    app.config ['TESTING'] = True 
    @ app.route ('/api/people/<firstname>') 
    def sayHello(firstname) : 
        return firstname 
flask_profiler.init_app (sayHello) 
    @ app.route ('/api/without/profiler') 
    def withoutProfiler() : 
        return 'without profiler' 
@ app.route ('/api/with/profiler/<message>') 
    @ flask_profiler.profile () 
    def customProfilerEP(message) : 
        return 'with profiler'
