Library (Tools) Reference Documentation

Execution spec tests consists of several packages that implement helper classes and tools that enable and simplify test case implementation. This section contains their reference documentation:

• execution_testing.base_types - provides the basic types on top of which other testing libraries are built.
• execution_testing.exceptions - provides definitions for exceptions used in all tests.
• execution_testing.fixtures - provides definitions of all test fixture types that are produced in this repository and can be consumed by clients.
• execution_testing.forks - provides definitions for supported forks used in tests.
• execution_testing.specs - provides definitions for all spec types used to define test cases, and generate different kinds of test fixtures.
• execution_testing.tools - provides primitives and helpers to test Ethereum execution clients.
• execution_testing.test_types - provides Ethereum types built on top of the base types which are used to define test cases and interact with other libraries.
• execution_testing.vm - provides definitions for the Ethereum Virtual Machine (EVM) as used to define bytecode in test cases.
• execution_testing.client_clis - a wrapper for the transition (t8n) tool.
• pytest_plugins - contains pytest customizations that provide additional functionality for generating test fixtures.
