http://www.w3c-test.org/workers/WorkerGlobalScope_importScripts_NetworkErr.htm tests for a NetworkError.

Checked in as WHATWG revision r8874.
Check-in comment: Clarify what 'failed' means in importScripts().

Comment 3 Anne 2015-01-07 08:51:12 UTC 
That's almost certainly not what's implemented though. HTTP 404 error is executed for scripts. Only actual network errors cause failure.
Comment 4 Ian 'Hixie' Hickson 2015-01-08 18:45:16 UTC 
We should fix that for importScripts(), unless someone relies on it.
Comment 5 Anne 2015-01-09 06:27:16 UTC 
Why? What's the advantage? And what set of status codes should we accept instead post-redirect? 200-299?
Comment 6 Ian 'Hixie' Hickson 2015-01-09 23:35:06 UTC 
The advantage is just to reduce the amount of script that gets executed when the author isn't expecting script to be executed. Just like honouring MIME types or magic signatures.
