Overview of this book

This book is an incremental guide that will help you learn and use the advanced features of the Selenium toolset including the WebDriver API in various situations to build a reliable test automation. You start off by setting up the test development environment and gain tips on the advanced locater strategy and the effective use of the Selenium WebDriver API. After that, the use of design patterns such as data - driven tests and PageFactory are demonstrated. You will then be familiarised with extending Selenium WebDriver API by implementing custom tasks and setting up your own distributed environment to run tests in parallel for cross-browser testing. Finally, we give you some tips on integrating Selenium WebDriver with other popular tools and testing mobile applications. By the end of this book, you will have learned enough to solve complex testing issues on your own.

Capturing screenshots of elements in the Selenium WebDriver


The TakesScreenshot interface captures the screenshot of the entire page, current window, visible portion of the page, or of the complete desktop window in their respective order as supported by the browser. It does not provide a way to capture an image of the specific element.

We can extend the screen capture functionality to capture images of WebElement using the Java Image API in addition to the TakesScreenshot interface.

In this recipe, we will implement a helper method to capture images of elements.

How to do it...

Let's implement the captureElementPicture() method to capture an image of WebElement. We will pass a WebElement instance to this method; the following code shows an example:

public static File captureElementPicture(WebElement element)
      throws Exception {

    // Get the WrapsDriver of the WebElement
    WrapsDriver wrapsDriver = (WrapsDriver) element;

    // Get the entire Screenshot from the driver of passed WebElement...
