This is the runtime test portion of the PR stack, it's not changed particularly much from the last iteration of the PR stack other than 2 additional tests for the new "features" added. I believe previously it was already signed off and reviewed by @skatrak @TIFitis so if you're both still happy with this PRs current state, please do feel fee to approve again or otherwise leave further comments! :-) Incredibly sorry for the extra work.
