Issues, Questions in Selenium Grid2.0 C#

[Kaleem Uddin Mohammed Abdul]

The following are the issues which I'm facing
1. WebDriver.Quit() method throws below error when running test case using Selenium Grid. Whereas Driver.Close() works fine but I need to use Quit since my Test case will open multiple browser window.

17:25:16.620 INFO - Command failed to close cleanly. Destroying forcefully (v2).

java -jar selenium-server-standalone-2.46.0.jar -role node  -hub http://localhost:4444/grid/register -port 9999

But when I register the node using the below command which I got from google it works fine
C:\Kaleem\selenium-dotnet-2.46.0\SeleniumGrid>java -jar selenium-server-standalo
ne-2.46.0.jar -role node -port 9999 -hub http://localhost:4444/grid/register -br
owser "browserName=firefox,version=39.0,platform=WINDOWS,maxInstances=5"
Below is my C# code.
 public void RunRemotely()
        {
            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities = DesiredCapabilities.Firefox();
            capabilities.SetCapability(CapabilityType.BrowserName, "firefox");
            capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));
            capabilities.SetCapability(CapabilityType.Version, "39.0");

            _WebDriver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capabilities);
        }


3. I cannot see the 5 instance of FireFox running on my machine  when I set MaxInstance=5 but the log on Node is present. Is this expected?
java -jar selenium-server-standalo
ne-2.46.0.jar -role node -port 9999 -hub http://localhost:4444/grid/register -br
owser "browserName=firefox,version=39.0,platform=WINDOWS,maxInstances=5"

• For issue #1, the error states that it cant find the executable "taskkill". What OS is this ?
  

17:25:17.993 WARN - Exception thrown
java.lang.RuntimeException: Process refused to die after 10 seconds, and couldn't taskkill it: Unable to find executable for: taskkill

• For issue #2, its the Hub way of telling you that you asked for a node which could support Firefox browser running on WINDOWS platform with its version set as 39.0, but the Hub didnt find any nodes with this capability. You might want to take a look at this blog post of mine which talks about how to setup the Grid/node and work with it [ https://rationaleemotions.wordpress.com/2012/01/23/setting-up-grid2-and-working-with-it/ ]

• For issue #3, I didn't quite understand what the question was. So it would be good if you could rephrase your question/elaborate it.

Thanks Krishna for replying at the earliest. PFB my response to your questions.
Issue#1:


Issue#2.
I will try later and I don't see much difference except you are having these parameters in config file.
From these I came to conclusion that seleniumhq.org documentation needs to be updated.

Issue#3.
I mean to stay with my naked eye I can't see FireFox 5 instances running on my Machine but the Node Command Prompt has 5 instances of Firefox and each action in the test case is repeated 5 times.

Thanks,
Kaleem.

The errormessage you have posted talks about

"the webdriver.ie.driver system property"

Yet you are talking about google chrome.

You must have messed something up. Your test seems to be started with Internet Explorer as driver and that is why "the webdriver.ie.driver system" is being searched, not "the webdriver.chrome.driver system property". 

[Jim Evans]

Why are you bothering to override the browser name capability? DesiredCapabilities.Chrome gives you the proper browser name ("chrome", not "googlechrome") for the Chrome browser to be matched and executed in the grid.

[Kaleem Uddin Mohammed Abdul]

Thanks Jim! When I don't provide user defined name for browser name, the issue#4 doesn't exists more!

Can someone please update me on Issue#1 and Issue#3.

Thanks,
Kaleem.

What do you mean by issue #3? 

You mean that you set maxInstances to 5 but there is only 1 instance being created?

If so, that is most likely because of the node being in use by a session. Once a session is started on it, say a test that is executed in firefox, another session wont be started, thus another firefox-instance wont be opened. 

[Kaleem Uddin Mohammed Abdul]

If this is the case "

I would like to know, how could I open multiple instance of Browser and share my test cases across those Browsers.

Thanks,
Kaleem.

I can only suggest what i did and that was with JUNit.

Basically, ever test-method is instanced three times: Once for every browser that i specify.

However, every browser runs on his own Selenium-Grid node too. It's not like a single node tries to work with all three browsers at the same time.

That would not make sense to me and the Internet Explorer would have real issues with that, because it can not be ran with other browsers in parallel without having nativeEvents disabled.

Just to quickly explain it again:
Say i have class TestA with one testmethod called TestMethod1

When i run it, following happens:
TestMethod1 in FireFox gets send to my Grid-Server. The grid chooses a node to run it on and then the test runs.

TestMethod1 in Chrome gets send to my Grid-Server. The grid chooses a node to run it on and then the test runs.

TestMethod1 in InternetExplorer gets send to my Grid-Server. The grid chooses a node to run it on and the test runs. 

These all happen in Parallel, because i specified a Parallel and also Parametized runner.  So at that time, 3 Tests run in Parallel on 3 different nodes.

If there are more nodes available, then futher Test-Classes and TestMethods are executed in parallel. Otherwise the grid-server will make JUnit wait for an available node. 

Is that your question? 

[Kaleem Uddin Mohammed Abdul]

I was looking for the below
The following are the test cases
Test1
Test2
Test3
Test4
Test5
The following are the Browser instance
FireFoxInstance1
FireFoxInstance2
FireFoxInstance3
FireFoxInstance4
FireFoxInstance5

I would like to assign
FireFoxInstance1=Test1
FireFoxInstance2=Test2
FireFoxInstance3=Test3
FireFoxInstance4=Test4
FireFoxInstance5=Test5

As mentioned in my initial thread, I'm using C#.

http://nunit.org/index.php?p=parameterizedTests&r=2.5

I cannot give your more to work with nor does anyone else. This is purely specific to whatever testing framework that you use.

The link i suggested provides instructions for Nunit, which is a very common C# testing framework. 

If you are looking for parallized tests, then you could read through this thread: http://stackoverflow.com/questions/3313163/how-can-i-run-nunit-tests-in-parallel

Your question is really unclear and it is actually very hard to understand what you are asking in specific. 

Whatever you want, it's either related to a) the testing framework you use or b) your code management, how you pass driver-instances, how you use and share them among tests, etc.

But it infact does not have anything to do with Selenium.

[Kaleem Uddin Mohammed Abdul]

I'm not sure why my question was unclear.

Here, I am looking for distribution of test cases across many instances of a browser such that I can complete my test execution very fast.

My question was after reading the statement "This has two advantages. First, if you have a large test suite, or a slow-running test suite, you can boost its performance substantially by using Selenium Grid to divide your test suite to run different tests at the same time using those different machines. Also, if you must run your test suite on multiple environments you can have different remote machines supporting and running your tests in them at the same time. In each case Selenium Grid greatly improves the time it takes to run your suite by making use of parallel processing." of Selenium Grid which is mention @ http://docs.seleniumhq.org/docs/01_introducing_selenium.jsp

The following are the test cases
Test1
Test2
Test3
Test4
Test5
The following are the Browser instance
FireFoxInstance1
FireFoxInstance2
FireFoxInstance3
FireFoxInstance4
FireFoxInstance5

I would like to assign
FireFoxInstance1=Test1
FireFoxInstance2=Test2
FireFoxInstance3=Test3
FireFoxInstance4=Test4
FireFoxInstance5=Test5

So your question is clearly parallelism.

The link i provided in my previous post shows a beautiful SO thread which discussed all the possible options to achieve parallelism in a testing framework for C#.

That's all you need. Go read it, get into it and understand it. Parallelism is a little trick, at least it was for JUnit, but not really hard. You could implement this within a day. 

[Joerg Schmidt]

For issue #1:

For me it seems very strange to see something like:
 UnixProcess.destroy(UnixProcess.java:124)
in the Stacktrace when the process is running on Windows.

I see similar errors on my environment. The error disappears when i use older selenium java lib on the client side.

[Joerg Schmidt]

I did some debugging and i think the problem is that the running Selenium process finds taskkill.exe, but it is not allowed to execute it. ExecutableFinder.canExceute() does two checks.

1. it tests if the file is available
2. the it tests if the calling process is allowed to execute the file.

We execute our Selenium Tests as a Jenkins Job on a remote Build machine, the Jenkins slave was connected as an Webstart app which seems not to be allowed to execute taskkill.exe.
The Selenium Test was started a child process and it inherits the limitations of the webstart application.
Now we configured the build machine to do the connection to Jenkins with a local started java job and everything works fine.

[Krishnan Mahadevan]

The other reason why this happens is when as part of starting up the node you alter the PATH variable.

We ran into this blunder very recently and started seeing the same error message that "taskkill.exe was not to be found".

After digging around a lot, we realized our folly. Our batch file that is responsible for starting off the node, ended up overriding the PATH variable and appending some sub folders to it, but in the process we forgot to update the already assigned value of PATH via %PATH% to PATH so that we simulate the action of appending paths. What we had done was overwrite the PATH variable.(facepalm)
