This page aims at summarizing all the UA test cases covering the syntax, semantics, and units of the three dimensions defined in the Media Fragment URI specification. The temporal test cases have been partially defined during the 5th face-to-face meeting, see also http://www.w3.org/2008/WebVideo/Fragments/meetings/2010-03-09-f2f_ghent/
For the temporal test cases, we introduce the following definitions:

| Test case type |
| TC | Description | Media Fragment | Expected HTTP request | Expected visual output | Comment | Status |
|---|---|---|---|---|---|---|
| TC0001-UA | #t=, | t=, | OR | Playback of the entire media resource | Syntax error, not allowed according to the ABNF. The media fragment is ignored. | approved |
| TC0002-UA | #t=a,a and a >= 0 | t=3,3 | OR | Playback of the entire media resource | Invalid semantics: start must be smaller than end. The media fragment is ignored. | approved |
| TC0003-UA | #t=a,b and a > b | t=7,3 | OR | Playback of the entire media resource | Invalid semantics: the requested interval's start is beyond its end. The media fragment is ignored. | approved |
| TC0004-UA | #t=a,b and a = 0, b = e | t=0,9.97 | OR OR OR | Playback of the entire media resource | The media is requested from 0 to e. | approved |

| TC0014-UA | #t=a with a >= e | t=15 | OR OR | UA seeks to the end of the media resource. | The request lies beyond the end of the resource. If the UA knows the duration of the resource, it seeks to the end of the media resource. Otherwise, the UA will send an (out-of-range) HTTP request with an 'include-setup' in order to setup its decoding pipeline. | approved |
| TC0015-UA | #t=,b and b > 0, b <= e | t=,7 | OR OR OR OR | Playback from the beginning to 7 seconds | Equivalent to #t=0,b. The media is requested from 0 to b. | approved |
