Error installing Nokogiri in Ubuntu 10.10

Following Nokogiri Installation for Ubuntu I run below #nokogiri requirement in my terminal:

sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri

Running “sudo gem install nokogiri” displays the following error:

Building native extensions.  This could take a while...
 ERROR:  Error installing nokogiri:

Was able to resolve the issue by installing ruby1.8-dev and reinstalling the nokogiri gem:

sudo apt-get install ruby1.8-dev 
sudo gem install nokogiri

Resolving “Couldn’t open app window; is the pop-up blocker enabled?” Selenium error in IE 10

Need to setup my Linux machine(master) to remotely access a Windows 8 machine(slave) with Internet Exporer 10 browser that will run my Selenium scripts.

master – machine where Selenium scripts, browser configurations are saved; one that will be sending requests to run the scripts

slave – machine where Selenium scripts will be run using a different platform (OS and browser); one that will accept the request to run the scripts

To do this, I configure the browser file from the master machine:

# for Internet Explorer
our $sel = Test::WWW::Selenium->new( host => "Windows Machine IP", port => 4445, browser => "*iexplore", browser_url => "application URL" );

From the slave machine, I needed to install the following:

- Java SE Runtime  Environment 1.7

- download latest Selenium Server from SeleniumHQ

To prepare the slave machine to accept the request, launch selenium server from the terminal using the same port set in the master machine:

java -jar selenium-server-standalone-2.23.1 -port 4445

To send request from the master machine, you may use “spec”, “rake” command depending on how you organized your test files. However after executing the command to run the scripts from the master machine, an error was encountered in the slave machine - “Couldn’t open app window; is the pop-up blocker enabled?”

IE 10 – Selenium error

Solution:

From the master machine, update browser configuration from “*iexplore” to “iexploreproxy”

# for Internet Explorer
our $sel = Test::WWW::Selenium->new( host => "Windows Machine IP", port => 4445, browser => "*iexploreproxy", browser_url => "application URL" );
