完整代码示例:
def decorator(class_):
class Wrapper:
def __init__(self, *args, **kwargs):
self.instance = class_(*args, **kwargs)
@classmethod
def __getattr__(cls, attr):
return getattr(class_, attr)
return Wrapper
@decorator
class ClassTest:
static_var = "some value"
class TestSomething:
def test_decorator(self):
print(ClassTest.static_var)
assert True
尝试执行测试时,出现错误:
test/test_Framework.py F
test/test_Framework.py:37 (TestSomething.test_decorator)
self = <test_Framework.TestSomething object at 0x10ce3ceb8>
def test_decorator(self):
> print(ClassTest.static_var)
E AttributeError: type object 'Wrapper' has no attribute 'static_var'
是否可以从装饰类访问静态字段?
