Silverlight, Unit Testing and GUI testing

I have written MVC2 and MVC3 applications and used Unit Testing within Visual Studio 2008 and 2010.  If I want to use Unit Testing with a Silverlight app. and its associated Out of Browser app., must it be built with the MVC design pattern? If I do not use MVC, I presume the code that gets unit tested would be the Data Acces Layer, for example. Please explain this.

Also, how would I use Unit Testing to test the GUI work?

OK, you may find tens of opinions on unit testing. Probably :)

For me  - unit testing does not really depend on MVC or other technology or paradigm. According to Wikipedia, "... unit testing is a method by which individual units of source code are tested to determine if they are fit for use. A unit is the smallest testable part of an application." Usually a unit is a method. People may argue if we test private methods but still this does not change anything. We just write some code to test a validity of a method. One test normally represent just one scenario (one variation of passed args etc).

In normal unit testing it's required to avoid using a real database. Or any database at all (use mocking for DB results).

Testing databases and an access layer - a bit different. Not exactly unit testing for me. Anyway, try the link:

Oh, forgot about UI testing.

Not much I can say. But UI testing is very different from unit testing. And normally people do not unit test UI classes. They use something else.

For UI testing in our company we have an in-house system, and I don't really know much about other systems. However, a new frameworkwas introduced: NUnitForms. See
