Re: Logging in selenium grid2 ?

[Mike Riley]

To what logs are you referring to?  The ones produced by the server, or logs produced by your test code (like TestNG reports)?

Hi Mike

Thanks for replying, I need the TestNg reports of the test scripts execution how do I do it using selenium grid2 can you help?

Hi Mike 

This is what I am doing

 I am using selenium grid2 to test my scripts and my problem is that I need to extract the log of the script that is executing on a particular node of the grid and for that I have written the following code

/* THIS CODE STARTS THE HUB AND ATTACHES A NODE TO THE HUB */

return node; }

}

/* THIS IS THE TEST SCRIPT WE EXECUTE THIS SCRIPT USING TESTNG WHICH SENDS A REQUEST ON TO THE HUB AND THE HUB ROUTES THE THIS SCRIPT TO A NODE THAT IS COMPATIBLE WITH THE CONFIGURATION SPECIFIED IN THE SCRIPT */

package com.qait.testrunner1;

import java.net.MalformedURLException; import java.net.URL;

import org.testng.annotations.*; import com.thoughtworks.selenium.DefaultSelenium; import com.thoughtworks.selenium.Selenium;

public class GridWithWebdriver {

public Selenium selenium;

@Parameters( { "browser" }) @BeforeClass public void setup(String browser) { selenium = new DefaultSelenium("localhost", 4444, browser,"http://google.com"); selenium.start(); }

@AfterClass public void tearDown() { selenium.stop(); }

@Test public void test_first() { selenium.open("/"); selenium.type("q", "First"); selenium.click("btnG"); }

@Test public void test_second() { selenium.open("/"); selenium.type("q", "second"); selenium.click("btnG"); }

}

Now the above script executes on the node of the selenium grid2 and I need to extract the logs of the script execution on the node.

We tried to use Logger to extract the logs of the nodes but what we get are the logs of the hub which is undesirable. Please suggest a way out for extracting the logs of the script executing on the node of the selenium grid. A sample code snippet will be really helpful

We referred this SO post -: How to get Test Activity Logs from Selenium Grid 2 programatically?

but in the above post the method requires a session-id attribute but we aren't able to retrieve the session id as we have made it a standalone system.

Thanks in advance

"All the desirable things in life are either illegal, expensive, fattening or in love with someone else!"

Have you tried WebDriver.getSessionId() and check if that works ? This method would yield the session id which is the webdriver's way of binding itself to a particular instance of a browser on a given node.

You would then couple this logic with this code snippet which basically tells you the IP and the port of the node to where your execution got routed to, by the grid. https://gist.github.com/1766772

Once you have both these information, you can do what has been suggested in the SO post which is basically do a JSON post on the grid's end-point to get all of the logs.

 

Thanks in advance

Hi Krishnan,

May be our approach is wrong.Actually what we want to do is as follows:-

We want to configure a selenium grid 2 hub and attach a node to it programatically through java as I showed you in our earlier conversation.

After this I run a script using testng.Now after running the test script on a particular node having selenium server,I want to get the result in the log of a particular node in the selenium grid. I would be highly grateful to you if you can point me to a full fledged example explaining this procedure or if you can suggest some particular sequence of steps that I need to do to accomplish this.

Thanks in advance

[Krishnan Mahadevan]

The information that I gave you still holds valid. Be it a Grid/node setup that gets spawned via code or separately using "java -jar" the approach to get hold of the sessionid is still the same, and if the Stack Overflow suggested approach is the way of extracting the logs, then you would need to pursue what I already highlighted (You basically need to put in the separate parts together to get it to work).

I haven't tried the approach as suggested in StackOverflow yet, so I wouldn't be able to comment on it.

Thanks & Regards

Hi Krishnan yet again could you please throw some light on the code given on the following link you suggested  https://gist.github.com/1766772  how did the user get the session id in the parameter of the function actually my problem is that we are  how do we call the function you mentioned by creating a RemoteWebDriver object manually, I am not able to understand how to call this function  

 private static String[] getHostNameAndPort(String hostName, int port,SessionId session) 

the only problem is how to pass this session id.

[Krishnan Mahadevan]

WebDriver driver = new RemoteWebDriver(URL, dc);

//We now would have been connected to a particular node by the grid.

String[] hostAndIP = getHostNameAndPort("localhost", driver.getSessionId());

This should do the trick.

I tried the code snippet given by you above but when I write driver.getSessionId() it shows that there is no such function for the object. What can we do to remedy this problem.

Thanks in advance

[Krishnan Mahadevan]

Silly me !! Am terribly sorry.

Try this :

RemoteWebDriver driver = new RemoteWebDriver(URL, dc);

//We now would have been connected to a particular node by the grid.

String[] hostAndIP = getHostNameAndPort("localhost", driver.getSessionId());

Hi Krishanan,

Thanks but we were able to resolve the above issue but now we are getting the following exception and I am not able to understand the reason:-

[15:14:33] suvigya17: Exception in thread "main" org.openqa.selenium.WebDriverException: org.openqa.grid.internal.GridException: Empty pool of VM for setup {platform=WINDOWS, seleniumProtocol=WebDriver, ensureCleanSession=true, browserName=internet explorer, version=}

Thanks and Regards,

[Krishnan Mahadevan]

That is because the Grid is only running but doesnt have any nodes at all. You would need to ensure that your code to spawn the node is also executed prior to you trying to get the IP and port of your node in question.

The same code has been running fine for me within my framework for quite sometime now. 

How are you starting the node and the hub ?

Hi Krishnan,

Actually I am starting the hub and node as follows:-

I downloaded the hub at the following location and from cmd I am executing the command as follows:-

C:\Documents and Settings\suvigya\My Documents\Downloads\selenium-grid-1.0.7-bin\selenium-grid-1.0.7>ant launch-hub

after this I executed the command for node in a new terminal as follows:-

C:\Documents and Settings\suvigya\My Documents\Downloads\selenium-grid-1.0.7-bin\selenium-grid-1.0.7>ant launch-remote-control -Denvironment="*iexplore"

and then I tried to run the code that I mentioned earlier.

Thanks,

You are using Grid1. The code snippet I shared with you works only for Grid2.

Grid1 stands DEPRECATED and is currently NOT being actively maintained. You should migrate over to Grid2 (which works in backward compatibility mode as well)

Please refer below links for understanding how to work with Grid2.

Ankit,

I would need to know what is in " at com.qait.testrunner1.GridInfoExtracter.main(GridInfoExtracter.java:30)"

Is it this line that is causing the problem for you ?

RemoteWebDriver webDriver=new RemoteWebDriver(url,DesiredCapabilities.internetExplorer());

If so, then its because your URL is incorrect.

You would need to change "URL url=new URL("http://localhost:4444/console");"

into "URL url = new URL("http://localhost:4444/wd/hub");

Hopefully that should resolve your issues.

Thanks & Regards
Krishnan Mahadevan

Ankit,

I think we already went over this error :

Exception in thread "main" org.openqa.selenium.WebDriverException: Error forwarding the new session Empty pool of VM for setup {platform=WINDOWS, browserName=*googlechrome}

This error comes up when you have just the grid running without any NODES hooked on to it.

Thanks & Regards

Oh I am really sorry krishnan,

Actually the exception is as follows:

I am able to understand the error but I am not able as to what changes i should make....

Please help me and really sorry to bother you.

[Krishnan Mahadevan]

The error is pretty straight forward

Exception in thread "main" org.openqa.selenium.WebDriverException: The driver executable is a directory: C:\Grid2\chromedriver_win_20.0.1133.0

WebDriver is telling you that the path to ChromeDriver.exe was not the exe file, but instead a directory.

I am really very grateful and thankful to you that you helped me so much to resolve this issue that I was stuck on since yesterday now I have got the session id and I need to get the logs of the node using this session id is there any method in the selenium grid 2 api that will accomplish this for me

Thanks

I have created a "Full fledged" working sample of how to get it done. Refer here : https://gist.github.com/3053517
