    subTestview.view.frame = CGRectMake(0, 0, subTestview.view.frame.size.width,
                                        subTestview.view.frame.size.height);
    subTestview.view.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2);

I think, you should make another parent view. Put your testView on it. Put your subTestview on it also independently(not as a subview of testView, but as a subview of parent view). Try to set alpha of your testView after that.
