test_beacon_root_contract_calls()

Documentation for tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_contract_calls@verkle@v0.0.6.

Generate fixtures for these test cases for Cancun with:

Cancun only: 

fill -v tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_contract_calls --fork=Cancun --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Cancun: 

fill -v tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_contract_calls --until=Cancun

Tests the beacon root contract call using various call contexts: - CALL - DELEGATECALL - CALLCODE - STATICCALL for different call gas amounts: - exact gas (valid call) - extra gas (valid call) - insufficient gas (invalid call)

The expected result is that the contract call will be executed if the gas amount is met and return the correctparent_beacon_block_root. Otherwise the call will be invalid, and not be executed. This is highlighted within storage by storing the return value of each call context.
