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.

Web developers can now create cool drawing applications within web browsers using the new HTML5 <canvas> element. This element is used to build drawing and charting applications by using JavaScript. Canvas has several methods for drawing paths, boxes, circles, characters, and adding images.

In this recipe, we will automate a simple drawing application through the Selenium WebDriver action class for mouse movements. We will also implement an image comparison feature to test the drawing on a canvas.

Internet Explorer 9+, Firefox, Opera, Chrome, and Safari support the <canvas> element.
