Mastering Selenium WebDriver 3.0 - Second Edition

Overview of this book

The second edition of Mastering Selenium 3.0 WebDriver starts by showing you how to build your own Selenium framework with Maven. You'll then look at how you can solve the difficult problems that you will undoubtedly come across as you start using Selenium in an enterprise environment and learn how to produce the right feedback when failing. Next, you’ll explore common exceptions that you will come across as you use Selenium, the root causes of these exceptions, and how to fix them. Along the way, you’ll use Advanced User Interactions APIs, running any JavaScript you need through Selenium; and learn how to quickly spin up a Selenium Grid using Docker containers. In the concluding chapters, you‘ll work through a series of scenarios that demonstrate how to extend Selenium to work with external libraries and applications so that you can be sure you are using the right tool for the job.

To do that, we are going to design DSL for our page objects that uses chains of commands to describe the action(s) that are being performed. Each chained command will return either a reference to itself, a reference to a new method, or a void. 

The LoginPage object that we created earlier in this chapter will provide a good base for a fluent page object. It currently looks like this:

package com.masteringselenium.query_page_objects;

import com.lazerycode.selenium.util.Query;
import com.masteringselenium.fluent_page_objects.BasePage;
import org.openqa.selenium.By;

public class LoginPage extends BasePage {

private Query usernameField = new Query(By.id("username"),
driver);
private Query...
