对于nose中的装饰器make_decorator的理解

          nose.tools.make_decorator(func)

Wraps a test decorator so as to properly replicate metadata of the decorated function, including nose’s additional stuff (namely, setup and teardown)

from nose.tools import make_decorator, with_setup

def setup_func():
    print "setup"




def teardown_func():
    print "teardown"




@with_setup(setup_func, teardown_func)
def test1():
    pass




@make_decorator(test1)
def test2():
    pass

运行的结果如下：setupteardown.setupteardown.----------------------------------------------------------------------Ran 2 tests in 0.005sOK分析：从运行结果中可以看到，使用make_decorator(test1)来装饰test2后test2也有了setup和teardown的效果；从开头引用文档的字面意思解释：使用make_decorator()使得test2是复制了test1的metadata只是我不是特别清楚，metadata具体包含哪些内容呢？一时之间也没能找到权威的解释，如有朋友了解，请不吝赐教！
