Selenium Grid 2 configured on Windows

Question

I install Selenium Grid 2 (selenium-server-standalone-2.1.0) on Windows 7 (I also tried Windows Server 2008) as 64-bit. I am testing WebDriver locally and everything is fine.

I start the hub using

java -jar selenium-server-standalone-2.1.0.jar -role hub

Adding a webDriver node for FireFox works, but everything else, like Google Chrome, throws an IllegalOperation exception.

For instance:

I am trying to add node for Chrome:

java -jar selenium-server-standalone-2.1.0.jar -role webDriver -hub http://127.0.0.1-00-00444 -browser browserName = chrome platform = windows version = 12 -port 5556

This shows how node is on the hub when you go to http: // localhost: 4444 / grid / console

I am adding code to call webDriver, for example:

DesiredCapabilities capability = new DesiredCapabilities(); capability.SetCapability(CapabilityType.Platform, "windows"); capability.SetCapability(CapabilityType.Version, "12"); capability.SetCapability(CapabilityType.BrowserName, "chrome"); IWebDriver driver = new RemoteWebDriver(new Uri("http://127.0.0.1:4444/wd/hub"), capability); 

I get the exception almost immediately:

{"cannot find: {platform = windows, browserName = chrome, version = 12}"}

It seems that node is not even found. I'm new to this, is that what I missed in setting up? (Internet Explorer does the same, and changing versions don't seem to help).

I searched for hours and hours, but nothing matching the exception seems to be my problem.

Answer 1

An exception IllegalOperation {"cannot find: {platform = windows, source_name ... is caused by the lack of matching (it never reaches Node).

If I use the configuration file when starting node, which explicitly indicates the platform and browser, for example:

 { "capabilities": [ { "browserName":"firefox", "maxInstances":1 }, { "browserName":"chrome", "platform":"WINDOWS", "maxInstances":1 }, { "browserName":"internet explorer", "version":"9", "platform":"WINDOWS", "maxInstances":1 } ], "configuration": { "cleanUpCycle":2000, "timeout":30000, "proxy":"org.openqa.grid.selenium.proxy.WebDriverRemoteProxy", "maxSession":5, "url":"http://[myIP]/wd/hub", } } 

and run the hub with this line:
java -jar selenium-server-standalone-2.2.0.jar -role webdriver -nodeConfig myconfig.json -hub http: // [myIP]: 4444 / grid / register

and create these features:

 DesiredCapabilities capability = new DesiredCapabilities(); capability.SetCapability(CapabilityType.Platform, "WINDOWS"); capability.SetCapability(CapabilityType.BrowserName, "internet explorer"); 

Then the test works (you must set all zones in IE to protect them).
Notabene I noticed that Windows is UPPERCASE, like in WINDOWS, or you get an error.

Answer 2

The documents do document this, but it is unclear.

 java -jar selenium-server-standalone-2.1.0.jar -role webDriver -hub http://127.0.0.1:4444 -browser browserName=chrome platform=windows version=12 -port 5556 

Must be:

 java -Dwebdriver.chrome.driver="C:\Users\Mike\Documents\Java Libraries\Selenium\chromedriver\chromedriver.exe" -jar selenium-server-standalone-2.1.0.jar -role webDriver -hub http://127.0.0.1:4444/grid/register -browser "browserName=chrome,platform=WINDOWS,version=12" -port 5556 

You are missing the grid/register from the hub url. Also, if you pass multiple arguments to -browser , they must be enclosed in quotation marks and separated by commas without spaces. You also need to pass the webdriver.chrome.driver property webdriver.chrome.driver same way as I did.

You can verify that it is successfully registered by going to your browser and clicking:

 http://localhost:4444/grid/console 

And as a side element, this is another way to declare the desired features:

 DesiredCapabilities dc = DesiredCapabilities.chrome(); dc.setVersion("12"); dc.setPlatform(Platform.WINDOWS); 

Answer 3

Try lowering the conditions for the chrome version and operating system:

Your node registration code will be as follows

 java -jar selenium-server-standalone-2.1.0.jar -role webDriver -hub http://127.0.0.1:4444 -browser browserName=chrome -port 5556 

And to create your browser:

 DesiredCapabilities capability = new DesiredCapabilities(); capability.SetCapability(CapabilityType.BrowserName, "chrome"); 

or

 DesiredCapabilities capability = DesiredCapabilities.chrome(); 

Your Chrome may have been updated without your notice, or that the version number “12” is not suitable for your installed version. If it works under these conditions, try adding "Platform = WINDOWS" and "Version" CapabilityTypes with new combinations.

Answer 4

You can set

 driver.quit(); 

at the end of your script

Answer 5

 Lets consider Hub running on Machine-A whose IPAddress is = 192.168.10.10 default port no. 4444. Lets Node running on Machine-B whose IPAddress is = 192.168.10.20. Lets consider operating System on HUB and Node is installed on drive C:\ (C-Drive). create a folder named selenium on c:\ as c:\selenium. keep binaries of IExplorer.exe, chromeDriver.exe and Selenium-Standalone-server2.10.0.jar. (on both machine A and B). configuring HUB on Machine-A 1- open Command prompt 2- go to folder selenium using i type cd\ then enter ii type c: then enter iii c:> cd selenium then enter 3- java -jar selenium-server-standalone-2.20.0.jar -role hub Configuring NOde on Machine - B 1- open Command prompt 2- go to folder selenium using i type cd\ then enter ii type c: then enter iii c:> cd selenium then enter 3- java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://192.168.10.10:4444/grid/register -port 5560 -browser browserName=chrome,maxInstance=4,platform=WIN8_1 -Dwebdriver.ie.driver=c:\selenium\ChromeDriver.exe your node will get register with Hub on port 5560. Test Case will become as- package testCase; import static org.junit.Assert.*; import java.net.URL; import java.util.concurrent.TimeUnit; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.remote.DesiredCapabilities; import org.openqa.selenium.remote.RemoteWebDriver; public class Avinash_Google_Chrome { WebDriver driver; String baseUrl , nodeUrl; @Before public void setUp() throws Exception { nodeUrl = "http://192.168.10.20:5560/wd/hub"; //Machine-A IPAdress with Port No. DesiredCapabilities capability = DesiredCapabilities.chrome(); driver = new RemoteWebDriver(new URL(nodeUrl),capability); driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES); } @After public void tearDown() throws Exception { driver.quit(); } @Test public void test() throws InterruptedException { driver.get("https://www.google.co.in"); Thread.sleep(3000); driver.findElement(By.linkText("Gmail")).click(); Thread.sleep(3000); driver.findElement(By.id("Email")).sendKeys(" [e-mail] "); driver.findElement(By.id("Passwd")).sendKeys("********"); driver.findElement(By.id("signIn")).click(); Thread.sleep(6000); } }
