runtime error should throw properly

[leobalter]

This test is relying on $DONE to throw an error. I wonder if the test should have a flags: [async] frontmatter flag or also just throw a custom error instead. Otherwise, there's nothing telling the runner to wait.

https://github.com/bterlson/test262-harness/blob/4fb2a88f95daa01f8c34d6ec49e26e77079bb722/test/collateral/asyncNegative.js#L11

I found this because I'm getting a failure for this test.

[leobalter]

The same flags: [async] should go to the async.js file in the same folder.

[leobalter]

btw, the error is coming from eshost 3.5.0, it doesn't fail on eshost 3.4.3.

[bterlson]

Async flag seems appropriate here, but I'm intrigued about the eshost 3.5 regression/change of behavior.

[leobalter]

this might need fetching each commit on eshost since 3.4.3 to find the cause. I'm not familiar with it's code and I suspect my time won't be the best fit to solve it. I'm starting a PTO for ~10 days.

I can try to do a git bisect

[leobalter]

I did a git bisect, and also found the exact bug happening by forcing installing eshost@3.4.3 vs 3.5.0

I wonder if the test should have a flags: [async]

Does not correct the issue

[rwaldron]

lol...

setTimeout is not defined

[bterlson]

@rwaldron are you investigating? I can take this one if you like.

[rwaldron]

I found it and fixed it.

[bterlson]

Alright! Excellent.
