"""Test the importdescriptors RPC.

Test importdescriptors by generating keys on node0, importing the corresponding
descriptors on node1 and then testing the address info for the different address
variants.

- `get_generate_key()` is called to generate keys and return the privkeys,
  pubkeys and all variants of scriptPubKey and address.
- `test_importdesc()` is called to send an importdescriptors 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."""
