Test Coverage for SVG Tiny 1.2 Chapter 12: Multimedia

 # is an assertion or feature that is partially or not covered in the test suite

12.1 Media Elements

# test that the default event-base element for all SVG Media elements is the element itself.

12.1.1 Media timeline and document timeline

# test timelineBegin="OnLoad" with video. Start with a large SVG file ( perhaps using many base64-encoded  images ) which has a video element at the end. Video frame displayed should be at video playback time 0. * test timelineBegin="OnStart" with video. Start with a large SVG file ( perhaps using many base64-encoded  images ) which has a video element at the end. Video frame displayed should be at video playback time > 0.


# test timelineBegin="OnLoad" with video that has syncBehavior="independent". Start with a large SVG file  ( perhaps using many base64-encoded images ) which has a video element at the end.  Video frame displayed should be at video playback time 0.


# test timelineBegin="OnStart" with video that has syncBehavior="independent". Start with a large SVG file  ( perhaps using many base64-encoded images ) which has a video element at the end.  Video frame displayed should be at video playback time 0.



12.1.2 Media availability

- determining when media is 'available' depends on media type and is not normative - may be hard to test

12.1.3 Platform limits

- has been identified as an issue - which media types to support in the testsuite.

12.2 The 'audio' element

 test that audio behaves reasonably when xlink:href is not an audio stream (image, video, "", etc).


 test that xlink:href animation on audio changes media and, if media playback time can be controlled,  the timeline is reset to zero.


 tests for SMIL attribute begin.


 tests for SMIL attribute dur.


 tests for SMIL attribute end.


# tests for SMIL attribute min.


# tests for SMIL attribute max.


# tests for SMIL attribute restart.


 tests for SMIL attribute repeatCount.


 tests for SMIL attribute repeatDur.


# tests for SMIL attribute fill.

12.3 The 'video' element

 test that video behaves reasonably when xlink:href is not a video stream (image, audio, "", etc).


 test that xlink:href animation on video changes media and, if media playback time can be controlled,  the timeline is reset to zero.


 tests for SMIL attribute begin.


tests for SMIL attribute dur.


 tests for SMIL attribute end.


# tests for SMIL attribute min.


# tests for SMIL attribute max.


# tests for SMIL attribute restart.


 tests for SMIL attribute repeatCount.


# tests for SMIL attribute repeatDur.


 tests for SMIL attribute fill.


 tests for transformBehavior = pinned.
 tests for transformBehavior = pinned90.
 tests for transformBehavior = pinned180.
 tests for transformBehavior = pinned270.
 tests for transformBehavior = geometric including preserveAspectRatio, height, width attributes.


# tests for transformBehavior = geometric including viewport-fill, viewport-fill-opacity attributes.


# test for focusability.


# test for initialVisibility.


# test for overlay.


# test for http://www.w3.org/Graphics/SVG/feature/1.2/#Video in switch.


 test for http://www.w3.org/Graphics/SVG/feature/1.2/#TransformedVideo in switch.


# test for http://www.w3.org/Graphics/SVG/feature/1.2/#ComposedVideo.

12.4 The 'animation' element

 test that animation element behaves reasonably when xlink:href is not a SVG file (image, video, "", etc).


 test that xlink:href animation on animation element changes resource and the timeline is reset to zero.


 tests for SMIL attribute begin.
 tests for SMIL attribute dur.
 tests for SMIL attribute end.
 tests for SMIL attribute min.
 tests for SMIL attribute max.
 tests for SMIL attribute restart.
 tests for SMIL attribute repeatCount.
 tests for SMIL attribute repeatDur.
 tests for SMIL attribute fill.


 tests for viewport-fill, viewport-fill-opacity and preserveAspectRatio.


# test that there is no inheritance of properties into the referenced animation.


 test for focusability.


  test for initialVisibility

12.5 The audio-level property

# test audio-level property on audio, video, animation and g elements
 test that a value > 1.0 increases audio level
 test that a value < 1.0 decreases audio level
 test that if the element has an element volume of 0, then the output signal must be inaudible
 test that if the element has an element volume of 1, then the output signal must be at the system volume level - this may be difficult to test
 test animation of audio-level property

12.6 Attributes for runtime synchronization

- test on audio, video, animation elements


- would be nice to have streaming video server (Darwin?) which could produce delays in streaming the content.


- can pause timelines by using uDOM methods pauseElement and resumeElement


# test syncBehavior="locked". SVG file will have a media element which has syncBehavior="locked". Delay media element on specific user interaction - media should skip to syncronize with document time.


# test syncBehavior="locked" and with a syncTolerance > 0. SVG file will have a media element which  has syncBehavior="locked" and syncTolerance > 0. Delay media element on specific user interaction -  media should pause until given syncTolerance has elapsed and then jump to document time. The media element should then pause until syncTolerance has elapsed and repeat as needed.


# test syncBehavior="canSlip". SVG file will have a media element which has syncBehavior="canSlip". Delay media element on specific user interaction - media should pause while document time continues.


# test syncMaster="true" on media element. SVG file will have a media element which has  syncMaster="true". Document time should be paused until the media timeline is advanced. Pausing the media element will pause the document timeline.


# test syncBehavior="locked" and syncMaster="true" and syncTolerance > 0. SVG file will have a media  element which has syncMaster="true". Document will conatin a second media element which has syncBehavior="locked" and syncTolerance > 0. All timelines should be paused until the media timeline is advanced. Pausing the media element will pause the document timeline immediately and the seconded media timeline once syncTolerance has elapsed.


#' test syncBehavior="canSlip" and syncMaster="true". SVG file will have a media  element which has syncMaster="true". Document will conatin a second media element which has syncBehavior="canSlip". The document timeline should be paused until the media timeline is advanced. The seconded media timeline should not be paused.


# test syncToleranceDefault and syncBehaviorDefault.


- many more combinations of each media element, which timeline is paused, is syncMaster, etc.

12.7 The 'initialVisibility' attribute

- covered in video and animation sections
