before Systemjs/Jspm I was using a lot requirejs, for that time I remember a really nice test-framework https://github.com/testem/testem , no idea how it is the status nowadays…
I am guessing if you are still using karma with jspm, I have read https://medium.com/@capajj/why-it-is-foolish-to-use-karma-with-jspm-3af9ebd02af that wasn't very happy with it.
I am trying to get an idea how it is the state of the art today. So Can I ask you about your most recent opinion about testing with jspm? whether you have changed your mind.
You know, I am trying to find the most recent opinions about how to do test across different browsers smoothly with jspm,
Thanks a lot for sharing!
