Parking garage automation uses a website and a mobile android application to place reservations in the parking garage.  To run unit testing, access the website at wwww.reserve-your-spot.com   
From here, an account needs to be registered to place a reservation.  After logging in with an email and password, click the "Place A Reservation" tab.  Next, choose the date and time for the reservation. Once this is done, the reservation can be seen from the "Reservation" tab and the spot can be viewed by clicking on the "View Garage" tab.  Similarly, though not fully implemented, tne mobile app will work this way. 

The unit testing will primarily involve trying to access certain parts of the websites without having the assigned priveleges and/or placing requests that aren't valid.  For now the site only serves to carry out the basic functions and not account for possible errors so there are several issues that can be exploited.  Another aspect of the site that needs to be looked at are the possibility of MySQL injections.  This is when the user can place a database query via the text boxes located on the web site.  There is no set code to test all the aspects of the web site at once and testing will primarily concern trying to run multiple requests online from end to end.
