Overview of this book

Selenium WebDriver is a global leader in automated web testing. It empowers users to perform complex testing scenarios with its simple and powerful interface. This guide will provide you with all the skills you need to successfully create a functional Selenium test suite. Starting from the very beginning of the Selenium IDE, this book will show you how to transition into a real programing language such as Ruby or Java. You will quickly learn how to improve your code quality with refactoring and the skills needed to plan for the future development of your website to future-proof your test suite. With ample test examples running against a life-like e-commerce store and detailed step-by-step code review and explanations, you will be ready to test any challenge web developers might throw your way. This book is intended for anyone who wants to create a test suite that is easy to maintain by expanding your knowledge until you feel truly confident and comfortable with Selenium.

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can even open the search_test.html file in your web browser and see how it looks!"

A block of code is set as follows:

more_info_buttons = special_items.collect do |special_item|
  special_item.find_element(:class, "more-info")
end

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

require 'rubygems'
require 'selenium-webdriver'

selenium = Selenium::WebDriver.for(:firefox)
selenium.get("http://awful-valentine.com/")
selenium.find_element(:id, "searchinput").clear
selenium.find_element(:id, "searchinput").send_keys("cheese")
selenium.find_element(:id, "searchsubmit").click
selenium.quit

Any command-line input or output is written as follows:

ruby run_tests.rb

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on Install Now when it becomes clickable after several seconds."

Note

Warnings or important notes appear in a box like this.

Tip

Tips and tricks appear like this.
