test_warm_coinbase_gas_usage()

Documentation for tests/shanghai/eip3651_warm_coinbase/test_warm_coinbase.py::test_warm_coinbase_gas_usage@verkle@v0.0.6.

Generate fixtures for these test cases for Berlin with:

Berlin only:

fill -v tests/shanghai/eip3651_warm_coinbase/test_warm_coinbase.py::test_warm_coinbase_gas_usage --fork=Berlin --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Berlin:

fill -v tests/shanghai/eip3651_warm_coinbase/test_warm_coinbase.py::test_warm_coinbase_gas_usage --until=Berlin

Test the gas usage of opcodes affected by assuming a warm coinbase:

• EXTCODESIZE
• EXTCODECOPY
• EXTCODEHASH
• BALANCE
• CALL
• CALLCODE
• DELEGATECALL
• STATICCALL
