This is really frustrating, if not surprising. Jest generally just works out of the box for me with Typescript (and ts-jest), including coverage, whereas the Mocha ecosystem tends to involve wrangling multiple packages with varying levels of Typescript compatibility. Jest has generally been slower to run, though, and I've noticed various problems over the years that aren't getting solved due to the lack of maintenance.

I think this is okay with javascript.
I’ve been considering switching from karma to jest for our angular project, this certainly brings a new angle to that decision.
Frustrating. I guess I get crappy karma “supported” by google, or the much better jest that’s maintained by one person with almost no backing.

I've used this for years and never even knew it came out of Facebook
