Like this?

def case_mulli(self):

    test_values = [-32768, -32767, -32766, -2, -1, 0, 1, 2, 32766, 32767]

    for i in range(20):
        test_values.append(random.randint(-1 << 15, (1 << 15)-1))

    l = ["mulli 3, 1, 2"]
    for ra in test_values:
        for rb in test_values:
            initial_regs = [0] * 32
            initial_regs[1] = ra
            initial_regs[2] = rb
            # use "with" so as to close the files used
            with Program(l, bigendian) as prog:
                self.add_case(prog, initial_regs)
