We'll give an overview of Ethereum Execution Spec Tests (EEST), the new Python framework used since Shanghai to generate test vectors for Ethereum Virtual Machine (EVM) implementations. By generating tests programmatically this modular framework allows test cases to be readily parametrized and dynamically executed against clients on live networks. It tightly integrates with the Ethereum Execution Layer Specification (EELS) and could potentially be used across the L2 EVM ecosystem.
