browser param was read by the Grid because you missed leaving a space between browser and browserName.

Much Thanks,It is working now.

I really appreciate your help!
