Usage:
|
|
parity-evm state-test <file> [--json --std-json --only NAME --chain CHAIN]
|
|
parity-evm stats [options]
|
|
parity-evm stats-jsontests-vm <file>
|
|
parity-evm [options]
|
|
parity-evm [-h | --help]
|
|
|
|
Commands:
|
|
state-test Run a state test from a json file.
|
|
stats Execute EVM runtime code and return the statistics.

|
--input DATA Input data as hex (without 0x).
|
|
--gas GAS Supplied gas as hex (without 0x).
|
|
--gas-price WEI Supplied gas price as hex (without 0x).
|
|
|
|
State test options:
|
|
--only NAME Runs only a single test matching the name.
|
|
--chain CHAIN Run only tests from specific chain.
|
|
|
|
General options:
|
|
