TODO:

Refactor built transactions for with_all_tx_types into something that can be more useful across the board. I'm thinking default transactions that each fork can define if it includes a new tx type and tests can automatically use these transactions, override them as fixtures, or some other more useful flow than re-building every time.
- This was done via with_all_typed_transactions indirect (new feature) marker

✅ Checklist

All: Ran fast tox checks to avoid unnecessary CI fails, see also Code Standards and Enabling Pre-commit Checks:
```
uvx --with=tox-uv tox -e lint,typecheck,spellcheck,markdownlint
```
All: PR title adheres to the repo standard - it will be used as the squash commit message and should start type(scope):.
All: Considered adding an entry to CHANGELOG.md.
All: Considered updating the online docs in the ./docs/ directory.
All: Set appropriate labels for the changes (only maintainers can apply labels).
Tests: Ran mkdocs serve locally and verified the auto-generated docs for new tests in the Test Case Reference are correctly formatted.
Tests: For PRs implementing a missed test case, update the post-mortem document to add an entry the list.

Hmm having a difficult time reproducing this CI error locally. I added the concept of a @with_all_typed_transactions as a fixture that uses the tx_type covariant with fork to build default transactions. I successfully implemented this in the test that I wanted for testing the rlp block size limit. Each default transaction can be overridden if desired with:

@pytest.fixture
def type_2_default_transaction(sender):
    return Transaction(...)

Something in the stdout is being changed and ironically I am on a macos and I pass this test locally but the CI does not. I will keep looking into this but it would be nice to get a review here on the implementation and if anyone has an idea of what's causing this error, lmk.

Awesome! Thanks for implementing this.

I wrote a couple of comments that might be worth considering.

src/pytest_plugins/forks/transaction_fixtures.py

tests/osaka/eip7934_block_rlp_limit/test_max_block_rlp_size.py

- Move default transaction logic to a ``conftest.py`` setup. - Add ``conftest.py`` files for each fork with the respective transaction pytest fixtures. - Opt for `Type | None` over `Optional[Type]` to avoid an extra import.

I'm just missing the documentation here which I can update but we should get consensus on the code first and then I can document the changes appropriately and add the release notes.

- Move default transaction logic to a ``conftest.py`` setup. - Add ``conftest.py`` files for each fork with the respective transaction pytest fixtures. - Opt for `Type | None` over `Optional[Type]` to avoid an extra import.

- Move transaction fixtures to a `shared` pytest plugin. - Opt for `Type | None` over `Optional[Type]` to avoid an extra import. Bonus: - Refactor the `indirect` marker logic to be more generic for future use. If a marker uses `indirect`, it will take the values from the `fork_attribute_name` and run it through a fixture of name `argnames` which provides some added logic. In this case it builds default transactions from the `tx_types` values for each fork.

Awesome work, it's a very nice solution and thanks for removing the sender from the tests, it's a nice code reduction in general :)

I pushed a small change to fix the imports in the pytest .ini files, basically, anything that imported pytest_plugins.shared.execute_fill should also have transaction_fixtures.

Will merge after CI passes!

Ah, yeah, thanks for that cleanup! Do you want me to add any documentation around it? It was also missing a release note because we hadn't agreed yet on the path but I can add one before merge, lmk.

Yeah I guess it would be nice to have some docs in https://github.com/ethereum/execution-spec-tests/blob/main/docs/writing_tests/test_markers.md#pytestmarkwith_all_tx_types, thanks!

@pytest

- Create global fixtures for default transactions that are covariant with ``fork`` - These should allow overriding particular default transactions by re-defining the fixture for the particular tx type e.g.: ```python @pytest.fixture def type_2_default_transaction(pre): return Transaction(...) ``` - Use these as part of the ``fork`` plugin
