Test Excess Blob Gas¶
Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py@206854b5.
Generate fixtures for these test cases for Prague with:
fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py --fork Prague
Tests excessBlobGas and blobGasUsed block fields for EIP-4844: Shard Blob Transactions
Test excessBlobGas and blobGasUsed block fields for EIP-4844: Shard Blob Transactions.
Adding a new test
Add a function that is named test_<test_name> and takes at least the following arguments:
- blockchain_test
- env
- pre
- blocks
- post
- correct_excess_blob_gas
The following arguments need to be parametrized or the test will not be generated:
- new_blobs
All other pytest.fixture fixtures can be parametrized to generate new combinations and test
cases.
