Selenium RC problem - forwarding error(?)

Hi,

heres my code and error that gives me everytime i try it to run.

It's some basic selenium test in java.

// I can't use links, but that code, what I have is @pastebin.com slash TiuDvQvK

I'm using selenium-standalone-server-2.16.1.

And i just don't know what to do with that error. When i do the same things on another compuer (runs server and try to run this test), it works. But not on my PC..
I was trying to google that, but with no effect..


Any sugestions, please?

Change this line

Code:

selenium = new DefaultSelenium("localhost", 4444, "*chrome", "http://www.google.cz/");

for

Code:

selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://www.google.cz/");

That only change error for this:

Code:

1) testPrvni(nanuk1.prvni)java.lang.RuntimeException: Could not start Selenium session: org%2Eopenqa%2Egrid%2Ecommon%2Eexception%2EGridException%3A+Error+forwarding+the+new+session+Empty+pool+of+VM+for+setup+%7BbrowserName%3D%2Afirefox%7D

I have installed both browser - chrome & firefox..

Probably it won't be in that.. Any other suggestions, please?

What operating system are you using?
See what happens when you remove this line:

Code:

selenium.start();

I'm using W7.

And now I same problem, trying to connect jenkins server running on my computer.

With this:

Code:

Selenium selenium = new DefaultSelenium("localhost", 4444, "*firefox", " h t t p : / /jenkins-ci.org/");
selenium.start();

Comes this error:

Code:

1) testPrvni(nanuk1.prvni)java.lang.RuntimeException: Could not start Selenium session: org%2Eopenqa%2Egrid%2Ecommon%2Eexception%2EGridException%3A+Error+forwarding+the+new+session+Empty+pool+of+VM+for+setup+%7BbrowserName%3D%2Afirefox%7D

Roman, please let us know more details.

When i do the same things on another compuer (runs server and try to run this test), it works.

You have Windows7 and selenium-standalone-server-2.16.1 on your PC, and what about the other computers in which you were tested? Are there also Win7 and the same version of Selenium?

Maybe you will try with lower version of Selenium Standalone Server (I am using 2.13.0)?

And one more question: how do you run the Selenium server? Have you were trying run it by command in console?

Code:

java -jar selenium-server-standalone-2.16.1.jar

No, on the other computer, where I tried that, there are is same version of selenium, but not of win. I have there a win xp.

I was starting the server just like you wrote, but with "-role hub" paramter.

Now I have runing Selenium Grid in Jenkins. But it's same like this. I think.

Code:



Registered Remote Controls

Selenium Grid is running at localhost:4444.
            Selenium 1 clients should connect as follows:
Selenium selenium = new DefaultSelenium("localhost", 4444, "*firefox", "htt p : / /jenkins-ci. org/");

With same effect.

So this is probably the fault of the operating system... I read that Window7 causes some problems in interacting with Selenium.
Have you any possibility for changing system? It would the simplest way to solve this problem...

Not right now, unfortunately. But I have now runing jenkins instance on my computer and adding tests to it SeleniumHQ htmlSuite run addon. That's close enough for me.

(it's working nice, only problem that I have is that firefox on my computer isn't working fine. It can't open. Usually I have to run test more times, to get my results. But that problem is for another forum, I guess...)

So thank you for help and your time.
