Very cool.

> This has to be manually set (and not built from the file) because TestRunner is not always going through ObjC flows, and I didn't want to complicate our testing code with calling ObjC icon APIs from C++ code.

Can you elaborate on this? This is quite different from the approach I had in mind, but I don't know if there is some obstacle.

I thought that we could add a testRunner or Internals function that creates a FileList object out of a list of paths, its invocation would be very similar to beginDragWithFiles(). Once there is a FileList object, it can be simply assigned to input.files in JavaScript, and then the engine takes care of figuring out the icon.

So the test would just do 

var file1 = document.getElementById('file1');
file1.files = testRunner.createFileList(["resources/something.txt"]);
file1.value = '';
