Pytest如何在测试之间传递参数/数据？

import pytest

@pytest.fixture
def data():
    return {'name': 'John', 'age': 30}

def test_name(data):
    assert data['name'] == 'John'

def test_age(data):
    assert data['age'] == 30

import pytest

@pytest.fixture
def data():
    return {'name': 'John', 'age': 30}

@pytest.mark.usefixtures('data')
def test_name():
    assert data['name'] == 'John'

@pytest.mark.usefixtures('data')
def test_age():
    assert data['age'] == 30
