python单元测试

复杂运行

导入unittest模块中的TestCase方法

写好一个方法

写好一个类来运行测试用例 self.assertEqual（预期结果，实际结果，实际和预期对不上时默认提示可省）

实例化类

运行

eg：

 1 from unittest import TestCase
 2 
 3 def calc(a,b):
 4     c = a//b
 5     return c
 6 
 7 class MyTest(TestCase):
 8     def calc1(self):
 9         #正常的测试用例
10         res = calc(4,2)
11         self.assertEqual(2,res,'预期结果和实际结果不符合 预期结果是 2 实际结果是%s'%res)#断言
12 
13     def calc2(self):
14             # 不正常的测试用例
15         res = calc(5, 1)
16         self.assertEqual(1, res)
17 
18 m = MyTest()
19 m.calc1()
20 m.calc2()

用unittest.main()全部运行，用例必须是以test开头

 1 import unittest
 2 from unittest import TestCase
 3 
 4 def calc(a,b):
 5     c = a//b
 6     return c
 7 
 8 class MyTest(TestCase):
 9     def test_calc1(self):
10         #正常的测试用例
11         res = calc(4,2)
12         self.assertEqual(2,res,'预期结果和实际结果不符合 预期结果是 2 实际结果是%s'%res)#断言
13 
14     def test_calc2(self):
15             # 不正常的测试用例
16         res = calc(5, 1)
17         self.assertEqual(1, res)
18 unittest.main()

运行结果：
