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.
