test_beacon_root_contract_timestamps()

Documentation for tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_contract_timestamps@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_timestamps --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_timestamps --until=Cancun

Tests the beacon root contract call across for various valid and invalid timestamps.

The expected result is that the contract call will return the correct parent_beacon_block_root for a valid input timestamp and return the zero'd 32 bytes value for an invalid input timestamp.
