test_access_list_gas_cost()

Documentation for tests/amsterdam/eip7981_increase_access_list_cost/test_eip_mainnet.py::test_access_list_gas_cost@9c2813ee.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7981_increase_access_list_cost/test_eip_mainnet.py::test_access_list_gas_cost --fork Amsterdam

Test that transactions with access lists are charged correctly according to EIP-7981.

The test verifies that: 1. Access lists are charged for storage access (existing behavior) 2. Access lists are charged for their data footprint (new in EIP-7981) 3. Access list data contributes to the floor gas cost
