nyc is not working in combination with esm and ts-node

[stevefan1999-personal]

Expected Behavior

Subprocess should load the typescript test file without problem

Observed Behavior

Test failed miserably, so that no coverage rates are computed:

PS <REDACTED> > yarn test:with-coverage
yarn run v1.9.4
$ nyc yarn test:start && nyc report
$ node -r esm -r ./.register.js ./alsatian.ts

Sooo it seems like the issue has been dormant for quite some time, but I do want to point out that upgrading esm and all the related dependencies to the latest version, it magically worked! I even had a chance to run the source with Istanbul, but sadly it's not perfect:

I'm using inline source map (original source incl.) so I think that's why the filename got somewhat verbose. Can someone dealing with similiar situations tell us how to workaround that?

@stevefan1999-personal sorry for the late reply, but I just tried out your repo and it seems to be working fine. Let me know if not and we can reopen this issue or look in some of the others to find similar problems.
