pytest -mark

pytest.mark是 pytest 核心功能，用于给测试函数 / 类打标签，实现分类、筛选、条件执行、参数化等。常用@pytest.mark.xxx装饰器 + 命令行-m筛选。一、常用内置标记1. skip /skipif：跳过测试python运行import pytest import sys @pytest.mark.skip(reason="功能未实现，暂不执行") def test_feature_not_done(): assert False # 条件跳过（Python 3.10+ 才执行） @pytest.mark.skipif(sys.version_info (3,10), reason="需要 Python 3.10+") def test_py310_feature(): pass2. xfail：预期失败python运行@pytest.mark.xfail(reason="已知Bug，待修复") def test_known_bug(): assert 1 == 2 # 失败会显示 XFAIL（预期失败）3. parametrize：参数化（数据驱动）python运行# 单参数 @pytest.mark.
