  # Most SlotMachineInstructionTests test the risc instructions of the slot instruction
  # quite carefully, ie every instruction, every register.
  #
  # This is done with the assert methods in risc_assert
  #
  # Most tests go through instructions from top to bottom.
  # For working code, one can get a list of those instructions by using the all_str as message
  # Most tests will test for length and give the all_str as message to see where it went wrong
  # like: assert_equal 8 , all.length , all_str
