Test Point Evaluation Precompile

Documentation for tests/cancun/eip4844_blobs/[email protected].

Generate fixtures for these test cases for Osaka with:

fill -v tests/cancun/eip4844_blobs/test_point_evaluation_precompile.py --fork Osaka

Tests point evaluation precompile for EIP-4844: Shard Blob Transactions.

Note: Adding a new test Add a function that is named test_<test_name> and takes at least the following arguments.

Required arguments: - blockchain_test or state_test - pre - tx - post

The following arguments need to be parametrized or the test will not be generated:

• versioned_hash
• kzg_commitment
• z
• y
• kzg_proof
• result

These values correspond to a single call of the precompile, and result refers to whether the call should succeed or fail.

All other pytest.fixture fixtures can be parametrized to generate new combinations and test cases.
