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. A method, implemented at a computer system that is network connectable to one or more devices that can be tested for compliance with a UPnP™

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

protocol, the method comprising;

detecting devices that are connected to a common network with the computer system;

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

device architecture;

exposing a programmable interface for use in the development of programmatic test scripts that are external to the test tool such that programmatic test scripts can be developed without altering the test tool;

executing programmatic test scripts that are external to the test tool; and

determining if a device complies with a UPnP™

device architecture.

2. A computer program product for use in computer system that is network connectable to one or more devices that can be tested for compliance with a UPnP™

protocol, the computer program product comprising;

one or more computer readable media having stored thereon a test tool for testing devices for compliance with UPnP™

protocols, the test tool being configured to;

detect devices that are connected to a common network with the computer system;

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

device architecture;

expose a programmable interface for use in the development of programmatic test scripts that are external to the test tool such that programmatic test scripts can be developed without altering the test tool;

execute programmatic test scripts that are external to the test tool; and

determine if a device complies with a UPnP™

device architecture.

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

protocols, the computer system comprising;

one or more processors; and

one or more computer readable media having computer-executable instructions for implementing a 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.

4. The computer system as recited in claim 3, wherein the method further comprises:

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.

5. The computer system as recited in claim 3, wherein receiving selections of at least one device comprises receiving a network address that corresponds to a device.

6. The computer system as recited in claim 5, 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.

7. The computer system as recited in claim 3, wherein receiving selections of at least one device comprises receiving a device selection at a user-interface.

8. The computer system as recited in claim 3, wherein receiving selections of at least one device comprises receiving selections of a plurality of devices.

9. The computer system as recited in claim 3, 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 computer system as recited in claim 3, 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 computer system as recited in claim 3, 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 are to be executed to attempt to certify that the at least one device is UPnP™

compliant.

12. The computer system as recited in claim 3, 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 JScript script is to be executed to attempt to certify that the at least one device is UPnP™

compliant.

13. The computer system as recited in claim 3, 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 computer system as recited in claim 3, wherein the method further comprises:

validating that a selected script is a certification script.

15. The computer system as recited in claim 3, wherein executing the selected one or more scripts comprises a test harness and a scripting host interoperating to execute the selected one or more scripts.

16. The computer system as recited in claim 3, 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 computer system as recited in claim 3, wherein determining if the at least one selected device appropriately responded to the simulated functionality comprises determining if the device appropriately responded based at least in part on the UPnP™

protocol that is being tested.

18. The computer system as recited in claim 3, 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.

19. The computer system as recited in claim 3, wherein the method further comprises:

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.

20. The computer system as recited in claim 3, wherein the method further comprises:

configuring the selected one or more scripts to loop indefinitely prior to executing the selected one or more scripts;

receiving a stop signal; and

stopping execution of the selected one or more scripts in response to the stop signal.
