Execute test on Opera

The Problem
Just like any other browser except firefox, you need additional setup for OperaDriver too.

A Solution
Let's step through how to do it and make sure it's working.

An Example
The prebuilt OperaDriver executable can be downloaded from here (https://github.com/operasoftware/operaprestodriver/downloads). Download it, double-click it, and click Trust when prompted.

Now if we open up an interactive Ruby terminal (e.g., irb) and launch a Selenium instance, here's what we'd see.

> irb
irb(main):001:0> require 'selenium-webdriver'
irb(main):002:0> driver = Selenium::WebDriver.for :opera


A successful communication between Safari and the Selenium Driver extension has occurred.

Now let's wire up a simple test so we can see that everything works as expect.

# filename: ruby.rb

require 'selenium-webdriver'
require 'rspec/expectations'
include RSpec::Matchers

def setup
  opera_path = File.join(Dir.pwd, '..', '..',"vendor","operadriver")
  Selenium::WebDriver::Opera.driver_path = opera_path
  @driver = Selenium::WebDriver.for :opera
end

def teardown
  @driver.quit
end

def run
  setup
  yield
  teardown
end

run do
  @driver.get 'http://the-internet.herokuapp.com'
  expect(@driver.title).to eql 'The Internet'
end


Expected Behavior
When you save the file and run it (e.g., ruby safari.rb from the command-line), here is what will happen:

Opera opens
The home page of the-internet loads
The title of the page is checked to make sure it's what we expect
Opera closes


Happy Testing!
