You have

  xtest assert(bitshift(uint8(0:15),1),uint8(3),uint8([0 2 4 6 0 2 4 6 0 2 4 6 
0 2 4 6]))

Adding some whitespace so I can see what is going on, this is

  assert (bitshift (uint8 (0:15), 1),
          uint8 (3),
          uint8 ([0 2 4 6 0 2 4 6 0 2 4 6 0 2 4 6]))

Did you really mean

  assert (bitshift (uint8 (0:15), 1, uint8 (3)),
          uint8 ([0 2 4 6 0 2 4 6 0 2 4 6 0 2 4 6]))

?  If so, then I think Octave also passes this test.
