Access self from decorator

python, scope, unit-testing

Solution

Since you're decorating a method, and `self` is a method argument, your decorator has access to `self` at runtime. Obviously not at parsetime, because there are no objects yet, just a class.

So you change your decorator to:

def decorator(func):
    def _decorator(self, *args, **kwargs):
        # access a from TestSample
        print 'self is %s' % self
        return func(self, *args, **kwargs)
    return _decorator

Problem

In setUp() method of unittest I've setup some self variables, which are later referenced in actual tests. I've also created a decorator to do some logging. Is there a way in which I can access those self variables from decorator? For the sake of simplicity, I'm posting this code: ``` def decorator(func): def _decorator(*args, **kwargs): # access a from TestSample func(*args, **kwargs) return _decorator class TestSample(unittest.TestCase): def setUp(self): self.a = 10 def tearDown(self): # tear down code @decorator def test_a(self): # testing code goes here ``` What would be the best way of accessing a (set in setUp()) from decorator?
