I like to think of myself as a polyglot programmer and I can't help but disagree with your statement that ASP.NET MVC only looks good because Webforms is so horrible.

1. I am not sure why you have problems testing the wrapper classes. I can't say I've encountered issues unit testing my controllers or other MVC specific components.

2. You test the attributes themselves as you would test any other class. Eg you test that OnActionExecuting etc yield the correct results. On your controller, you just need to test for the presence of the attribute, since you already know that it works as advertised.

3. I cannot comment on your claim about the Layout system, but I have absolutely no idea what you mean with the 'having to hint the view engine'. You need to tell it which parts are inline code, and those parts should be C#. Razor has no interest in your JavaScript code.

4 and 5, again, can't comment on these since I haven't encountered them, even though I worked on a number of sites that had moments of extreme high load. In addition, I have found that the number of 'stuff that just breaks' is minor compared to what I've seen in other frameworks. Sometimes things go wrong, but it really is not as dire as you portray it.

My 2 cents, YMMV.
