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 7

  1. Which argument can be used to specify how many browser instances can be supported by the node?

maxInstances.

  1. Explain how Selenium Grid can be used to support Cross Browser Testing.

With Selenium Grid, we can set up nodes for various Browser and Operating System combinations and run tests in a distributed architecture. Based on capabilities provided by the test, Selenium Grid selects the appropriate node and executes the test on the selected node. We can add as many nodes as required based on combinations we want to test as per the cross-browser testing matrix required for testing.

  1. What is the URL you need to specify with RemoteWebDriver to run tests on Selenium Grid?

http://gridHostnameOrIp:4444/wd/hub.

  1. Selenium Grid Hub acts as a load balancer: True or False?

True. Selenium Grid Hub distributes tests on multiple nodes based on the availability of the node
