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

Understanding the node

As our hub is up and running, it's now time to start a node and connect it to the hub. In this example, we will configure a macOS machine that has Chrome installed on it. So, if any test script requests the hub for a macOS platform and Chrome browser, the hub will choose this node. Let's see how we can start the node. The command to start the node and register with the hub is as follows:

java –jar selenium-server-standalone-3.12.0.jar –role node –hub http://192.168.0.101:1111/grid/register

This will start the Selenium server in the node mode and register this node with the already-started hub:

If you go back to the Grid Console on the browser, you will see the following:

The preceding screenshot shows the http://192.168.0.101:16784 node URL, which, in this case, is running on the Mac platform. By default, the number...
