Pytest Type Safety

Quick Start

Add type annotations to every test function and fixture:

from __future__ import annotations

from typing import Any, AsyncGenerator
from unittest.mock import AsyncMock
import pytest

# ✅ Type annotations on fixture
@pytest.fixture
def create_test_order() -> Any:
    def _create(order_id: str = "123") -> Order:
        return Order(...)
    return _create
