Are all of these includes needed? SimDisplayItemList.h looks unused, at least.

[esprehn, 2017/02/03 22:31:10]

BeginFrame() returns an instance of it and it's forward declared. I should
probably fix that to not forward declare it since it's annoying to include it in
every test

+bool hasSelectorForIdInShadow(Element* host, const AtomicString& id) {
+  DCHECK(host);

[rune, 2017/01/20 11:41:16]

Don't we typically use ASSERT_TRUE instead of DCHECK in tests?

All tests below access host-> before calling these methods, though.

[esprehn, 2017/02/03 22:31:10]

This was a support method so an assert looked funny.

Acknowledged.

ShadowDOMVTest -> ShadowDOMV0Test ?

Woops yeah
