Working with module_globals

So i tried to inject some fixtures as "module_globals" into my doctests, but I can't seem to get it to work.

I've tried the following:

from pathlib import Path

import pytest
from pytest_examples import CodeExample, EvalExample, find_examples

DOCS_DIR = Path(__file__).parent.parent / "docs"
DOCS_FILES = DOCS_DIR.glob("**/*.md")

@pytest.mark.parametrize("example", find_examples(*DOCS_FILES), ids=str)
def test_docs(
    example: CodeExample,
    eval_example: EvalExample,
    datadir: Path,
):
    """Test the package's documentation."""

    globals = dict(datadir=datadir, foo=2)

    eval_example.set_config(line_length=88)
    if eval_example.update_examples:
        eval_example.format(example)
        eval_example.run_print_update(example, module_globals=globals)
    else:
        eval_example.lint(example)
        eval_example.run_print_check(example, module_globals=globals)

where my example Markdown file is picked up fine in the documentation directory, but the examples

assert datadir

and

assert foo == 2

both fail.

I can't find documentation on the feature, but would love to know how it's supposed to work!

Reproduce the failure from the issue's parametrized test using the docs/**/*.md examples and the module_globals passed to run_print_update and run_print_check. Trace those entry points to determine why datadir and foo are unavailable, then verify that both assertions pass in update and check modes.
