Solve the following python programming problem given the following code:
@ test.raises (AssertionError) 
def test_run_forever(self) : 
    class Controller (CementBaseController) : 
        class Meta () : 
            label = 'base' 
@ expose () 
        def runit(self) : 
            raise Exception ('Fake some error') 
app = self.make_app (base_controller = Controller, argv = ['runit']) 
    def handler(signum, frame) : 
        raise AssertionError ('It ran forever!') 
signal.signal (signal.SIGALRM, app) 
    signal.alarm (5) 
    try : 
        with app as app : 
            app.run_forever () 
except AssertionError as e : 
        self.eq (e.args [0], 'It ran forever!') 
        raise 
finally : 
        signal.alarm (0) 

    
    

    Fix the buggy line: signal.signal (signal.SIGALRM, app)
