test_block_gas_limit_below_minimum()

Documentation for tests/frontier/validation/test_header.py::test_block_gas_limit_below_minimum@ffe48572.

Generate fixtures for these test cases for Bogota with:

fill -v tests/frontier/validation/test_header.py::test_block_gas_limit_below_minimum --fork Bogota

Tests that a block with a gas limit below the minimum throws an error.
