Question

以下是使用user夹具设置测试的测试代码示例。

@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

有没有办法在相同的测试中使用相同的灯具生成多个用户对象，如果我想例如添加批量更改用户电子邮件的功能，在测试前需要设置10个用户？

pytest文档有一个“factories as fixtures” - 部分解决了我的问题。

特别是这个例子（从链接中复制/粘贴）：

@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")

在同一测试中重用pytest fixture
