Ctypes包装器和单元测试

Question

我希望包装一个在python中使用的C库。我还希望使用测试驱动开发来实现我的类。下面是我目前为止编写的两个类及其接口。有一大堆像这样的课程我需要包装。在

class FunctionWrapperForOurLibrary:
    def __init__():
        pass

    def __call__():
        pass

class OurOpener(FunctionWrapperForOurLibrary):
    def __init__(self, our_library):
        self.our_library = our_library
        our_library.OurOpen.argtypes = [c_char_p, c_char_p]
        our_library.OurOpen.restype = OUR_ERROR

    def __call__(self, admin_path, company_path):
        status = self.our_library.OurOpen(admin_path, company_path)
        if status.lRc:
            raise Exception("Unable to connect to database due to this error: "+str(status.lRc))

class OurDataCreator(FunctionWrapperForOurLibrary):
    def __init__(self, our):
        self.our_library = our_library
        our_library.OurCreateData.argtypes = [c_int]
        our_library.OurCreateData.restype = POINTER(OUR_DATA)

    def __call__(self, our_structure_type):
        data = self.our_library.OurCreateData(our_structure_type)
        return data

第一个问题，我是否通过包含接口类来帮助可读性？我知道不需要。我的对象名和类名呢。有什么建议可以让这些更清楚？在

第二，如何编写一个包含这些函子的类？一个可以单元测试的类？在

我能想到的最好的办法是：

^{pr2}$

但是我将有大量的函子传递给类构造函数。在

做这个更好吗？在

更新：

class Our:
    def __init__(self, our_library):
        self.our_library = our_library
        our_library.OurOpen.argtypes = [c_char_p, c_char_p]
        our_library.OurOpen.restype = OUR_ERROR
        our_library.OurCreateData.argtypes = [c_int]
        our_library.OurCreateData.restype = POINTER(OUR_DATA)

    def open(self, admin_path, company_path):
        status = self.our_library.OurOpen(admin_path, company_path)
        if status.lRc:
            raise Exception("Unable to connect to database due to this error: "+str(status.lRc))

    def create_data(self, our_structure_type):
        return self.our_library.OurCreateData(our_structure_type)
