"""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."""
