  10. Test Tools Summary • Easy to use test tools are available now • They cover a wide range of test areas • XPS and PrintTicket conformance tools are critically important

  11. XPS Conformance And isXPS Justin SloneTest Development EngineerDigital Documents Platform and Solutions

  12. XPS Conformance • XPS conformance enabled through • Strict standard, strict test tools, strict implementations • isXPS.exe (codenamed isReach) is a strict test tool designed and developed by Microsoft • Assists in determining if an XPS document conforms to the XPS specification

  13. XPS Conformance Authority • In order of authority • The XML Paper Specification • The XPS conformance test provided by Microsoft • The WPF XPS Viewer

  14. isXPS Overview • Goals of isXPS • Verify Open Packaging Conventions (OPC) conformance • Verify XPS Document conformance • Provide detailed error information • Requirements to run isXPS.exe • .NET 2.0 • WPF

  15. XPS Document Framework DocThumb.jpg Legend Resource Parts – OPC Parts – XPS Parts – Conceptual Parts – Relationships – Markup References – Package Root _rels/.rels FixDocSeq.fdseq Image_1.jpg _rels/FixDocSeq.fdseq.rels _rels/.rels FixDoc.fdoc 1.fpage 1.fpage _rels/1.fpage.rels Package Root Font_0.ttf Image_1.jpg

  16. Conformance Checks DocThumb.jpg • Pre-validation • Validate font and image parts • OPC validation • Validate relationship markup • Process package relationships • Digital Signatures • Core Properties • Thumbnails • Etc Package Root _rels/.rels FixDocSeq.fdseq _rels/FixDocSeq.fdseq.rels FixDoc.fdoc 1.fpage _rels/1.fpage.rels Font_0.ttf Image_1.jpg

  17. Conformance Checks DocThumb.jpg • XPS validation • Start from fixedrepresentationrelationship • Validate markup of FixDocSeq • Follow <DocumentReference> to FixedDocs • Validate markup of FixDoc • Follow <PageContent> to FixedPages • Validate markup of 1.fpage • Discover Resource Parts Package Root _rels/.rels FixDocSeq.fdseq _rels/FixDocSeq.fdseq.rels FixDoc.fdoc 1.fpage _rels/1.fpage.rels Font_0.ttf Image_1.jpg

  18. Conformance Checks DocThumb.jpg • Markup references • Font references • Image references • ICC profile references • Resource dictionaries • Processing similar to a FixedPage • Process relationships from FixedPage part • Confirm that there are matching required-resource relationships to all markup referenced parts Package Root _rels/.rels FixDocSeq.fdseq _rels/FixDocSeq.fdseq.rels FixDoc.fdoc 1.fpage _rels/1.fpage.rels Font_0.ttf Image_1.jpg

  19. Most Used Switches -f=<FilePattern> The file on which to perform the validation e.g. file.xps or *.xps /s Apply FilePattern to all subdirectories -logger:<LogType> The logger to use (File, Console, WTT) -logfile:<LogFile> The log file to write to when using the File logger Default logfile is “isXPSLog.txt” Most Common Usage

  20. isXPS Logfile Sample Error Log Rollup +Start Test: /Documents/1/Pages/3.fpage Markup Info: Validating Markup of Part 3.fpage using target namespace … Fail: Markup is not Conformant: Number of errors: 1 Info: Error #1: At position (4,93) Message: The ‘Stretch’ attribute is not declared. -End Test: /Documents/1/Pages/3.fpage Markup Result: Fail -End Test: Processing file: C:\Exercise_1.1.xps Result: Fail -End Test: isXPS Result: Fail *********Log Rollup************************************************ TestName: isXPS PassRate: 81% Pass: 18 Warn: 0 Fail: 4 Block: 0 ******************************************************************* Result: Fail

  21. isXPS Takeaway • Use isXPS.exe for easy OPC and XPS conformance validation • Detailed error information helps quickly isolate bugs • Visit the XPS Printing hands on lab • XPS Testing and Conformance lab • Find isXPS (named isReach) in Beta 2 WDK and SDK

  22. XPS Test Strategies Jim ZuberXPS Test ArchitectQualityLogic, Inc.

  23. QualityLogic, Inc. • De facto standard test tool provider to printer industry for 20 years • Released XPS test suites to the industry in late 2005 • Provided XPS training to over 20 XPS early adopter companies • Just completed a set of XPS analysis and debugging utilities

  24. Topics • XPS Characteristics • Keys to Interoperability • Testing Challenges • XPS Consumer Analysis

  25. XPS Characteristics • Standards based • XML, JPG, TIFF, ICC, Etc • Clear specifications • Example code • Clarifications • Baseline reference • XPS Viewer

  26. XPS Characteristics • A very efficient set of drawing primitives • Paths can contain arcs, lines, and Bezier curves • Paths and Glyphs can be painted with brushes • Common properties control clipping, transforms, and opacity

  27. XPS Characteristics • Simple syntax • Elements and attributes • Low complexity • Human readable • A very testable technology!

  28. Keys To XPS Interoperability • Clean XPS markup generated by XPS producers • IsXPS • PTConform • Conformant XPS consumers • Functional Test suites • Comprehensive Test suites • Minimize specification ambiguities • Xpsinfo @ microsoft.com

  29. Keys To XPS Interoperability • Application compatibility testing of XPS consumers • All print paths • Key applications • Diversity of producers • Conversion programs • Strict de facto standard XPS consumer • WPF XPS Viewer • Practical arbiter of “is it right”

  30. XPS Testing Challenges • Clarifications to specification still emerging • No hardcopy reference target • Page comparison • Practical implementation limits • Few unique XPS producers • Interoperability testing • Usage models

  31. XPS Testing Challenges • Interactions between XPS markup and PrintTickets • Complex scenarios with VisualBrush • New image file format • WMPhoto • XPS analysis • Interleaved files

  32. XPS Analysis Tools • Microsoft • XPS Viewer • IsXPS • PTConform • XamlPad • QualityLogic • StatGen • PrintTicketer • XPS Parts Assembler

  33. XPS Consumer Analysis • Identify the symptoms • Is it a crash or a visual anomaly? • Do you get an error report? • Try viewing the file in the XPS Viewer • Does the same error occur? • Get a big picture view • Unzip – What parts are in the package? • Statistics – Stream sequence and element usage

  34. XPS Consumer Analysis • Schema Validation • Microsoft’s isXPS program will quickly validate the schema, as well as relationships and resource file integrity • Test Code Fragments • If problem also occurs in XPS Viewer, cut and paste suspect markup into XamlPad to isolate problem

  35. XPS Consumer Analysis • Problem occurs only in device under test • Use ZIP utility and XML Editor to modify the XPS markup in the container • Reduce to smallest number of XPS elements that reproduce problem • Suspect PrintTickets • Extract PrintTicket part and run PTConform to find syntax problems • Use PrintTicket editor to modify PrintTicket settings inside container to isolate problems

  36. Summary • XPS has the potential to quickly achieve a high degree of interoperability • Tools are available NOW to start testing and debugging your XPS implementations

  37. Call To Action • Familiarize yourself with XPS and PrintTicket specifications and XPSDrv technology in particular • Use Microsoft test tools to validate your implementations • Be ultra strict as far as XPS and PrintTicket conformance is concerned • Test for compatibility now! • Test the GDI Print Path, XPS Print Path, and compatibility paths • Test your company’s XPSDrv and XPS-capable printers • Report problems immediately • Invest in testing – it pays out!

  38. Call To Action • Understand your company logo goals and review new logo requirements • Basic and Premium • At WinHEC • Practice driver dev and testing skills in XPS Printing hands on labs • Ask the Experts at lunch today • Visit the Microsoft Pavilion to see XPS demos • Attend related sessions • PRI050 Inside Printer Installation on Windows Vista • PRI039 Using the Windows Color System in Device Drivers • PRI102 Using XPSDrv Print Drivers to Extend Windows Print Functionality • PRI019 Developing XPSDrv Print Drivers • PRI115 Windows Media Photo: A New Format for End-to-End Digital Imaging
