Pytest中我們經常會用到數據參數化，我們來介紹下裝飾器@pytest.fixture()配合request傳參的使用

user = request.param

如果想把登錄操作放到前置操作里，也就是用到@pytest.fixture裝飾器，傳參就用默認的request參數
user = request.param 這一步是接收傳入的參數，本案例是傳一個參數情況

?

@pytest.mark.parametrize("input_user",user_list,indirect=True)中indirect=True

是指用user_list、pwd_list數據對“input_user”、“input_pwd”這個fixture進行參數化，雖然裝飾器寫在測試用例上，但是卻是對測試用例使用的fixture進行傳遞數據，這正是indirect的意思.

request傳多個參數、多個fixtrue

import pytest user_list=['wangxiao','zhangxiao'] pwd_list=['123456','123'] @pytest.fixture(scope="module") def input_user(request):user=request.paramprint("用戶名：%s"%user)return user @pytest.fixture(scope="module") def input_pwd(request):pwd = request.paramprint("密碼：%s"%pwd)return pwd @pytest.mark.parametrize("input_user",user_list,indirect=True) @pytest.mark.parametrize("input_pwd",pwd_list,indirect=True) def test_login(input_user,input_pwd):print(input_user,input_pwd) if __name__=='__main__':pytest.main(['-s','test01.py'])"C:\Program Files\Python35\python.exe" C:/Users/wangli/PycharmProjects/Test/test/test01.py ============================= test session starts ============================= platform win32 -- Python 3.5.2, pytest-5.1.2, py-1.8.0, pluggy-0.12.0 rootdir: C:\Users\wangli\PycharmProjects\Test\test plugins: allure-pytest-2.8.5, html-1.22.0, metadata-1.8.0 collected 4 itemstest01.py 用戶名：wangxiao 密碼：123456 wangxiao 123456 .用戶名：zhangxiao zhangxiao 123456 .密碼：123 zhangxiao 123 .用戶名：wangxiao wangxiao 123 .============================== 4 passed in 0.06s ==============================Process finished with exit code 0
