🐍 Cancun Devnet 8 + 4788 v2 Pre-Release

This pre-release updates all cancun tests according to Update EIP-4788: initial stab at v2, and the Devnet-8 Cancun specification, with a few considerations:

• Beacon root contract is pre-deployed at address 0x000000000000000000000000000000000000000b instead of the address described in the EIP PR
• No system transactions are executed for the generation of the fixtures and instead a direct storage update is performed at the beginning of the block

EIP-4844: Shard Blob Transactions
EIP-5656: MCOPY - Memory copying instruction
EIP-6780: SELFDESTRUCT only in same transaction

v1.0.0

🧪 Welcome to the PyTest Era

We are extremely happy to announce this major new release as it marks a huge milestone for execution-spec-tests.

With this release, adding tests has become easier than ever, so we invite and encourage all client developers to seize this opportunity and contribute to the continuous enhancement of the ethereum testing ecosystem.

🗝️ Key Changes

• Pytest takes the stage: Introducing the upgrade to pytest, now used to collect and execute tests, including generation of fixtures.
• Shiny new documentation: A full revamp of the docs which is now available at ethereum.github.io/execution-spec-tests.
• Tests by fork: Tests (previously named fillers) and fixtures, are now re-organized by fork name for improved clarity and usage.
• Commands with comfort: Tests are now filled with a new user friendly and readable CLI, including a new additional option to specify the solc binary.
• Write tests like a pro: the repo now includes recommended extensions & settings for a seamless new developer start.

Full Changelog: v0.2.5...v1.0.0

🐍 Tests

Updates to Existing Tests

• fixtures.tar.gz includes a refresh of previous State & Blockchain tests, up to and including Shanghai:
  • Each test has been refactored and now utilizes Pytest parameterization. These can be viewed within the test case reference section of the docs.

New EIP-4844 Tests

• fixtures-cancun.tar.gz includes a full set of Blockchain tests for EIP-4844, up to date with the latest Devnet 6 & 7 changes

🛠️ Usage

All tests can be filled with the new CLI using the fill command. (Note: tf is deprecated and will be removed in the next release).

By default fill generates fixtures for all tests up to the current mainnet fork - Shanghai. Detailed information on the new CLI can be found within the docs.

Generating EIP-4844 Tests

To only generate the new EIP-4844 tests the following command can be run:

fill -v tests/cancun --until=Cancun

Versions Used

Main fixtures: ethereum/go-ethereum @ c7b099b go-ethereum branch.

Cancun fixtures: marioevz/go-ethereum @ d36b63d go-ethereum branch.

Additional dependency versions used (others may work):

• Solidity @ 0.8.20
• Python @ 3.10.6

🐝 Pyspec Hive Simulator

Each EIP-4844 test case within fixtures-cancun.tar.gz can additionally be run within the updated pyspec hive simulator. It sends each block within a test fixture as a payload to the execution client using the Engine API.

v0.2.5

Tests

Cancun

• Separate fixtures to test for Cancun: includes the first version of the 4844 fixtures. (#63)
• These currently test for valid/invalid blob transactions, excess data gas calculations and the DATAHASH opcode.
• Additional tests for kzg pre-compiles and ssz will be added in a future release.
• Test documentation can be found -> here.
• These will be run within the hive pyspec simulator on this branch.

Important: These tests can only be filled using the geth version listed below, alongside the --latest-fork Cancun flag. As an example, you can run the 4844 tests with the following command: tf --force-refill --latest-fork Cancun --test-categories eips.eip4844.

Pre-Cancun

• New filler category added for security tests, used to verify previously identified client vulnerabilities. (#112)
• Access list test case example filler added. (#83)

Changes

• Reference spec feature added to fillers & fixtures. (#81)
• Fork object feature added to fillers. (#91)
  • Can now write tests for fork transitions.
• Callable Op-codes feature added reducing the dependency of Yul code (#102)
  • Most filler modules are now entirely python.
• Access list type support added. (#83)
• Documentation updated to include 4884 test descriptions -> here.

v0.2.4

Changes

• Additional checks added to the Tox pipeline. Python file and function names now checked in accordance with PEP8. (PR: #59)
• Naming style structure changed in the fixture format. withdrawals_ head removed from name of all withdrawals fixtures. Fixture test case names now like 000/shanghai instead of 000_shanghai. Tags added to specific test case names i.e. 001/multiple_blocks/shanghai. (PR: #69)
• Updates and additions to the test filler tf: (PRs: #66 & #72)
  • Refactor of ethereum_test_filling_tool.
  • Default tf execution is now concurrent/parallel. So far ~65% increase in speed which will scale as more tests are added.
  • Filling is skipped for tests that don't need to be filled by default. Improvement to tf execution speed.
  • tf --benchmark. Adds timing of filling to the console logs.
  • tf --max-workers. Allows the user to set the number of workers used for concurrent tf execution. For serial execution (the previous way) use tf --max-workers 1.
  • tf --force-refill. Force tests to be filled. Works with --test-module and --test-categories.
  • tf --no-output-structure. When enabled all tests are added to a single equivalent output folder.
