Overview of this book

This book is an incremental guide that will help you learn and use the advanced features of the Selenium toolset including the WebDriver API in various situations to build a reliable test automation. You start off by setting up the test development environment and gain tips on the advanced locater strategy and the effective use of the Selenium WebDriver API. After that, the use of design patterns such as data - driven tests and PageFactory are demonstrated. You will then be familiarised with extending Selenium WebDriver API by implementing custom tasks and setting up your own distributed environment to run tests in parallel for cross-browser testing. Finally, we give you some tips on integrating Selenium WebDriver with other popular tools and testing mobile applications. By the end of this book, you will have learned enough to solve complex testing issues on your own.

Finding elements using CSS selectors


The Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (the looks and formatting) of a document written in a markup language such as HTML or XML.

Major browsers implement CSS parsing engines to format or style the pages using CSS syntax. CSS was introduced to keep the presentation information separate from the markup or content. For more information on CSS and CSS selectors, visit http://en.wikipedia.org/wiki/Cascading_Style_Sheets.

In CSS, the pattern-matching rules determine which style should be applied to elements in the DOM. These patterns, called selectors, may range from simple element names to rich contextual patterns. If all conditions in the pattern are true for a certain element, the selector matches the element, and the browser applies the defined style in CSS syntax.

In this recipe, we will explore some basic CSS selectors and then, later on, we will dive into advanced CSS selectors.
