Selenium Grid with safari browser - selenium

Question

Plese Help me
How do I instantiate the Safari in selenium grid
capabilities = new DesiredCapabilities();
// Version browser
capabilities.setVersion(versaoBrowser);
capabilities.setBrowserName("safari");
capabilities.setJavascriptEnabled(true);
// Platform test runner
capabilities.setPlatform(platform);
On the server is weel
-browser "browserName=safari,version=5,platform=WINDOWS,javascriptEnable=true"

Answer 1

If the question is about using Safari the new way, with SafariDriver over Grid2, then this would be the typical method I believe (more or less):
import org.openqa.selenium.*;
import org.openqa.selenium.remote.*;
import java.net.*;
DesiredCapabilities c = new DesiredCapabilities();
c.setBrowserName("safari");
/* you can then set version & platform as well, but the minimum is just browser. Maybe for Grid2 you need the others, but for remote web driver only, you don't.
*/
WebDriver d = new RemoteWebDriver(new URL("http://hubIpOrHostname:hubPort/wd/hub"),c);
and that should work. On the server side, I believe you just instantiate normally for Grid2 per the wiki docs (last I check, could be diff now):
//start hub
java -jar selenium-server-standalone-2.21.0.jar -role hub -port theHubPort
//start the node
java -jar selenium-server-standalone-2.21.0.jar -role node -hub http:
//172.22.6.198:4446/wd/hub -port theNodePort
however, seems that the current Grid2 doesn't offer Safari support. When I looked up the console for the registered node in hub, it didn't show icon for Safari. Maybe I missed something. I'll try adding platform and version next time to see if that makes a diff but think not.
Here's a snippet of the error I get for Grid2 with SafariDriver:
May 11, 2012 6:01:11 PM org.openqa.selenium.remote.RemoteWebDriver execute
INFO: Executing: [null, newSession {"desiredCapabilities":"Capabilities [{browse
rName=safari}]"}]
// Error: // Uncaught Exception: Typed variable declaration : Object constructor
: at Line: 7 : in file: : new RemoteWebDriver ( new URL ( "http:
//172.22.6.198:4446/wd/hub" ) , c )
Target exception: org.openqa.selenium.WebDriverException: Error forwarding the n
ew session cannot find : {browserName=safari}
Command duration or timeout: 109 milliseconds
To note: with webdriver, same code can be used for (standalone) remote webdriver execution vs grid, difference is that for remote you use remote server ip and with grid2, you use hub ip. SafariDriver works over remote webdriver, but currently doesn't seem to work over Grid2 yet.
remote webdriver startup:
java -jar selenum-server-standalone-2.21.0.jar [-port somePort]
//default port of 4444

Answer 2

I believe what you are asking for is something like this?
selenium = new DefaultSelenium("localhost", 4444, *safari,"http://google.com.au");
selenium.start();
I generally use WebDriver, but my understanding is capabilities are options for when you create an instance of a browser, not to open the browser itself. Though I could be wrong as I am not experienced with Selenium Grid.
EDIT: This and this might help.
