1、parameterized.parameterized

import unittest
from parameterized import parameterized,param

class TestAdd(unittest.TestCase):
    ss = [
        {'first': 1, 'second': 3, 'third': 5},
        {'first': 4, 'second': 7, 'third': 8},
        {"first": {'username': '15669910105'}}]
    
    @parameterized.expand([param(s) for s in ss])   #只能取出list的str元素
    def test_add(self,data):
        print(data)
        print(data["first"])

if __name__ == '__main__':
    #Pycharm执行时注意鼠标需要放在 unittest.main(verbosity=2)代码块的位置，否则会报错
    unittest.main(verbosity=2)  # verbosity表示测试结果的信息复杂度

2、pytest.mark.parametrize

import pytest

datas = [
    {'first': 1, 'second': 3, 'third': 5},
    {'first': 4, 'second': 7, 'third': 8},
    {"first": {'username': '15669910105'}}
]

@pytest.mark.parametrize("data",datas)
def test_(data):
    print(data)

if __name__ == '__main__':
    pytest.main(['-s', 'demo8.py'])  #以print信息显示

3、ddt、unpack

import unittest
from ddt import ddt,data,unpack

datas =  [
    {'first': 1, 'second': 3, 'third': 5},
    {'first': 4, 'second': 7, 'third': 8}
]
@ddt
class MyTesting(unittest.TestCase):
    def setUp(self):
        print('this is the setUp')

    @data(*datas)
    @unpack
    def test_dicts(self, first, second, third):
        print(first,second,third)

    def tearDown(self):
        print('this is tearDown')

if __name__ == '__main__':
    unittest.main(verbosity=2)
