Could you name test file as file-accessing-entries.html?
We're now arranging test case file name as ${inputType}-*.html.
Thanks for your cooperation!

You don't need to put "console" markup by yourself.
js-test-pre.js creates it for you.

You may not need to set successfullyParse by yourself.
Function  isSuccessfullyParsed() sets it to true for your.

The code change looks ok.

This test doesn't work on platforms without ENABLE_FILE_SYSTEM. So I think the test should be put into fast/filesystem/.

Ok... I was a bit separated since it's also a form test too but I moved it under fast/filesystem.
We have one more .webkitEntries test in fast/forms/file.  Should we move it (in another change) too then?
