Abstract

A virtual instance of a hardware device is generated from device profile model data. The virtual instance of the hardware device simulates operation of the hardware device. The simulated operation includes interacting with a software service over a network connection by generating, at the virtual instance, message data to push to a host of the software service over the network connection, receiving request data from the software service over the network connection, and generating a simulated response to the request data. The simulated operation further includes sending the simulated response from the virtual instance to the host over the network connection and modeling a physical effect measured by the hardware device during the interaction with the software service. Data sent by the virtual instance during the interaction is based on the modeled physical effect.

generating a virtual instance of a hardware device from device profile model data, wherein the virtual instance of the hardware device is to simulate operation of the hardware device, and the simulated operation comprises:
interacting with a software service over a network connection, wherein the interaction comprises:
generating, at the virtual instance, message data to push to a host of the software service over the network connection;
receiving request data from the software service over the network connection; and
generating a simulated response to the request data; and
sending the simulated response from the virtual instance to the host over the network connection; and

modeling a physical effect measured by the hardware device during the interaction with the software service, wherein data sent by the virtual instance during the interaction is based on the modeled physical effect.

2 . The method of claim 1 , wherein subsequent consumption of the software service is based on the physical effect.

3 . The method of claim 1 , wherein the hardware device comprises a mobile, battery-powered device and the physical effect comprises consumption of a battery by the hardware device.

4 . The method of claim 3 , wherein the device profile model data defines a relationship between an action performed by the hardware device corresponding to consumption of the software service and an amount of battery life expended based on the action.

5 . The method of claim 4 , wherein the action comprises sending data from the hardware device to the host.

6 . The method of claim 4 , wherein the action comprises an operating mode of the hardware device.

7 . The method of claim 3 , wherein the virtual instance is to simulate unavailability of the hardware device in the interaction upon modeling insufficient battery life.

8 . The method of claim 1 , wherein the physical effect comprises consumption of computer memory associated with the hardware device.

9 . The method of claim 1 , wherein the physical effect corresponds to events, to be detected by the hardware device, of a physical entity associated with the hardware device.

10 . The method of claim 9 , wherein the device profile model data defines a model of occurrences of the events of the physical entity.

11 . The method of claim 9 , wherein the physical entity comprises a physical product monitored by or integrated with the hardware device.

12 . The method of claim 9 , wherein the physical entity comprises a living entity.

13 . The method of claim 1 , wherein the simulated response is generated based on a request-response model based on prior monitored transactions involving a version of the software service and an instance of the hardware device.

14 . A computer program product comprising a computer readable storage medium comprising computer readable program code embodied therewith, the computer readable program code comprising:
computer readable program code configured to generate a virtual instance of a hardware device from device profile model data, wherein the virtual instance of the hardware device is to simulate operation of the hardware device, and the simulated operation comprises:
interacting with a software service over a network connection, wherein the interaction comprises:
generating, at the virtual instance, message data to push to a host of the software service over the network connection;
receiving request data from the software service over the network connection; and
generating a simulated response to the request data; and
sending the simulated response from the virtual instance to the host over the network connection; and

modeling a physical effect measured by the hardware device during the interaction with the software service, wherein data sent by the virtual instance during the interaction is based on the modeled physical effect.

15 . A method comprising:
receiving, through a graphical user interface, selection of a set of hardware devices to be modeled in association with a test of a software program, wherein the hardware devices are configured to interact with the software program over a network; and instantiating virtual instances of each hardware device in the set of hardware devices, wherein each virtual instance is to:
push a message to a host of the software program over the network to simulate a push message to be transmitted by the hardware device corresponding to the virtual instance;
receive a request from the software program over the network;
generate a simulated response to the request;
send the simulated response to the host over the network connection; and
model a physical effect measured by the hardware device during interoperation with the software program, wherein one of the message and response data are based on the modeled physical effect.

16 . The method of claim 15 , wherein each virtual instance is instantiated from a respective device profile, and each device profile defines respective models for the corresponding hardware device.

17 . The method of claim 16 , wherein the models comprise one of a request-response model and a push event model, and one of a hardware services model and a business services model.

18 . The method of claim 16 , further comprising receiving, through the graphical user interface, selection of a model attribute of the device profile to be applied to a particular one of the instantiated virtual instances.

19 . The method of claim 15 , further comprising monitoring performance of the software program in interoperation with the virtual instances.

20 . The method of claim 15 , wherein the set of hardware devices comprises a plurality of hardware devices.

21 . The method of claim 20 , wherein the plurality of hardware devices comprise a first hardware device of a first type and a second hardware device of a second type.

22 . A computer program product comprising a computer readable storage medium comprising computer readable program code embodied therewith, the computer readable program code comprising:
