Comment on attachment 97761 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=97761&action=review Thank you for doing this! Unfortunately I'm not an expert in this area. So I'd like to have some prep review before calling the experts ;-) That being said, the test strategy itself looks fine. > LayoutTests/fast/dynamic/hover-before-position-after-style-change.html:1 > +<!DOCTYPE html> We need <html> > LayoutTests/fast/dynamic/hover-before-position-after-style-change.html:9 > + function getElementTop(elementId) { Webkit tests usually have one <script> block. You can use layoutTestcontroller.waitUntilDone() and notifyDone() for keep DRT running during the exercise. > LayoutTests/fast/dynamic/hover-before-position-after-style-change.html:26 > + if (window.layoutTestController) { Could you make this test runnable without layoutTestController? WebKit devs prefer to keep tests runnable in Safari (or other browsers) as possible. An idiom is: if (!window.layoutTestController) return; inside a test function. > Source/WebCore/ChangeLog:8 > + https://bugs.webkit.org/show_bug.cgi?id=56401 Please follow the standard changelog format. - You need a bug summary line before the URL line - The detailed description should come after the URL.

The test passes if you see a "PASS" below. "PASS" is a kind of convention So you don't need to mention it explicitly. Instead of that, manual testing instruction would be preferable here. > LayoutTests/fast/dynamic/hover-before-position-after-style-change.html:20 > + function getElementTop(elementId) { "{" should be placed on the next line. The coding convention is almost same as one of c++. (Unfortunately, check-webkit-style doesn't check JavaScript inside HTML...)

Could you make this more straightforward? I guess we can split it into - a function to emulate the mouse move - another function to check the result. Then |fromMouseOver| would be no longer required.

The test that fails in debug is svg/custom/crash-textPath-attributes.html. An assertion: ASSERT(newNode->firstChild()); is hit in RenderCounter::makeCounterNode causing the test to fail.
