Python unittest 模块

最近在找一些Python 自带的模块的时候，发现一个小东东还很好玩的

我们写好一些方法后要去对这个方法做单元测试

Python 刚好有提供这样的模块，也很方便

下面的方法是从 Unittest.py 里找出来的

代码

import unittest

class IntegerArithmenticTestCase(unittest.TestCase):
    def testAdd(self):  ## test method names begin 'test*'
        self.assertEquals((2 + 2), 3)
        self.assertEquals(0 + 1, 1)
    def testMultiply(self):
        self.assertEquals((0 * 10), 0)
        self.assertEquals((5 * 8), 40)

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

How to execute them ?

1. Create a file name "studyUnitTest.py"

2. Add above code into this file

3. Execute the script ,then you will find the result ,as follows

wenlezhou >>> python studyUnitTest.py
