Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_correct_excess_blob_gas_calculation@892e6d1e.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_correct_excess_blob_gas_calculation --fork Amsterdam

Test calculation of the excessBlobGas increase/decrease across multiple blocks with and without blobs.

• With parent block containing [0, MAX_BLOBS_PER_BLOCK] blobs

• With parent block containing [0, TARGET_BLOBS_PER_BLOCK] equivalent value of excess blob gas
