Test Status Code Input and Output
1   Fail
x = []; y = []; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))

y = 'ERROR'

Index exceeds the number of array elements (0). Error in construct_string (line 14) if lengths(1)<0 Error in Test1 (line 3) assert(isequal(construct_string(x,y),y_correct))

2   Pass
x = [-1]; y = ['a']; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))

y = 'ERROR'

3   Fail
x = ['a']; y = [5]; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))

Output argument "y" (and maybe others) not assigned during call to "construct_string". Error in Test3 (line 3) assert(isequal(construct_string(x,y),y_correct))

4   Pass
r = 10+randi(20); x = [r 1]; y = 'ab'; y_correct(1:r) = 'a'; y_correct(r+1) = 'b'; assert(isequal(construct_string(x,y),y_correct))

5   Pass
x = [5 4 3 2 1]; y = '.#4a5'; y_correct = '.....####444aa5'; assert(isequal(construct_string(x,y),y_correct))
