Assumptions

Familiar with UPnP™ v1 architecture and terminology

Interested in evaluating a device’s compliance against the UPnP™ standard

Pursuing the UPnP™ Logo

Overview

Certification Test Tool purpose

What is tested

Test capabilities

Using the tool and interpreting results

Purpose of Cert Tool

Drive the certification of UPnP™ devices

Execute device independent protocol tests against the UPnP™ v1 standard

Support device dependent syntax and semantic testing

What is Tested

Device-independent protocol tests

Device-specific syntax tests

New! Security Device tests

Device-specific semantic tests

Protocol Tests

Validate SSDP and HTTP packets and their sequence

Test the following stages: Addressing, Description, Discovery, Security, Control, Eventing

Execute regardless of device type

Syntax Tests

Actions to be tested for each device type are specified in an XML configuration file

Syntax tests are created by editing the <ServiceId>.SyntaxTests.XML file

Tests are run during the Control and Eventing test stages

Actions are invoked in the order in which they appear in the XML file

Device Security Tests

Available in test tool versions 1.4 and above

Device Security tests as part of the service syntax tests (3.*)

The test configuration file is ‘DeviceSecurity1.SyntaxTests.xml’

Semantic Tests

Verify specified output parameters, error conditions and events

Create semantic tests by editing the <ServiceId>.SemanticTests.XML file

Actions must be within the same service Results of one action cannot be used as

input parameters in another action

What is Not Tested

Does not test performance specifications

Does not certify device extensions external to the UPnP™ standard

Does not test incorrect inputs, boundary conditions

Does not test product capabilities

Tests on-the-wire interoperability

Test Environment

Test tool requires Windows XP

Run only one UPnP™ device and a single instance of the test tool on an isolated network

Turn off LAN connection settings (i.e. proxy settings) in Internet Options control panel on Windows XP

XML Configuration Files

<DeviceId>.xml Lists the implemented services and embedded devices

<ServiceId>.xml Lists the implemented Actions and State Variables

<ServiceId>.SyntaxTests.xml Lists the Action names and the ‘In’ arguments for each Action

<ServiceId>.SemanticTests.xml Lists the Action names, ‘In’ arguments and the expected ‘out’

arguments or error code.

Using XML Config Files

Working Committees Write the XML config files for standardized DCPs Distribute XML config files on the UIC web site

The test tool uses the XML files to verify Devices have all required services Services implement required Actions and State

Variables Devices respond correctly for each Action

invocation

Proprietary devices can be tested but require the respective XML config files

Test Tool UI

Select Test Options

Step Mode / Run Until Failure

Step Mode Pauses between each test Click the “Next” button to continue Useful when debugging a failure

Run Until Failure Pauses the test execution at the first failure

Interpreting the Test Log

Test Case 2.0.0.1 Passed

Test Case 2.1.0 Failed to RunFailure Reason :Precondition Failure - Unable to

Construct Device Discovery Message List.

Reason : Unable to Acquire Root Device Description Url.Badly formed Notify Alive Packets Header Value.

Reason : NT Header Value = SSDPBVT is Not Compliant to UDA V1.0

Helpful Hints

Review the test log for failure details

Use a network sniffer UPnP™ parser available for Microsoft Network

Monitor Useful for reporting problems

Use Step Mode to help isolate an issue

Refer to the Test Tool User documentation for descriptions of each test case

Helpful Hints Continued

A full certification pass takes about 25 minutes to complete

For testing purposes, set the CACHE-CONTROL in the device to be less than 60 for SSDP alive notifications

In your final device implementation, set the CACHE-CONTROL according to UDA recommendations
