Are you accepting questions about your CM6 repo?
I didn’t find instructions for building and running the tests in there so I did a little poking around. Also I didn’t know much about TypeScript or rollup before seeing your repo using them.
I found the following seems to build view/test/test_built.js but there are many options to rollup so maybe I’m missing something important.
rollup -c rollup.view-tests.config.js --format iife
Changing directory to view/test and loading some npm modules at that level then let me start a simple file server from that directory and low and beyond, a beautiful test result page appeared in a new Chrome window on my mac showing 112 or 113 tests passed.
This was your only announcement for CM6 and the git log shows you are very busy working this new version so perhaps you don’t need or want anyone running tests with browsers on a mac yet (am on OSX 10.13.6). I would open new discussions if you are interested in the Chrome investigation and then possible Safari investigations on the same OS. I hesitated even bringing this up but when all but one unit test is passing, it made me think you like to keep your unit tests passing on at least some subset of platforms while you are developing.
