Selenium WebDriver Quick Start Guide

By: Pinakin Chaubal

Overview of this book

Selenium WebDriver is a platform-independent API for automating the testing of both browser and mobile applications. It is also a core technology in many other browser automation tools, APIs, and frameworks. This book will guide you through the WebDriver APIs that are used in automation tests. Chapter by chapter, we will construct the building blocks of a page object model framework as you learn about the required Java and Selenium methods and terminology. The book starts with an introduction to the same-origin policy, cross-site scripting dangers, and the Document Object Model (DOM). Moving ahead, we'll learn about XPath, which allows us to select items on a page, and how to design a customized XPath. After that, we will be creating singleton patterns and drivers. Then you will learn about synchronization and handling pop-up windows. You will see how to create a factory for browsers and understand command design patterns applicable to this area. At the end of the book, we tie all this together by creating a framework and implementing multi-browser testing with Selenium Grid.

Unconditional synchronization

In most of the examples that we have looked at so far, we have made use of Thread.sleep(long); to wait for an element. Someone who is new to Java might wonder what a thread is. Let's first learn about the concept of a thread.

A thread is a single sequence of execution in a program. A particular program always runs on one thread, which is called the main thread. Another type of thread is one that is started from the main thread explicitly, and is called the child thread. In all the programs that we have seen so far, the execution was done on the main thread.


Let's look at the first type of unconditional synchronization, Thread.sleep.

The signature of the sleep(long...
