+// CompositorFloatKeyframe is a plain struct, so we just create an == operator

[jbroman, 2016/05/27 14:52:55]

Not introduced in this CL, but obligatory warning: this has the potential to
cause ODR issues down the road if operator== or PrintTo for
CompositorFloatKeyframe are ever wanted elsewhere. You can still have the print
function only compiled into unit tests; see e.g. platform/geometry/FloatPoint.h
+ platform/testing/GeometryPrinters.{h,cpp}.

[jbroman, 2016/05/27 14:52:55]

Here and elsewhere, you want ASSERT_EQ, not DCHECK_EQ. While Blink's ASSERT is
going away in favour of DCHECK, ASSERT_EQ is from gtest and is still good (marks
the test as failed instead of crashing the test runner, for instance).

[loyso (OOO), 2016/05/31 02:20:39]

Partly done.

It looks like it doesn't work in function with return values.

error: no viable conversion from returned value of type 'void' to function
return type 'std::unique_ptr<CcAnimationForTesting>'
