pytest_使用自定義標記mark

前言

pytest可以支持自定義標記，自定義標記可以把一個web項目划分多個模塊，然后指定模塊名稱執行。app自動化的時候，如果想android和ios公用一套代碼時，
也可以使用標記功能，標明哪些是ios用例，哪些是android的，運行代碼時候指定mark名稱運行就可以

mark標記

1.以下用例，標記test_send_http()為webtest

import pytest

@pytest.mark.webtest
def test_send_http():
    print("890")# perform some webtest test for your app

def test_something_quick():
    print("123")

def test_another():
    print("456")

class TestClass:
    def test_merhed(self):
        print("678")

if __name__ == '__main__':
    pytest.main(['-s', 'mark_01.py', "-m=webtest"])

只運行用webtest標記的測試，cmd運行的時候，加個-m 參數，指定參數值webtest

$ pytest -v -m webtest

mark_01.py 890
.


=================== 1 passed, 3 deselected in 0.10 seconds ====================

如果不想執行標記webtest的用例，那就用"not webtest"

$ pytest -v -m "not webtest"

import pytest

@pytest.mark.webtest
def test_send_http():
    print("890")# perform some webtest test for your app

def test_something_quick():
    print("123")

def test_another():
    print("456")

class TestClass:
    def test_merhed(self):
        print("678")

if __name__ == '__main__':
    pytest.main(['-s', 'mark_02.py', "-m='not webtest'"])

運行結果

mark_02.py 890
.123
.456
.678
.

========================== 4 passed in 0.02 seconds ===========================

-v 指定的函數節點id

如果想指定運行某個.py模塊下，類里面的一個用例，如：TestClass里面test_method用例
每個test_開頭(或_test結尾)的用例，函數(或方法)的名稱就是用例的節點id，指定節點id運行用-v 參數

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

pycharm運行代碼

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

運行結果

============================= test session starts =============================

test_server.py::TestClass::test_method PASSED                            [100%]

========================== 1 passed in 0.06 seconds ===========================

當然也能選擇運行整個class

$ pytest -v test_server.py::TestClass

也能選擇多個節點運行，多個節點中間空格隔開

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

pycharm運行參考

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

-k 匹配用例名稱

可以使用-k命令行選項指定在匹配用例名稱的表達式

$ 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

collecting ... collected 4 items / 3 deselected
test_server.py::test_send_http PASSED [100%]
================== 1 passed, 3 deselected in 0.12 seconds ==================

您也可以運行所有的測試，根據用例名稱排除掉某些用例：

$ pytest -k "not send_http" -v

=========================== test session starts ============================

test_server.py::test_another PASSED [ 66%]
test_server.py::TestClass::test_method PASSED [100%]
================== 3 passed, 1 deselected in 0.12 seconds ==================

也可以同時選擇匹配 “http” 和“quick”

$ pytest -k "http or quick" -v
