Using Adobe Browser Lab & Adobe Shadow
Adobe BrowserLab is an online service that allows web professionals to test both publicly viewable and private web pages. Screenshots of actual browser renderings are generated in real time, with multiple viewing options and diagnostic tools to help discover cross-browser compatibility issues. BrowserLab is ideal for professional web designers and web developers who need to ensure their public and private web pages are viewed as they were intended on multiple browsers and operating systems.
BrowserLab renders screenshots virtually on demand with innovative viewing and diagnostic tools that fit seemliness into your work flows. BrowserLab can also preview local content through integration with Dreamweaver or Firebug. If you take the COAP 2120: Web Editors course will will get into using Browser Lab more within Dreamweaver. Also another tool that I will mention in this video similar to Browser Lab is Adobe Shadow which is geared more toward testing on mobile devices. I used to demo Device Central in this class but the project has been abandoned by Adobe and they are moving more toward Shadow.
