Use: "check:construction",
Short: "Check the correctness of a Rosetta Construction API Implementation",
Long: `The check:construction command runs an automated test of a
Construction API implementation by creating and broadcasting transactions
on a blockchain. In short, this tool generates new addresses, requests
funds, constructs transactions, signs transactions, broadcasts transactions,
and confirms transactions land on-chain. At each phase, a series of tests
are run to ensure that intermediate representations are correct (i.e. does
an unsigned transaction return a superset of operations provided during
construction?).
Check out the https://github.com/coinbase/rosetta-cli/tree/master/examples
directory for examples of how to configure this test for Bitcoin and
Ethereum.
Right now, this tool only supports transfer testing (for both account-based
and UTXO-based blockchains). However, we plan to add support for testing
arbitrary scenarios (i.e. staking, governance).`,
