SCENARIO


BACKGROUND 

One Saturday evening, on the 23rd of June,  Tom receives a call from his friend Mary from the university telling him that in two weeks' time, on Saturday July 7th 2012, there will be a reunion at the University celebrating their 15 years from graduation.

Mary informs him of the place and hour , at Aula (3rd floor, room 324) at 19.00, and offers to join him and help him navigate to the ceremony hall inside the university. Mary knows that Tom suffered the accident that caused him the loss of sight.
Tom refuses politely and says that he prefers testing the university's navigation system for visually impaired people.

 ACTIONS

Tom arrives by taxi (cab) at the University.
Tom finds the main entrance doors, opens them and enters the building.

He wonders whether there is an elevator. In case there is an elevator, he wants to know where the elevator is located in order to take it. Once he finds it, Tom calls the elevator to the ground floor. Once the elevator is arrived, he enters it and he starts searching for the button panel in order to figure out which button is adequate for the 3rd floor.
If there is no elevator in the building, then Tom wants to know where is the staircase located. Once he finds it, he starts climbing. At each floor, he wants to know whether he has arrived on the right floor or if he has to continue climbing the stairs.

Once he is arrived on the 3rd floor, Tom wants to know where is room 324 (the Aula). He walks on the hall and finally gets to the Aula.
There, he meets with his colleagues that were gathered in front of the Aula and start talking.
