So how exactly do you test that your SQL query does the right thing? That you're using the Twitter API correctly?

Testing a database, or an external web service, is an integration test. They can be as simple as:

    void TestCreateUser() {
        var repo = new UsersRepository();
        var mockUser = new User("John", "Smith");
        repo.AddUser(mockUser); // db call
        var addedUser = repo.GetUsers().Single(); // db call
        Assert.StructureIsEqual(mockUser, addedUser);
    }

For the Twitter web service, you might test that you successfully get a response, as you don't have control of what exactly comes back.
