"commandKind": "global",

Please provide more information. (For example, instead of
<Command fails, maybe you can share an error message?)The best way to get issues investigated quickly is to provide a GitHub branch with instructions for reproducing an error.

Tom Sherman (@tom-sherman) Were you able to prepare a branch that repros this issue? If not, we should close this.

I suspect that is failing due to calling "rush jest", as the name given is "test", running "rush test" / "rush test:watch" should be fine, i was quickly trying and is working. At that point you should have a root jest.config or it will not run.
I think it should be better to just build upon heft lib to implement that, calling the start.js from node_modules heft lib in the scope, so you have all the transformations done by heft to execute tests where you need
