  """Test the importmulti RPC.
  
  Test importmulti by generating keys on node0, importing the scriptPubKeys and
  addresses on node1 and then testing the address info for the different address
  variants.
  
  - `get_key()` and `get_multisig()` are called to generate keys on node0 and
    return the privkeys, pubkeys and all variants of scriptPubKey and address.
  - `test_importmulti()` is called to send an importmulti call to node1, test
    success, and (if unsuccessful) test the error code and error message returned.
  - `test_address()` is called to call getaddressinfo for an address on node1
    and test the values returned."""
