“Hello World” - The TDD way?

Question

Well I have been thinking about this for a while, ever since I was introduced to TDD. Which would be the best way to build a \"Hello World\" application ? which would print \"H

Answer 1

Presenter-View? (model doesn't seem strictly necessary)

View would be a class that passes the output to the console (simple single-line methods)

Presenter is the interface that calls view.ShowText("Hello World"), you can test this by providing a stub view.

For productivity though, I'd just write the damn program :)

A single test should suffice (in pseudocode):

IView view = Stub();
Expect( view.ShowText("Hello World") );

Presenter p = new Presenter( view );
p.Show();

Assert.IsTrue( view.MethodsCalled );
