@drott - AFAIU we need to move these test cases from src/third_party/WebKit/LayoutTests/fast/css3-text/css3-text-decoration/ TO 

src/third_party/WebKit/LayoutTests/external/wpt/ folder .

But I didn't understand "marked as -visual... tests" .

Can you please let me know if this is what is needed and elaborate on "marked as -visual... tests."

Thanks,
Nikhil

As far as I understand WPT documentation, pixel tests need to follow the filename convention ...-visual.html
