1023516 - (srcset-tests) Add tests for basic <img srcset>

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[John Schoenick [:johns]]

This tracks adding tests for the basic (non-sizes) <img srcset> syntax

Syntax tests for the newer parse algorithm will be covered by Bug 1023514

Attachment: Basic image srcset reftests

Reftests to make sure the features of srcset behave as they should. This is only testing srcset, not sizes nor <picture>, which are bug 1023519

Bug 1037643 has the tests for mutating img, removing/adding srcset, etc.
Bug 1023514 will cover ensuring we parse srcset properly

Let me know if you can think of anything else we should have coverage for before pref'ing this on

I should mention that the tests differing only in scale factor are script generated duplicates, e.g.

> image-srcset-basic-selection-0.1x.html
> image-srcset-basic-selection-2x.html
> image-srcset-basic-selection-0.5x.html
> image-srcset-basic-selection-0.6x.html
> image-srcset-basic-selection-1.5x.html
> image-srcset-basic-selection-1x.html

Will all be identical outside of scale factor, which has to be specified on a per-file basis for the reftest harness
