Add Dan from EF Testing

[marioevz]

Name

Dan, aka danceratopz.

Team

Testing Team @ Ethereum Foundation

Short summary of their work / eligibility

Dan became a part of the EF testing team in April, 2023. He has gained expertise in execution client testing and is an active maintainer of the relatively new execution-spec-tests repo.

Dan's main focus since starting has been the execution-spec-tests framework which generates test fixtures for execution clients focusing on upcoming protocol changes. This work includes a re-write of the framework test runner to use a standard Python test framework (pytest) that allows parametrization of tests, better test reporting and easier execution.

Link to some work

Code

• Maintainer of execution-spec-tests:
  • Use pytest as a test runner:
    • Proposal.
    • execution-spec-tests#116 - feature: use pytest to collect and execute test fillers.
  • Cancun testing:
    • EIP-1153 test cases (partially ported from ethereum/tests):
      • execution-spec-tests#230 - EIP-1153 Transient Storage Tests
      • execution-spec-tests#292 - tests: add more transient storage/eip-1153 tests
      • Test Case Reference doc / Re-entrancy test cases.
  • Added/helped add support for the Besu, Evmone, execution-specs and Nimbus transition tools.
  • Revamped doc pages, which include an automatically generated lists of parametrized test cases per EIP versioned by execution-spec-tests release.

Talks

• Co-presenting execution-spec-tests in ACD execution layer meeting 164: https://notes.ethereum.org/@danceratopz/execution-spec-tests-overview-202306

In progress / Planned

Currently working on:

• Executing blocktest to verify fixtures:
  • execution-spec-tests#325 - feat(fw): run evm blocktest on generated fixtures
  • execution-spec-tests#331 - feat(pytest): add option to write one fixture per json file

Planned:

• Enable configuration/execution of multiple t8n tools to allow test fixture generation from different EVM implementations with various features under development.
• Allow easy testing of EELS-implemented EIPs within execution-spec-tests.
• Hive.

Start date of relevant projects

Proposed weight (full or partial)

Full*

*Dan usually works 4 out of 5 days a week but he should still be considered full weight in my opinion, though it is worth mentioning since there is no 80% weight.

I have worked with Dan a bit and can attest to his substantial contributions to our testing work.

I work with Dan within the testing team alongside Mario (personally I have learned so much working with him).

The current state of EF Testing can be attributed largely to his efforts from his amazing improvements to execution-spec-tests.
