Have started to work on porting parts of the Faces 4.0 #TCKs to Selenium. The reason was, I have rewritten the #MyFaces codebase to #Typescript with a compile target of Ecmascript 2015 and newer Dom standards, and HTMLUnit now utterly is lost with the generated code (HTMLUnit is still stuck on ES5 with some things for ES6 implemented)
So moving the codebase now to Selenium Webdrivers and headless chrome.
About 30 tests already are ported and running...
