Witam!

Mam problem z odpaleniem najprostszego testu selenium (narzędzie instalowane typowo: “gem install Selenium selenium-client”):

[code=ruby]require ‘spec_helper’

describe “Untitled” do
attr_reader :selenium_driver
alias :page :selenium_driver

before(:all) do
@verification_errors = []
@selenium_driver = Selenium::Client::Driver.new
:host => “localhost”,
:port => 4444,
:browser => “*firefox”,
:url => “http://localhost:3001/”,
:timeout_in_second => 60
end

before(:each) do
@selenium_driver.start_new_browser_session
end

append_after(:each) do
@selenium_driver.close_current_browser_session
@verification_errors.should == []
end

it “test_untitled” do
true.should be_true
end
end[/code]
spec_helper.rb:

code=ruby gem “selenium-client”
require “selenium/client”
require “selenium/rspec/spec_helper” (…)[/code]
