The testing framework should be imported explicitly
The second argument has the form [[x], [y], [z]] instead of [x, y, z] as stated by the description (the latter is wrong)
^ The same issue is true for the function output
No fixed tests
Duplicate (considering your solution performs multiplication for matrices of arbitrary size, I don't understand what's the point of this kata at all - to make a kata about matrix multiplication that is not 100% copy of the existing ones? looking at your completed katas list, I can see that you haven't done any of the existing matrix multiplication katas, so you've added this restriction just for the sake of it?)
