This is test only.

we are going to check which tests pass - and then disable all that do not to detect breakages from this point on. correcting the test suite issue across the board is a months long effort - that doesn't align with 2017 plans.

Add-on SDK is no longer supported so resolving bugs as INCOMPLETE
