[webkit-help] Testing modifications to Webkit efficiently

[Lay Kuan Loh]

Hi all,

Newcomer to webkit here.

I am trying to modify WebKit <https://webkit.org/> for my own purposes. I
do not plan to ship my modifications to the official codebase.

How would I check that the changes I make to WebKit did not break anything?
For instance, I am making changes to the file
WebKit/Source/WebCore/dom/Element.cpp and would like to test them
incrementally.
