Solve the following python programming problem given the following code:
@ testing.teardown_events (orm_events.MapperEvents) 
def test_declare_first_base(self) : 
    canary = mock.Mock () 
    class MyMixin (object) : 
        @ classmethod 
        def __declare_first__(cls) : 
            canary.declare_first__ (cls) 
@ classmethod 
        def __declare_last__(cls) : 
            canary.declare_last__ (cls) 
class Base (MyMixin) : 
        pass 
Base = declarative_base (cls = Base) 
    class MyModel (Base) : 
        __tablename__ = 'test' 
        id = Column (Integer, primary_key = True) 
configure_mappers () 
    eq_ (self.mock_calls, [mock.call.declare_first__ (MyModel), mock.call.declare_last__ (MyModel)]) 

    
    

    Fix the buggy line: eq_ (self.mock_calls, [mock.call.declare_first__ (MyModel), mock.call.declare_last__ (MyModel)])

#Here is Python code to fix the buggy line: eq_ (self.

eq_ (canary.mock_calls, [mock.call.declare_first__ (MyModel), mock.call.declare_last__ (MyModel)])
