Overview of this book

Selenium WebDriver 3.x is an open source API for testing both browser and mobile applications. With the help of this book, you can build a solid foundation and learn to easily perform end-to-end testing on web and mobile browsers. You'll begin by focusing on the Selenium Page Object Model for software development. You'll architect your own framework with a scalable driver class, Java utility classes, and support for third-party tools and plugins. Next, you'll design and build a Selenium Grid from scratch to enable the framework to scale and support different browsers, mobile devices, and platforms. You'll also strategize and handle a rich web UI using the advanced WebDriver API, and learn techniques to tackle real-time challenges in WebDriver. Later chapters will guide you through performing different types of testing, such as cross-browser testing, load testing, and mobile testing. Finally, you will be introduced to data-driven testing, using TestNG to create your own automation framework. By the end of this Learning Path, you'll be able to design your own automation testing framework and perform data-driven testing with Selenium WebDriver. This Learning Path includes content from the following Packt books: • Selenium WebDriver 3 Practical Guide - Second Edition by Unmesh Gundecha • Selenium Framework Design in Data-Driven Testing by Carl Cocchiaro

Taking screenshots

Taking a screenshot of a web page is a very useful capability of WebDriver. This is very handy when your test case fails, and you want to see the state of the application when the test case failed. The TakesScreenShot interface in the WebDriver library is implemented by all of the different variants of WebDriver, such as Firefox Driver, Internet Explorer Driver, Chrome Driver, and so on. 

The TakesScreenShot capability is enabled in all of the browsers by default. Because this is a read-only capability, a user cannot toggle it. Before we see a code example that uses this capability, we should look at an important method of the TakesScreenShot interface—getScreenshotAs().

The API syntax for getScreenshotAs() is as follows:

public X getScreenshotAs(OutputType target)

Here, OutputType is another interface of the WebDriver library. We can...
