Python unitest不起作用

Question

我開始學習TDD。我剛剛從python開始進行單元測試。當我嘗試執行：

vagrant@vagrant:~/pruebaTestPython$ python test_python_daily_software.py 

---------------------------------------------------------------------- 
Ran 0 tests in 0.000s 

OK 

我在其他links讀過，我需要在一開始與test_重命名自己的功能。然而，這正是我所做的，但它仍然不起作用。

test_python_daily_software.py文件：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

import unittest 
import python_daily 

class TestPythonSoftware(unittest.TestCase): 

    def test_should_return_python_when_number_is_3(self): 
     self.assertEqual('Python', python_daily.get_string(3)) 

    def test_should_return_daily_when_number_is_5(self): 
     self.assertEqual('Daily', python_daily.get_string(5)) 

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

和python_daily.py文件：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

def get_string(number): 
    return 'Hello' 

有什麼不好？

Answer 1

如果您python_daily.py Python模塊是：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 


def get_string(number): 
    return 'Hello' 

和你test_python_daily_software.py測試模塊是：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

import unittest 

import python_daily 


class TestPythonSoftware(unittest.TestCase): 
    def test_should_return_python_when_number_is_3(self): 
     self.assertEqual('Python', python_daily.get_string(3)) 

    def test_should_return_daily_when_number_is_5(self): 
     self.assertEqual('Daily', python_daily.get_string(5)) 


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

你應該有：

$ python test_python_daily_software.py 
FF
