the future of web app testing and how to stop it
DESCRIPTION
Jason Huggins' presentation at JavaScript Chicago on 28 May 2009. The talk's titled "The Future of Web App Testing and How to Stop It" The first part was a brief history of the Selenium project. The second part was talking about the canvas tag and canvas based apps. The punchline is that canvas-tag based apps are untestable using traditional DOM-based introspection techniques. Developers need to be aware to make their canvas-based apps testable in their designs. And yes, canvas is the future of the web, and therefore the future of web testing.TRANSCRIPT
