Abstract

The present invention extends to methods, systems, and computer program products for enhanced Universal Plug and Play (“UPnP™”) compliance testing. A control point (e.g., a computer system) and one or more devices (e.g., printers, wireless gateways, etc.) are network connectable (or are connected) to a common network. The control point includes a test tool that can execute scripts to simulate UPnP™ functionality. Using scripts allows more flexible and programmatic UPnP™ compliance testing. Multiple devices can be selected for testing thereby reducing the burden associated with individually testing devices on an isolated network. Test logs can be secured using digital signatures to reduce the likelihood of test logs being intentionally or inadvertently altered prior to being received at a certification authority.

Claims

1. At a computer system that is network connectable to one or more devices that can be tested for compliance with a UPnP™

protocol, a method for testing at least one device from among the one or more devices for compliance with a UPnP™

protocol, the method comprising;

receiving selections of at least one device that is to be tested for compliance with the UPnP™

protocol;

receiving selections of one or more scripts that are to be executed to test the at least one device for compliance with the UPnP™

protocol;

executing the selected one or more scripts, execution of the selection one or more scripts causing electronic messages, which simulate the functionality of the UPnP™

protocol, to be sent to the at least one device; and

determining if the at least one selected device appropriately responded to the simulated functionality.

2. The method as recited in claim 1, further comprising:

the computer system detecting that the computer system and the one or more devices are connected to a common network; and

presenting a list of the one or more devices at a user-interface.

3. The method as recited in claim 1, wherein receiving selections of at least one device comprises receiving a selection of at least one device that was identified by the computer system.

4. The method as recited in claim 1, wherein receiving selections of at least one device comprises receiving a network address that corresponds to a device.

5. The method as recited in claim 4, wherein receiving a network address that corresponds to a device comprises receiving a network address that corresponds to a device that is on a different network segment than the computer system.

6. The method as recited in claim 5, wherein receiving a network address that corresponds to a device that is on a different network segment than the computer system comprises receiving a network address that corresponds to a device that is separated from the computer system by a WAN link.

7. The method as recited in claim 1, wherein receiving selections of at least one device comprises receiving a device selection at a user-interface.

8. The method as recited in claim 1, wherein receiving selections of at least one device comprises receiving selections of a plurality of devices.

9. The method as recited in claim 1, wherein receiving a selection of one or more scripts that are to be executed to test the at least one device comprises receiving a selection of one or more scripts that are stored external to a test tool that is to be used to execute the scripts.

10. The method as recited in claim 1, wherein receiving a selection of one or more scripts that are to be executed to test the at least one device comprises receiving a selection of one or more scripts at a user-interface.

11. The method as recited in claim 1, wherein receiving a selection of one or more scripts that are to be executed to test the at least one device comprises receiving a selection that one or more certification scripts arc to be executed to attempt to certify that the at least one device is UPnP™

compliant.

12. The method as recited in claim 1, wherein the receiving a selection of one or more scripts that are to be executed to test the at least one device comprises receiving a selection that a JScript script is to be executed to attempt to certify that the at least one device is UPnP™

compliant.

13. The method as recited in claim 1, wherein receiving a selection of one or more scripts that are to be executed to test the at least one device comprises receiving a selection that a VBcript script is to be executed to attempt to certify that the at least one device is UPnP™

compliant.

14. The method as recited in claim 1, further comprising:

validating that a selected script is a certification script.

15. The method as recited in claim 1, wherein executing the selected one or more scripts comprises test harness and a scripting host interoperating to execute the selected one or more scripts.

16. The method as recited in claim, 1 wherein executing the selected one or more scripts comprises executing a selected script to test a device for compliance with one or more of an UPnP™

addressing protocol, a UPnP™

discovery protocol, a UPnP™

description protocol, a UPnP™

control protocol, and a UPnP™

eventing protocol.

17. The method as recited in claim 1, wherein executing the selected one or more scripts comprises executing a selected script to test a device that is on a different network segment than the computer system.

18. The method as recited in claim 17, wherein executing a selected script to test a device that is on a different network segment than the computer system comprises executing a selected script to test a device that is connected to the Internet.

19. The method as recited in claim 1, wherein determining if the at least one selected device appropriately responded to the simulated functionality comprises determining the device appropriately responded based at least in part of the UPnP™

protocol that is being tested.

20. The method as recited in claim 19, wherein determining if the device appropriately responded based at least in part onto UPnP™

protocol that is being tested comprises determining if the device appropriately responded based at least in part on the UPnP™

protocol the UPnP™

protocol being selected from among a UPnP™

addressing protocol, a UPnP™

discovery protocol, a UPnP™

description protocol, a UPnP™

control protocol, and an UPnP™

eventing protocol.

21. The method as recited in claim 1, wherein determining if the at least one selected device appropriately responded to the simulated functionality comprises determining if device responses indicate that a device complies with UPnP™

Device Architecture version 1 or UPnP™

Device Architecture version 2.

22. The method as recited in claim 1, further comprising:

storing the results of the selected one or more tests in a secure test log; and

submitting the secure test log to a certification authority.

23. The method as recited in claim 1, further comprising:
