Why || '0'?

[dcheng, 2015/10/15 06:06:53]

Ditto, why || '0'? We can test if the return value is undefined if that's what
we're trying to check for.

[lazyboy, 2015/10/15 16:56:38]

Technically margin of 0 can come from Number(0) and undefined.
This keeps things simple, otherwise I'd have to check for undefined first, then
if not undefined check for int 0.

[dcheng, 2015/10/15 22:07:46]

I don't think I follow. In the test, it should be deterministic whether it's '0'
or undefined, right?

[dcheng, 2015/10/15 22:20:17]

Also... since this is a unit test, maybe just use
HTMLBodyElement::getIntegralAttribute() directly rather than going through JS?

Sorry, I really should have noticed this earlier.

[lazyboy, 2015/10/15 23:00:52]

Yes, it is deterministic in this test. What I wanted to do was not
depend on what was returned null/undefined/0.

[lazyboy, 2015/10/15 23:00:52]

That is just cool! Thanks.
