Up to this point, all of the test code we've seen has just been demos and examples and we haven't actually run any tests. Let's set up the basic structure of our application so that we can start writing real tests.

The first thing to do is set up the folder structure that will house all of our tests. Within the root of the application project folder, create a folder named tests. Within the tests folder, create three more folders for controllers, models, and server:

/(existing app root)
tests/
----/controllers/
----/models/
----/server/

Writing a test helper

Create a file named testhelper.js within the tests folder and insert the following block of code:
