Notifying @jdm and @youennf. (Learn how reviewing works.)

[annevk]

I'm not sure about the above three lines being the correct way to do this. I asked in #whatwg but nobody was around to answer.

[mkruisselbrink]

You probably want that to be return Promise.all([promise_rejects(...), promise_rejects(...), promise_rejects(...)])?

[annevk]

Does that work? I cannot really find any documentation about how this is supposed to work. @jgraham?

[jdm]

Yeah, the callback to promise_test needs to return a single promise that encompasses all asynchronous behaviour. Promise.all is what you want here.

[annevk]

Thanks, fixed.

@ricea does this look good now? @jdm?

[jdm]

Yep!

[ricea]

Looks good to me.
