这篇教程Python Pytest装饰器@pytest.mark.parametrize详解写得很实用，希望能帮到您。
Pytest中装饰器@pytest.mark.parametrize('参数名',list)可以实现测试用例参数化，类似DDT
如：@pytest.mark.parametrize('请求方式,接口地址,传参,预期结果',[('get','www.baidu.com','{"page":1}','{"code":0,"msg":"成功"})',('post','www.baidu.com','{"page":2}','{"code":0,"msg":"成功"}')]) 1、第一个参数是字符串，多个参数中间用逗号隔开 2、第二个参数是list,多组数据用元祖类型;传三个或更多参数也是这样传。list的每个元素都是一个元组，元组里的每个元素和按参数顺序一一对应
3、传一个参数 @pytest.mark.parametrize('参数名'，list) 进行参数化
4、传两个参数@pytest.mark.parametrize('参数名1，参数名2'，[(参数1_data[0], 参数2_data[0]),(参数1_data[1], 参数2_data[1])]) 进行参数化 import pytest#单参数单值@pytest.mark.parametrize("user",["18221124104"])def test(user): print(user) assert user=="18221124104" "C:/Program Files/Python35/python.exe" C:/Users/wangli/PycharmProjects/Test/test/test03.py============================= test session starts =============================platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0rootdir: C:/Users/wangli/PycharmProjects/Test/testcollected 1 item test03.py 18221124104. ============================== 1 passed in 0.15s ============================== Process finished with exit code 0 #单参数多值@pytest.mark.parametrize("user",["18221124104","18200000000","18200000001"])def test(user): print(user) assert user=="18221124104" "C:/Program Files/Python35/python.exe" C:/Users/wangli/PycharmProjects/Test/test/test03.py============================= test session starts =============================platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0rootdir: C:/Users/wangli/PycharmProjects/Test/testcollected 3 items test03.py 18221124104.18200000000F18200000001F ================================== FAILURES ===================================______________________________ test[18200000000] ______________________________ user = '18200000000' @pytest.mark.parametrize("user",["18221124104","18200000000","18200000001"]) def test(user): print(user)> assert user=="18221124104"E AssertionError test03.py:74: AssertionError______________________________ test[18200000001] ______________________________ user = '18200000001' @pytest.mark.parametrize("user",["18221124104","18200000000","18200000001"]) def test(user): print(user)> assert user=="18221124104"E AssertionError test03.py:74: AssertionError========================= 2 failed, 1 passed in 0.21s ========================= Process finished with exit code 0#多参数多值@pytest.mark.parametrize("user,pwd",[("18221124104",111111),("18200000000",111111)])def test(user,pwd): print(user,pwd) "C:/Program Files/Python35/python.exe" C:/Users/wangli/PycharmProjects/Test/test/test03.py============================= test session starts =============================platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0rootdir: C:/Users/wangli/PycharmProjects/Test/testcollected 2 items test03.py 18221124104 111111.18200000000 111111. ============================== 2 passed in 0.03s ============================== Process finished with exit code 0 # 使用内置的mark.xfail标记为失败的用例就不运行了，直接跳过显示xfailed@pytest.mark.parametrize("user,pwd",[("18221124104",111111),pytest.param("18200000000",111111,marks=pytest.mark.xfail)])def test(user,pwd): print(user,pwd) assert user == "18221124104" assert pwd== 111111 "C:/Program Files/Python35/python.exe" C:/Users/wangli/PycharmProjects/Test/test/test03.py============================= test session starts =============================platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0rootdir: C:/Users/wangli/PycharmProjects/Test/testcollected 2 items test03.py 18221124104 111111.18200000000 111111x ======================== 1 passed, 1 xfailed in 0.14s ========================= Process finished with exit code 0 #若要获得多个参数化参数的所有组合，可以堆叠参数化装饰器@pytest.mark.parametrize("x", [0, 1])@pytest.mark.parametrize("y", [2, 3])def test_foo(x, y): print("测试数据组合：x->%s, y->%s" % (x, y)) if __name__=="__main__": pytest.main(["-s","test03.py"]) "C:/Program Files/Python35/python.exe" C:/Users/wangli/PycharmProjects/Test/test/test03.py============================= test session starts =============================platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0rootdir: C:/Users/wangli/PycharmProjects/Test/testcollected 4 items test03.py 测试数据组合：x->0, y->2.测试数据组合：x->1, y->2.测试数据组合：x->0, y->3.测试数据组合：x->1, y->3. ============================== 4 passed in 0.03s ============================== Process finished with exit code 0到此这篇关于Python Pytest装饰器@pytest.mark.parametrize详解的文章就介绍到这了,更多相关pytest.mark.parametrize内容请搜索51zixue.net以前的文章或继续浏览下面的相关文章希望大家以后多多支持51zixue.net！
