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.

What are method signatures?

A method signature can be very simply defined as the method name followed by the parameter types. Say, for example, we have a method that adds two numbers. This is the method signature of this kind of method:

addNum(int, int)

The actual method is shown in the following code block. This method has to be invoked from another method or from the main() method, as in the following:

public int addNum(int num1, int num2) {
int result = num1 + num2;
return result;
Method call: addNum(10,20)
Output: 30

In the sections that follow, we will be looking at the method signatures of various important methods. But first, let's understand a concept of Java called List, which we will see in the findElements method.
