在同一測試中重用pytest夾具

Question

以下是使用user夾具設置測試的測試代碼示例。

@pytest.fixture
def user():
    # Setup db connection
    yield User('test@example.com')
    # Close db connection

def test_change_email(user):
    new_email = 'new@example.com'
    change_email(user, new_email)
    assert user.email == new_email

如果我想例如添加一些功能來批量更改用戶電子郵件，並且需要在測試之前設置10個用戶，是否可以使用同一夾具在同一測試中生成多個用戶對象？

pytest文檔的“ 工廠作為固定裝置 ”部分解決了我的問題。

特別是此示例（從鏈接復制/粘貼）：

@pytest.fixture
def make_customer_record():

    created_records = []

    def _make_customer_record(name):
        record = models.Customer(name=name, orders=[])
        created_records.append(record)
        return record

    yield _make_customer_record

    for record in created_records:
        record.destroy()


def test_customer_records(make_customer_record):
    customer_1 = make_customer_record("Lisa")
    customer_2 = make_customer_record("Mike")
    customer_3 = make_customer_record("Meredith")
