pytest fixture-使用参数化fixture标记

​​Pytest.param()​​可用于在参数化​​fixture​​的值集中应用标记，其方式与​​@pytest.mark. parameterize​​的使用方式相同。

例如：

# content of test_fixture_marks.py
import pytest


@pytest.fixture(params=[0, 1, pytest.param(2, marks=pytest.mark.skip)])
def data_set(request):
    return request.param


def test_data(data_set):
    pass

运行这个测试将跳过值为2的​​data_set​​调用:

$ pytest test_fixture_marks.py -v
