Unable to run Tests parallel using Grid2

[Raghuram]

I am unable to run tests using grid2. This are the steps i followed to run the tests.

Steps followed

1. invoked the hub by " java -jar selenium-server-standalone-2.20.0.jar -role hub"
   
2. Invoked the node browser specific " java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://localhost:4444/grid/register -port 5556 -browser "browserName=firefox,version=11.0,maxInstances=5,platform=WINDOWS" "
3. Invoked another node browser specific " java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://localhost:4444/grid/register -port 5557 -browser "browserName=iexplore,version=11.0,maxInstances=5,platform=WINDOWS" "
4. checked the nodes by checking the URL " http://localhost:4444/grid/console "
   
5. I have took some sample code from the net here is the code
   

File : SeleniumGridDemo1.java

package test;

@BeforeClass

selenium = new DefaultSelenium(host, Integer.parseInt(port), browser,url);

selenium.start();

selenium.open(url);

}

@AfterClass

public void tearDown() {

selenium.stop();

}

@Test

public void test_first() {

//selenium.open("/");

selenium.type("q", "First");

selenium.click("btnG");

}

@Test

selenium.type("q", "second");

selenium.click("btnG");

}

Can some one please help me in solving the issue

Thanks

The problem is because of the way in which you are starting off your webdriver nodes

Invoked the node browser specific " java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://localhost:4444/grid/register -port 5556 -browser "browserName=firefox,version=11.0,maxInstances=5,platform=WINDOWS" "

Invoked another node browser specific " java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://localhost:4444/grid/register -port 5557 -browser "browserName=iexplore,version=11.0,maxInstances=5,platform=WINDOWS" "

When you specify the browser flavors as above, you essentially are configuring your webdriver node to only support WebDriver mode (type=WebDriver) and no Selenium mode (type=Selenium) 

That is why you are seeing the Grid complain to you stating 

Caused by: com.thoughtworks.selenium.SeleniumException: org.openqa.grid.common.exception.GridException: Error forwarding the new session cannot find : {browserName=*iexplore}

Caused by: com.thoughtworks.selenium.SeleniumException: org.openqa.grid.common.exception.GridException: Error forwarding the new session cannot find : {browserName=*firefox}

You can cross check this by launching your hub console and doing a mouse move over on the browser icons. You will only see the browser name as "internet explorer" and "firefox" respectively.

Can you please just retry with using

java -jar selenium-server-standalone-2.20.0.jar -role node -hub http://localhost:4444/grid/register -port 5557

What this essentially gives you is :

5 FF instances, 5 chrome instances and 1 IE instance that supports both

WebDriver driver = new RemoteWebDriver() //WebDriver mode  and

DefaultSelenium selenium = new DefaultSelenium() //legacy Selenium mode.

If you would like to tweak the capabilities of the webdriver node when it is being spawned, you should really look at using node configuration JSON files.

Take a look at my post : http://rationaleemotions.wordpress.com/2012/01/23/setting-up-grid2-and-working-with-it/

Wherein I have tried to detail as much as I can on how you can start off your grid and webdriver nodes and also how to work with leveraging JSON node configuration files.

Thanks & Regards

Hi Krishnan

I was facing the simmilar problem but its resolved now, but the another problem is my rc test contains 69 suites, some of suites are missing in the test results, the result is something like below

 

MODULE	TOTAL	PASSED	FAILED	LINK
SETUP	9	0	9	link
SMOKE	56	0	56	link
Total	65	0	65

 

whereas  the total count should me 69. 4 smoke modules are missing. Can u give me a solution to this. I am using selenium version 2.35.0, firefox version 5.0, teamcity version 6.5.5

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

[Krishnan Mahadevan]

Why do you think this issue of yours is related to WebDriver/Selenium ?

I would suggest that you post a trimmed version of your query either in the JUnit or TestNG forums.

Thanks & Regards
