Description Marcos Caceres 2012-12-03 15:27:45 UTC 
+++ This bug was initially created as a clone of Bug #20173 +++

The img@srcset spec lacks a script-based means to determine what resource the image element is displaying (if any). The use case for this is for testing and generally for a developer to know what is going on.

For the developer, the console tools are probably a better way of helping.

For testing, wouldn't checking the rendered result be better? What are we testing exactly, and how?
