为什么doctest没有检测到我的测试？

Question

class Test: 
    def __init__(self): 
     pass 

    ''' 
    This function parses a name according to following rules - 

    >>> Test().name('Kshitiz Sharma') 
    Sharma, Kshitiz 

    ''' 
    def name(self, name): 
     name = name.split() 
     return name[1] + ", " + name[0] 

if __name__ == "__main__": 
    import doctest 
    doctest.testmod() 

输出是 -

4 items had no tests: 
    __main__ 
    __main__.Test 
    __main__.Test.__init__ 
    __main__.Test.name 
0 tests in 4 items. 
0 passed and 0 failed. 
Test passed. 

哪里是我的测试？

Answer 1

将docstring放入方法中。

def name(self, name): 
    ''' 
    This function parses a name according to following rules - 

    >>> name('Kshitiz Sharma') 
    <BLANKLINE> 

    ''' 
    pass 

而且上运行的方法测试无误，您需要实际实例化类测试本身期间有机会获得方法：

>>> t = Test(); t.name('Kshitiz Sharma') 
    <BLANKLINE>
