Example
import pytest
@pytest.fixture
def sample_user():
return {"id": 1, "name": "Alice", "email": "alice@example.com"}
@pytest.fixture
def db_connection():
conn = create_test_db()
yield conn # setup done
conn.close() # teardown
def test_user_name(sample_user):
assert sample_user["name"] == "Alice"
def test_save_user(db_connection, sample_user):
save(db_connection, sample_user)
assert find(db_connection, 1)["name"] == "Alice" Pro Tip
Use yield in fixtures for teardown — code after yield runs after the test completes.
