• pytest文档15-使用自定义标记mark


    前言

    pytest可以支持自定义标记,自定义标记可以把一个web项目划分多个模块,然后指定模块名称执行。一个大项目自动化用例时,可以划分多个模块,
    也可以使用标记功能,标明哪些是模块1用例,哪些是模块2的,运行代码时候指定mark名称运行就可以

    mark标记

    1.以下用例,标记test_send_http()为webtest

    # content of test_server.py
    
    import pytest
    
    @pytest.mark.webtest
    def test_send_http():
        pass # perform some webtest test for your app
    
    def test_something_quick():
        pass
    
    def test_another():
        pass
    
    class TestClass:
        def test_method(self):
            pass
    
    if __name__ == "__main__":
        pytest.main(["-s", "test_server.py", "-m=webtest"])
    
    

    只运行用webtest标记的测试,cmd运行的时候,加个-m 参数,指定参数值webtest

    $ pytest -v -m webtest

    ============================= test session starts =============================
    platform win32 -- Python 3.6.0, pytest-3.6.3, py-1.5.4, pluggy-0.6.0
    rootdir: E:YOYOse, inifile:
    plugins: metadata-1.7.0, html-1.19.0
    collected 4 items / 3 deselected
    
    test_server.py .
    
    =================== 1 passed, 3 deselected in 0.10 seconds ====================
    

    如果不想执行标记webtest的用例,那就用"not webtest"

    $ pytest -v -m "not webtest"

    import pytest
    
    @pytest.mark.webtest
    def test_send_http():
        pass # perform some webtest test for your app
    def test_something_quick():
        pass
    def test_another():
        pass
    class TestClass:
        def test_method(self):
            pass
    
    if __name__ == "__main__":
        pytest.main(["-s", "test_server.py", "-m='not webtest'"])
    

    运行结果

    ============================= test session starts =============================
    platform win32 -- Python 3.6.0, pytest-3.6.3, py-1.5.4, pluggy-0.6.0
    rootdir: E:YOYOse, inifile:
    plugins: metadata-1.7.0, html-1.19.0
    collected 4 items
    
    test_server.py ....
    
    ========================== 4 passed in 0.06 seconds ===========================
    

    -v 指定的函数节点id

    如果想指定运行某个.py模块下,类里面的一个用例,如:TestClass里面test_method用例
    每个test_开头(或_test结尾)的用例,函数(或方法)的名称就是用例的节点id,指定节点id运行用-v 参数

    $ pytest -v test_server.py::TestClass::test_method

    pycharm运行代码

    if __name__ == "__main__":
        pytest.main(["-v", "test_server.py::TestClass::test_method"])
    

    运行结果

    ============================= test session starts =============================
    platform win32 -- Python 3.6.0, pytest-3.6.3, py-1.5.4, pluggy-0.6.0 -- E:python36python.exe
    cachedir: .pytest_cache
    metadata: {'Python': '3.6.0', 'Platform': 'Windows-10-10.0.17134-SP0', 'Packages': {'pytest': '3.6.3', 'py': '1.5.4', 'pluggy': '0.6.0'}, 'Plugins': {'metadata': '1.7.0', 'html': '1.19.0'}, 'JAVA_HOME': 'D:\java\jdk17'}
    rootdir: E:YOYOse, inifile:
    plugins: metadata-1.7.0, html-1.19.0
    collecting ... collected 1 item
    
    test_server.py::TestClass::test_method PASSED                            [100%]
    
    ========================== 1 passed in 0.06 seconds ===========================
    

    当然也能选择运行整个class

    $ pytest -v test_server.py::TestClass

    也能选择多个节点运行,多个节点中间空格隔开

    $ pytest -v test_server.py::TestClass test_server.py::test_send_http

    pycharm运行参考

    if __name__ == "__main__":
        pytest.main(["-v", "test_server.py::TestClass", "test_server.py::test_send_http"])
    

    -k 匹配用例名称

    可以使用-k命令行选项指定在匹配用例名称的表达式

    $ pytest -v -k http

    $ pytest -v -k http # running with the above defined example module
    =========================== test session starts ============================
    platform linux -- Python 3.x.y, pytest-3.x.y, py-1.x.y, pluggy-0.x.y -- $PYTHON_
    ˓→PREFIX/bin/python3.5
    cachedir: .pytest_cache
    rootdir: $REGENDOC_TMPDIR, inifile:
    collecting ... collected 4 items / 3 deselected
    test_server.py::test_send_http PASSED [100%]
    ================== 1 passed, 3 deselected in 0.12 seconds ==================
    

    您也可以运行所有的测试,根据用例名称排除掉某些用例:

    $ pytest -k "not send_http" -v

    =========================== test session starts ============================
    platform linux -- Python 3.x.y, pytest-3.x.y, py-1.x.y, pluggy-0.x.y -- $PYTHON_
    ˓→PREFIX/bin/python3.5
    cachedir: .pytest_cache
    rootdir: $REGENDOC_TMPDIR, inifile:
    collecting ... collected 4 items / 1 deselected
    test_server.py::test_something_quick PASSED [ 33%]
    test_server.py::test_another PASSED [ 66%]
    test_server.py::TestClass::test_method PASSED [100%]
    ================== 3 passed, 1 deselected in 0.12 seconds ==================
    

    也可以同时选择匹配 “http” 和“quick”

    $ pytest -k "http or quick" -v

    =========================== test session starts ============================
    platform linux -- Python 3.x.y, pytest-3.x.y, py-1.x.y, pluggy-0.x.y -- $PYTHON_
    ˓→PREFIX/bin/python3.5
    cachedir: .pytest_cache
    rootdir: $REGENDOC_TMPDIR, inifile:
    collecting ... collected 4 items / 2 deselected
    test_server.py::test_send_http PASSED [ 50%]
    test_server.py::test_something_quick PASSED [100%]
    ================== 2 passed, 2 deselected in 0.12 seconds ==================
