I think this is a breaking (and unnecessary) change 😃
Why not set dstAttr[key] for class and style ?

@gkalpak - I don't believe this is a BC. The previous behaviour was not to set distAttr for class and style, so doing so would actually be a BC.

Wow, you are right, it didn't. Any idea why?
It seems like an oversight (bug?)...

Anyway, this is consistent, so no harm 😃

dstAttr[key] = srcAttr[key];

Aren't $compile and $rootScope already available inside the top-level `describe's scope ?
Why is everyone injecting it ? 😛

I just tried removing it - injection seems necessary

element = $compile(
'<div><div log-attrs replace class="myLog"></div><div>')($rootScope);
var div = element.find('div');
expect(div.attr('class')).toBe('myLog log');
expect(attrs.class).toBe('myLog log');
});
});

I would add a test for style as well, since it is a different code path.

Really? Both are handled by the if (!dst[key]) { before the src loop.

There are different if/else branhes for each. Most importantly, the one uses safeAddClass(...) and the other $element.attr('style', ...). We need to make sure that whatever these code paths do (which are skipped when dst[key] is trythy, has already been done in the previous loop (where we use dst.$set(...)).

try {
$compile('<div><span replace class="replace"></span></div>');
