pytest 给用例打标签

1.给用例添加自定义标签命令：@pytest.mark.tagname     #tagname是自定义的标签名

import pytest

class TestClass():
    @pytest.mark.smoke
    def test_one(self):
        print("test_one方法执行")
        assert  1==1
    @pytest.mark.回归测试
    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

2.根据标签运行测试用例：pytest -m tagname

C:\Users\cale\checkapi\test_cc>pytest test_m1.py -m smoke -s

test_m1.py test_one方法执行
.

3.因为自定义的标签没有注册，所以在运行时会出现警告的信息,pytest注册标签有两种方法

（1）：注册pytest.ini文件（在当前目录创建pytest.ini文件）

[pytest]
markers=
     smoke:冒烟测试   #冒号后面是标签的描述，可不填
     two
     回归测试         #如果标签是中文，编码需对应进行修改

再看下运行结果：警示信息没有了

C:\Users\cale\checkapi\test_cc>pytest test_m1.py  -s ========================================================================= test session starts ========================================================================= platform win32 -- Python 3.7.3, pytest-5.2.1, py-1.8.0, pluggy-0.13.0 rootdir: C:\Users\cale\checkapi\test_cc, inifile: pytest.ini plugins: allure-pytest-2.8.13, html-2.0.0, metadata-1.8.0, rerunfailures-7.0 collected 2 items test_m1.py test_one方法执行 .test_two方法执行 . ========================================================================== 2 passed in 0.13s ==========================================================================

（2）：写钩子到conftest.py(在命令行当前目录下创建conftest.py)

 

def pytest_configure(config): config.addinivalue_line("markers",'smoke') config.addinivalue_line("markers", '回归测试')

运行结果如下 

C:\Users\cale\checkapi\test_cc>pytest test_m1.py  -s
=========================================================================================================== test session starts ============================================================================================================
platform win32 -- Python 3.7.3, pytest-5.2.1, py-1.8.0, pluggy-0.13.0

test_m1.py test_one方法执行
.test_two方法执行
.

============================================================================================================ 2 passed in 0.09s =============================================================================================================

 4.在一个测试用例上打多个标签

import pytest


@pytest.mark.smoke @pytest.mark.回归测试 def test_one(self):
        print("test_one方法执行")
        assert  1==1

5.给测试类打标签

import pytest

#方式一
@pytest.mark.smoke
class TestClass():
      def test_one(self):
            print("test_one方法执行")
            assert  1==1
#方式二
class TestClass():
　　　 pytestmark=[pytest.mark.smoke,pytest.mark.回归测试]  #多个标签存在列表里面

 def test_one(self): print("test_one方法执行") assert 1==1
