I had the impression that Watin was no longer being maintained and asked to which framework would be the best to switch to for testing of a website in a browser from .net?
Back in July on the WatiN mailing list, Jeroen stated the following.
...is WatiN still alive: Yes. Is the activity visible for the outside world: No, which is a bad thing.
During my holiday last two weeks I have been thinking about how to proceed and decided that I will work on WatiN every Thursday evening. Number one prio is get the updated FireFox support and IE improvements out asap.
.
If moving away from WatiN, then Selenium 2 or later would be my first choice for a framework. Coded UI would be next. I've been part of a testing exercise where in the room WatiN, Selenium and Coded UI were all used to test the same site; the resulting structure was oddly similar across all three. Selenium seemed to have the best support for multiple browsers.
