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.

All that we are going to do is create a new <script> element in a page and then load our library into it. First of all, let's make sure we have access to a driver object in this class:

private RemoteWebDriver driver;
@BeforeMethod
public void setup() {
driver = getDriver();
}

Then we will need to add some code that will let us inject a <script> element:

private void injectScript(String scriptURL) {
driver.executeScript("function injectScript(url) {\n" +
