I work on the dev team of a complex web-based application which until recently was used exclusively by Windows users running IE.
As the app contains a lot of sophisticted JavaScript, DHTML and CSS we do a lot of testing on all different versions of Windows IE to make sure that it looks and works 100% as intended.
We recently rolled out the system to our first batch of Mac users who are running Safari v1.0.3 on OSX 10.2.8
Again we did a lot of testing on this platform to ensure everything worked.
So now I am wondering how many different versions of Safari I realistically need to be testing on going forward, as the new users could potentially upgrade their machines at any time.
Should I be testing on Safari v2 as well? How about the incremental versions in between? Are there really likely to be any differences between the Safari versions in terms of how JS/DHTML/CSS are implemented (as there are in IE)? Any advice/experiences you would care to share on this subject would be appreciated.
