一、fixture 之 params参数
1、字典不能单独作为fixture的传参，需要被嵌套在元组、列表中 。 如果字典作为传参，只打印字典的key 。
示例代码如下：
import pytest # fixture 参数化 # 字典不能单独作为fixture的传参，需要被嵌套在元组、列表中。 @pytest.fixture(params=data) def user_register(request): user_info = request.param print(f‘\n==========={user_info}‘) result = ‘success‘ return user_info, result def test_ee(user_register): print(f‘\n***********{user_register}‘)
执行结果如下，只打印了字典的 key 值

2、把字典嵌套在列表中传参 。
示例代码如下：
import pytest # fixture 参数化 # 原来，字典不能单独作为fixture的传参，需要被嵌套在元组、列表中。 # data = [‘sky‘, ‘123‘] # data = {‘name‘: ‘Tony‘, ‘pwd‘: ‘456‘} # data = (‘sky‘, ‘123‘) # 把字典嵌套在列表中传参 data = [ {‘name‘: ‘Tony‘, ‘pwd‘: ‘456‘}, {‘name‘: ‘jack‘, ‘pwd‘: ‘789‘} ] # data = ( # {‘name‘: ‘Tony‘, ‘pwd‘: ‘456‘}, # {‘name‘: ‘jack‘, ‘pwd‘: ‘789‘} # ) @pytest.fixture(params=data) def user_register(request): user_info = request.param print(f‘\n==========={user_info}‘) result = ‘success‘ return user_info, result def test_ee(user_register): print(f‘\n***********{user_register}‘)
执行结果如下：
