Re: Using WWW::Selenium To Test Or Automate An Ajax Website

in reply to Using WWW::Selenium To Test Or Automate An Ajax Website

I think I may have the same port 4444 problem with some code I tried to write to learn how to use Selenium. Basically I tried to write a perl program on Ubuntu to automate the entry of cokezone codes on the www.cokezone.co.uk website. From my terminal I got the following results:

icleave@icleave:~/Desktop/CokeZone$ perl cokezone.pl Error requesting http://localhost:4444/selenium-server/driver/?cmd=get +NewBrowserSession&1=*chrome&2=http%3A%2F%2Fwww.cokezone.co.uk%2F: 500 Can't connect to localhost:4444 (connect: Connection refused) # Looks like your test exited with 111 before it could output anything +.
What advice do you have for sorting this out on Ubuntu? Many thanks, Icleave

    icleave,
    Are you running the Selenium core? You need to have Selenium running before you can use the Selenium Remote-Control (driven by WWW::Selenium. It should be along the lines of (from memory and likely off a bit):
    java --jar selenium-core.jar

    You can verify that you have something listening on port 4444 by doing a netstat -an | grep LISTEN | grep 4444. If you don't see anything then you haven't properly started Selenium.

    Cheers - L~R

      Ty Limbic~Region for the post. I wasn't aware I needed to run the Selenium core. I did try running $netstat -an | grep LISTEN | grep 4444 and it didn't do anything so I figured I really didn't have the Selenium core.

      I tried running the $java --jar selenium-core.jar suggestion from my terminal but I got the following error:

      Unrecognized option: --jar Could not create the Java virtual machine.
      I guessed you meant "-jar" rather than "--jar" so I retyped the command at the terminal but I got the following:

      The program 'java' can be found in the following packages: * gij-4.3 * java-gcj-compat-headless * openjdk-6-jre-headless * cacao * gij-4.2 * jamvm * kaffe Try: sudo apt-get install <selected package> bash: java: command not found

      So I tired "sudo apt-get selenium-core" hoping this would work but it didn't. So the next thing I did was try searching the Synaptic Package Manager with no luck. I then googled and found http://release.seleniumhq.org/selenium-core/1.0.1/selenium-core-1.0.1.zip. I downloaded it and extracted but I couldn't make heads or tails of what to do next after reading the 'install-readme.txt.'

      Any advice on how I actually install Selenium core on Ubuntu? All my other searches for information on this didn't result in anything I could use.

      Also assuming that I get Selenium core running, is there any code I need to know about to "start" the Selenium core? I can't remember where I read it, but I read that you need the following code in your perl program:

      $sel->start();

      If so, where do I put it? I put it in my program here:

      my $sel = Test::WWW::Selenium->new( host => "localhost", port => 4444, browser => "*chrome", browser_url => "http://www.example +.com/" ); $sel->start(); $sel->open("/home/index.jsp");

      Did I get this code position correct?

      Many thanks for the help!

        icleave,

        There really isn't anything to install. You just download the jar files and run them. Looking at the error message you got, I would guess you don't have Java installed. You need to install Java to run Selenium. WWW::Selenium is a perl interface to Selenium Remote Control only.

        Did I get this code position correct?

        Yes. You should always check the SYNOPSIS in TFM which shows you the typical usage.

        Cheers - L~R

      Nowadays, it is (apparently) recommended to use Selenium RC server instead — Selenium Core is no longer maintained. You can download it from http://seleniumhq.org/download/.

      To run it, do

      java -jar selenium-server.jar

      Make sure to use a recent enough version of Java, it fails here with java 1.4.2 but it works with 1.6.0.
