BrowserLab – fake crossbrowser tester from Adobe
Some time ago Adobe released interesting RIA application for cross browser testing - BrowserLab. From what I can see, basically - server (with some sort of capturing service in background) captures screenshot of your website in different browser engines (IE7, FF3 Win/OSX, Safari OSX) and then Flex application displays them side by side or in onion (overlay) mode for you to scroll or zoom in/out.
I have sincere doubts in usefulness of whole "crossbrowser debugging through overlayed screenshots" concept. Here is couple of reasons:
- you can only remotely suspect which dom element is causing problems, can't be for sure, you are watching screenshot after all
- long sites die in all browser screen captures (eg. nivas.hr is REALLY long and it's a good example of horridly long page which fails to be captured)
- show me one website which will correctly display in overlay mode in all engines BrowserLab supports, and I'll eat this post. :)
But off course, I am not xhtml guru, this is taken from programmers standpoint so maybe I am missing something crucial.
