Python 中的属性错误
我正在尝试向 Python 中的对象添加单元测试属性，
class Boy:
def run(self, args):
print("Hello")
class BoyTest(unittest.TestCase)
def test(self)
self.assertEqual('2' , '2')
def self_test():
suite = unittest.TestSuite()
loader = unittest.TestLoader()
suite.addTest(loader.loadTestsFromTestCase(Boy.BoyTest))
return suite
但是，每当我调用 self_test() 时，我都会收到“AttributeError: class Boy has no attribute 'BoyTest'” >。为什么？
I'm trying to add a unittest attribute to an object in Python
class Boy:
def run(self, args):
print("Hello")
class BoyTest(unittest.TestCase)
def test(self)
self.assertEqual('2' , '2')
def self_test():
suite = unittest.TestSuite()
loader = unittest.TestLoader()
suite.addTest(loader.loadTestsFromTestCase(Boy.BoyTest))
return suite
However, I keep getting "AttributeError: class Boy has no attribute 'BoyTest'" whenever I call self_test(). Why?

作为
loadTestsFromTestCase的参数，您尝试访问Boy.BoyTest，即类对象Boy< 的BoyTest属性/code>，它根本不存在，正如错误消息告诉您的那样。为什么不直接使用BoyTest呢？As the argument of
loadTestsFromTestCase, you're trying to accessBoy.BoyTest, i.e., theBoyTestattribute of class objectBoy, which just doesn't exist, as the error msg is telling you. Why don't you just useBoyTestthere instead?正如 Alex 所说，您正在尝试使用 BoyTest 作为 Boy 的属性：

这可以解决您的问题吗？
As Alex has stated you are trying to use BoyTest as an attibute of Boy:
