Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:

[PATCH v3 3/7] jscript: Throw proper error in Object methods with non-objects args.

[Gabriel Ivăncescu]

According to the ES6 spec, they don't throw anymore (compared to ES5),
but native IE seems to not follow it here and throws anyway.

[PATCH v3 4/7] mshtml/tests: Test for RegExp.prototype.toString with non-regexp.

[Gabriel Ivăncescu]

According to the ES6 spec, it should work in generic way for objects exposing
"source" and "flags", but native IE seems to not follow it here and throws.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be

Tested in the next patch (we use the test_own_data_prop_desc helper to
avoid redundancy, which also checks enumerable).

They look mostly good, but it looks like TestBot is not happy with those 
tests. Also, is there a reason to use 
Object.prototype.hasOwnProperty.call(s,"...") instead of simply 
s.hasOwnProperty(s, "...")?

Thanks,

Jacek

That looks like a bug in Windows 8's mshtml jscript engine, I can't 
explain it in any other way (and why it happens only on Windows 8 VMs). 
Should I leave the test out? I don't know how to mark it as broken for 
Windows-only in js tests.

And sorry about the Object.prototype.hasOwnProperty, it's just a habit 
when I write tests so I know exactly what it's tested (bypassing any 
overrides in the prototype chain). There's no other reason. I know I 
changed it before, but I either keep forgetting to change them all or 
keep rewriting it :-/
