Documentation for tests/cancun/eip4844_blobs/test_blobhash_opcode.py@49c766fb.
Generate fixtures for these test cases for Prague with:
fill -v tests/cancun/eip4844_blobs/test_blobhash_opcode.py --fork Prague
Tests BLOBHASH opcode in EIP-4844: Shard Blob Transactions
Test cases for the BLOBHASH opcode in
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
- pre
- tx
- post
Additional custom pytest.fixture fixtures can be added and parametrized for new test cases.
There is no specific structure to follow within this test module.
