Python+Unittest参数化之parameterized数据驱动

一、parameterized介绍
Unittest第三方库parameterized类似Python数据驱动模块DDT、[email protected]【Pytest篇】装饰器@pytest.mark.parametrize多样参数化（二）Pytest装饰器@pytest.mark.parametrize数据驱动（三）可以实现参数化用户数据驱动，避免写多个方法（冗余）
二、安装
pip install parameterized
三、导入
from parameterized import parameterized,param
四、实例
1、实现2个参数相加等于第3个参数，我们可以看到，参数是以列表形式传入的，根据参数个数，迭代不同次数
from parameterized import parameterized,param import unittest import requests class Test(unittest.TestCase): @parameterized.expand([param(1,2,3),param('he','llo','hello')]) def test(self,test1,test2,test3): self.assertEqual((test1+test2),test3) if __name__ == '__main__': unittest.main() Testing started at 12:36 ... "C:Program FilesPython35python.exe" "C:Program FilesJetBrainsPyCharm Community Edition 2018.2.4helperspycharm_jb_unittest_runner.py" --path C:/Users/wangli/PycharmProjects/Test/test/test01.py Launching unittests with arguments python -m unittest C:/Users/wangli/PycharmProjects/Test/test/test01.py in C:UserswangliPycharmProjectsTesttest Ran 2 tests in 0.001s OK Process finished with exit code 0
2、我们可以通过上面方法实现我们测试用例的迭代，将测试用例的请求参数组装成列表形式，传给@parameterized.expand([参数1，参数2，参数3])，实现测试用例的多次迭代，避免写多个测试方法
from parameterized import parameterized,param import unittest import requests class Test(unittest.TestCase): @parameterized.expand([param('url','headers','data1'),param('url','headers','data2')]) def test(self,url,headers,data): print(url,headers,data) r=requests.post(url=url,headers=headers,json=data) if __name__ == '__main__': unittest.main() Testing started at 12:46 ... "C:Program FilesPython35python.exe" "C:Program FilesJetBrainsPyCharm Community Edition 2018.2.4helperspydevpydevd.py" --multiproc --qt-support=auto --client 127.0.0.1 --port 1145 --file "C:Program FilesJetBrainsPyCharm Community Edition 2018.2.4helperspycharm_jb_unittest_runner.py" --path C:/Users/wangli/PycharmProjects/Test/test/test01.py pydev debugger: process 24756 is connecting Connected to pydev debugger (build 182.4505.26) Launching unittests with arguments python -m unittest C:/Users/wangli/PycharmProjects/Test/test/test01.py in C:UserswangliPycharmProjectsTesttest Ran 2 tests in 0.004s OK url headers data1 url headers data2 Process finished with exit code 0
