Setup the Why Test? Example application:

• Download the source code for theCake Bar web application.
• Unzip the folder you just downloaded.
• Skip this step if you already have a MongoDB process running. If not, open a new command line session, and use the following command to start a new MongoDB instance.

$ mongod --dbpath ~/data/db

• Keep your current terminal session open and open a new terminal window. In your new terminal session, navigate to the Cake Bar directory that you unzipped. You can navigate to the Cake Bar directory by typingcdinto your command line, then dragging and dropping the Cake Bar folder from your finder.
• Runnpm installto download all of the required node packages for the Cake Bar application.
• From your command line, runnpm testto execute the Cake Bar test suite. After a few seconds you should see all of the tests pass in your terminal. (If you don’t see all tests passing, go toserver.config.jsand change8001to8000.)
• Runnpm startto start your server. When you see “listening on port 4001”, move to the next step.
• In your browser, visithttp://localhost:4001to see the Cake Bar application.
