Hi, why do I get the error message "AttributeError : 'QCAlgorithm' object has no attribute 'test'" when running the following code? 

class MyQCA(QCAlgorithm):

def Initialize(self):
self.SetStartDate(2020, 9, 9)
self.test = "test"

self.UniverseSettings.Resolution = Resolution.Daily
self.symbol = Symbol.Create("TSLA", SecurityType.Equity, Market.USA)
self.SetUniverseSelection(ManualUniverseSelectionModel([self.symbol]))
self.AddAlpha(MyAlphaModel())

class MyAlphaModel:

def Update(self, algo, data):
algo.Debug(algo.test)
return []

def OnSecuritiesChanged(self, algo, changes):
pass
