1. 使用 @pytest.mark.smoke 标记用例

import pytest
class Test_Smoke:
    def test_01(self):
        assert 1+1==2
    @pytest.mark.smoke
    def test_02(self):
        assert 1+2==1

    @pytest.mark.smoke
    def test_03(self):
        assert 1 + 2 == 3

2.配置文件pytest.ini

[pytest]
markers =
	smoke

3.  运行指定标签  运行指定标签 pytest -m "标记名"

#----------------------------冒烟用例标记--------------------------------------
    pytest.main(['-s', '-v','-m smoke','./somke_test', '--html=./report/result.html'])
