是否有可能在單元測試中的一個文件中有2個測試類

Question

import .... 

class Test1: 

    @classmethod 
    def setUpClass(self): 
    ... 

    def test_something(self): 
    ... 

    @classmethod 
    def tearDownClass(self): 
    ... 

class Test2: 

    @classmethod 
    def setUpClass(self): 
    ... 

    def test_anotherthing(self): 
    ... 

    @classmethod 
    def tearDownClass(self): 
    ... 

if __name__ == '__main__': 
    unittest2.main() 

Answer 1

是的。你爲什麼不給它一個旋風？

下面是一個例子，在我的測試類從unittest.TestCase繼承和測試故意失敗：

#!/usr/bin/env python 

import unittest 

class TestAddition(unittest.TestCase): 

    def test_addition(self): 
     self.assertEquals(3, 1 + 1) 

class TestSubtraction(unittest.TestCase): 

    def test_subtraction(self): 
     self.assertEquals(3, 1 - 1) 

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

% ./t.py 
FF 
====================================================================== 
FAIL: test_addition (__main__.TestAddition) 
---------------------------------------------------------------------- 
Traceback (most recent call last): 
    File "./t.py", line 8, in test_addition 
    self.assertEquals(3, 1 + 1) 
AssertionError: 3 != 2 

====================================================================== 
FAIL: test_subtraction (__main__.TestSubtraction) 
---------------------------------------------------------------------- 
Traceback (most recent call last): 
    File "./t.py", line 13, in test_subtraction 
    self.assertEquals(3, 1 - 1) 
AssertionError: 3 != 0 

----------------------------------------------------------------------

Answer 2

當然，這是可能的，只要確保它們從unittest.TestCase繼承。然後，unittest.main將發現並運行它們。

您還可以通過使用unittest.TestLoader().loadTestsFromTestCase或unittest.TestLoader().loadTestsFromNames方法在文件中運行一些測試。
