test_gas_usage()

Documentation for tests/cancun/eip1153_tstore/test_tstorage.py::test_gas_usage@verkle@v0.0.6.

Generate fixtures for these test cases for Cancun with:

Cancun only:

fill -v tests/cancun/eip1153_tstore/test_tstorage.py::test_gas_usage --fork=Cancun --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Cancun:

fill -v tests/cancun/eip1153_tstore/test_tstorage.py::test_gas_usage --until=Cancun

Test that tstore and tload consume the expected gas.
