Easy testing jspm project with jest or other framework?

So I wanted to use Jest with my jspm project to write some unit tests, but it turned out it's not so easy... Well, it even turned out it's not so easy with any other testing framework.

How do I write tests for my jspm app? Which framework should I choose? Everything that I look up is quite complicated. I haven't found an easy solution. Every framework seems to require a bunch of workarounds to get things working in jspm setup. I feel kind of lost at the moment

If not Jest, then what would be the least painful way of testing an app in jspm setup?
