Now that you probably have a good grasp on the basics of unit testing, you probably want to see some examples that put all of this knowledge together. This chapter will do just that; I built a little simple ASP.NET MVC 3 application that allows us to withdraw money from an account, deposit money on an account and transfer money to another account. I kept everything very simple, ignoring lots of best-practices to keep the unit testing as easy as possible. More...

Now that you know what test-first means and how you can build a testable architecture, you are ready to start writing some real unit tests. This chapter will explain what kind of assertions you have, how a good unit test is set up and more. More...

In order to be able to test your software without applying many dirty hacks, you have to embrace a couple of architectural patterns that allow you to isolate the pieces of code that you want to test.
