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

Chapter 3

  1. Which are the different formats we can use to output a screenshot?

The OutputType interface support screenshot types in BASE64, BYTES, and FILE formats.

  1. How can we switch to another browser tab with Selenium?

We can switch to another browser tab using the driver.switchTo().window() method.

  1. True or false: The defaultContent() method will switch to the previously selected frame.

False. The defaultContent() method will switch to the page.

  1. What navigation methods are available with Selenium?

The Navigate interface provides to() , back()forward() , and refresh() methods.

  1. How can we add a cookie using Selenium?

We can add a cookie using the driver.manage().addCookie(Cookie cookie) method.

  1. Explain the difference between an implicit wait and an explicit wait.

An implicit wait once set will be available for the entire life of the WebDriver instance. It will wait for the element when findElement is called for the set duration. If the element doesn't appear in DOM in a set time, it will throw the NoSuchElementFound exception.

An explicit wait, on the other hand, is used to wait for the specific condition to happen (for example, the visibility or invisibility of the element, a change in title, a change in attribute of the element, thee element becoming editable or for a custom condition). Unlike an implicit wait, the explicit wait will poll the DOM for the condition to fulfill instead of waiting for a fixed amount of time. It will come out if the condition is fulfilled before the defined timeout, else it will throw an exception. We can use various predefined conditions from the   ExpectedConditions class with the explicit wait.
