unittest数据参数化

Posted 2021-01-11 mollylin

unittest本身不支持参数化，但是可以借助其他方法

1、unittest中使用第3方插件parameterized进行参数化

首先在DOS中键入以下命令安装parameterized
python -m pip install parameterized

导包：
from parameterized import parameterized

例：

 1 import unittest
 2 from pylibrary.PyLib import *
 3 
 4 class   Interface_Report2(unittest.TestCase):
 5 
 6 #开始使用parameterized
 7     @parameterized.expand([   #引用装饰器，准备参数，传入下方的函数
 8         ("2018-09-26", ‘2018-09-26‘, "测试", "2001",49,‘TotalCallNum‘),
 9         ("2018-09-26", ‘2018-09-26‘, "测试", "2001",60,‘TotalCallAnsweredNum‘),
10         ("2018-09-26", ‘2018-09-26‘, "测试", "2001",60,‘RingNum‘),
11         ("2018-09-13", ‘2018-09-13‘, "测试", "2001",4,‘TotalCallNum_Transfer‘),
12     ])
13 
14 
15     def test_Agreport1(self,start_time,end_time,template_name,ag_num,testData,reportData):   #当执行到此会自动接收上面传入的参数
16         self.num = testData
17         self.report_num1 = PyLib().getAgReport(start_time,end_time,template_name,ag_num)
18         self.report_num=self.report_num1[0][reportData]
19         self.assertEqual(self.num,self.report_num)
20 
21 if  __name__ == ‘__main__‘:
22 
23     unittest.main(verbosity=2)
24 
25 #verbosity表示测试结果的信息复杂度，分别使用0,1,2，其具体的含义如下：
26 #0（静默模式）：仅仅获取总的测试用例数以及总的结果
27 #1（默认模式）：此时在每个成功的用例前面有个’.’,每个失败的用例前面有个’F’
28 #2(详细模式)：测试结果会显示每个测试用例的所有相关信息

2、unittest的ddt库

pip install ddt

首先创建一个数据文件：test_ddt_file.json

 1 {
 2     "test_Agreport1_01":{
 3         "start_time":"2018-09-26",
 4         "end_time":"2018-09-26",
 5         "template_name": "测试",
 6         "ag_num":"2001",
 7         "testData":49,
 8         "reportData":"TotalCallNum"
 9     },
10     "test_Agreport1_02":{
11         "start_time":"2018-09-26",
12         "end_time":"2018-09-26",
13         "template_name": "测试",
14         "ag_num":"2001",
15         "testData":60,
16         "reportData":"TotalCallAnsweredNum"
17     },
18     "test_Agreport1_03":{
19         "start_time":"2018-09-26",
20         "end_time":"2018-09-26",
21         "template_name": "测试",
22         "ag_num":"2001",
23         "testData":60,
24         "reportData":"RingNum"
25     },
26     "test_Agreport1_04":{
27         "start_time":"2018-09-13",
28         "end_time":"2018-09-13",
29         "template_name": "测试",
30         "ag_num":"2001",
31         "testData":4,
32         "reportData":"TotalCallNum_Transfer"
33     }
34 }

创建测试用例：

 1 import unittest
 2 from pylibrary.PyLib import *
 3 from ddt import ddt, file_data
 4 
 5 
 6 @ddt
 7 class   Interface_Report2(unittest.TestCase):
 8 
 9     @file_data("D:\Python_code\test_ddt_file.json")
10     def test_Agreport1(self,start_time,end_time,template_name,ag_num,testData,reportData):
11         self.num = testData
12         self.report_num1 = PyLib().getAgReport(start_time,end_time,template_name,ag_num)
13         self.report_num=self.report_num1[0][reportData]
14         self.assertEqual(self.num,self.report_num)
15 
16 
17 
18 if  __name__ == ‘__main__‘:
19 
20     unittest.main(verbosity=2)
