determining one or more characteristics of the network communication, the characteristics including a size of a payload of the network communication;
capturing a state of the hybrid application;
transforming the intercepted network communication into a modulated network communication that simulates an effect of a network condition on the hybrid application, wherein transforming the intercepted network communication includes overriding a network communication application programming interface (API) by applying a simulator library based, at least in part, on the characteristics of the network communication and the state of the hybrid application; and
