Test Blob Txs¶
Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py@49c766fb.
Generate fixtures for these test cases for Prague with:
fill -v tests/cancun/eip4844_blobs/test_blob_txs.py --fork Prague
Tests blob type transactions for EIP-4844: Shard Blob Transactions
Test blob type transactions 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 or state_test
- pre
- env
- block or txs
All other pytest.fixture fixtures can be parametrized to generate new combinations and test cases.
