1523562 [wpt PR 15061] - Worker: Fix wpt/workers/semantics/run-a-worker/003.html for shared workers, a=testonly
Automatic update from web-platform-tests
Worker: Fix wpt/workers/semantics/run-a-worker/003.html for shared workers
Before this CL, the test expects that a 404 failure on shared worker script
fetch doesn't fire an error event. However, this doesn't obey the HTML spec
(see below), and actually Chrome and Firefox fail the test [1]. Note that
Edge and Safari haven't been implemented shared workers.
This CL changes the test to expect that the failure fires an error event.
<HTML spec from [2]>
12. Obtain script by switching on the value of options's type member:
- "classic": Fetch a classic worker script given url, outside settings,
destination, and inside settings.
(...snip...)
If the algorithm asynchronously completes with null, then:
- Queue a task to fire an event named error at worker.
- Run the environment discarding steps for inside settings.
- Return.
</HTML spec>
<Fetch spec from [3]>
To fetch a classic worker script given a url, a fetch client settings
object, a destination, and a script settings object, run these steps.
The algorithm will asynchronously complete with either null (on failure) or
a new classic script (on success).
(...snip...)
4. If response's type is "error", or response's status is not an ok
status, asynchronously complete this algorithm with null, and abort
these steps.
</Fetch spec>
