function y = test_hasTeen();

% test_hasTeen runs several tests
% on the hasTeen function, displays hasTeen's
% output for each test, 
% and returns the number of tests that fail.

% Test by Adam Rosenbloom on 5-2-11
% On lines 52 to 53 the fprintf statement was proken up into two lines, I
% put the elipsis (...) that is necessary to break up the line in MATLAB...
% Apparently this must not be ecessary in Octave. Also added two test cases.
