Testability in .Net

Your environment can have a profound effect on how you develop software. The details of what I discuss here have zero practical meaning outside of the .Net world (though you can probably find parallels in other environments). That’s because .Net developers have access to tools that invalidate rules of software design that are fundamentally important elsewhere (before you question whether an environment can effect what is good design, consider the difference between good design in C and, say, Prolog). For .Net, the free availability of a tool like Typemock makes a major design consideration simply disappear—namely, testability. Typemock literally robs the term “testability” of meaning in .Net design considerations. That’s a freedom that should leave other developers gasping in envy.
