实际上pytest-order不允许添加两个order标记。但是我为您想到了一些解决方案。
你可以使用pytest_generate_tests pytest钩子来解析这个语法，只需要把它添加到你的conftest.py文件中。
以下示例将读取所有pytest.mark.order标记，并对其进行参数化测试（如果提供了多个顺序标记）。它添加了名为order的参数，该参数存储pytest.mark.order中指定的参数。

                    mark for mark in marks if mark.name != "order"

• • 测试订单. py**

import pytest

@pytest.mark.order(6)
@pytest.mark.order(4)
def test_4_and_6():
    pass

@pytest.mark.order(5)
@pytest.mark.order(3)
@pytest.mark.order(1)
def test_1_3_and_5():
    pass

@pytest.mark.order(2)
def test_2():
    pass

• • pytest test_order.py -v输出**

我已经更新了hook，使它与pytest-order的其他特性兼容。另外，我还创建了PR in pytest-order GitHub repo。
