Add promise rejection tracking tests #2388

domenic · 2015-11-30T22:25:43Z

Need a few pieces of help:

~~Running the allow-crossorigin and disallow-crossorigin tests fails for me locally because the {{ports[html][0]}} syntax from /cors/support.js is not getting preprocessed. Any ideas?~~works now, I forgot ?pipe=sub
I tried replacing setTimeout with t.step_timeout in disallow-crossorigin, but this caused the test to pass even when I changed the URL to be same-origin. I think that section of code probably just needs to be done better; review would be helpful.Fixed

I'd appreciate if review was done on GitHub, not Critic.

These tests were done in collaboration with @jeisinger. Apart from the abovementioned issues, they all pass in Chrome Canary with experimental web platform features enabled.

+      p.catch(function() {});
+    } catch (e) {
+      assert_unreached('attaching a handler should not throw an error');
+    }


Can use t.step(function() { p.catch(function() {}); } instead of try/catch

I pushed a fix for @zcorpan's review and also one for the troublesome issue I mentioned in the OP.

The only remaining potentially major item I can see is a global replacement of setTimeout with t.step_timeout. I'm happy to do that if people advise me it's a good idea. My experience is that they have strangely different semantics which scares me a bit.

zcorpan · 2015-12-01T17:47:25Z

Maybe best to ask @jgraham about step_timeout

domenic · 2016-08-28T16:43:38Z

Why close and delete my PR?

gsnedders · 2016-08-28T17:48:55Z

15:01 < aryehgregor> Um, I might have done something wrong by mistake.
15:01 < aryehgregor> I think I pushed to the wrong repo?

gsnedders · 2016-08-28T17:49:13Z

…and then I screw up and press "close and comment". This isn't our day. :\

Notifying @Ms2ger, @ayg, @gsnedders, @jdm, @jgraham, @sideshowbarker, @zcorpan, and @zqzhang. (Learn how reviewing works.)

These tests will be available shortly on w3c-test.org.

@jeisinger I realize we never landed this... do you have any idea why Chrome does not pass allow-crossorigin.html ?

add scriptEl.crossOrigin = 'anonymous'; - otherwise CORS won't be used.
