Sharepoint Framework with custom npm package and testing

Background Info

I'm having trouble testing my solution once I've included a custom npm package (through VSTS). I've setup my tests by following Elio Struyf's https://www.eliostruyf.com/writing-unit-test-for-your-sharepoint-framework-components/ and created a npm package following another https://codeburst.io/https-chidume-nnamdi-com-npm-module-in-typescript-12b3b22f0724 I found on the subject. I then followed VSTS guide for setting up the package for distribution and seemingly everything works.

 

Trouble

Once I added the package and ran gulp test I got the following error from karma/PhantomJS:

Frankly I don't even know where to begin as I've never used Karma or Phantom before. I've tried going through the npm demo again and comparing my package to others and noticed no apparent discrepancy. 

 

All help greatly appreciated, I'll gladly provide sources for anything that might help but I decided not to overcrowd this original post :)

    Turns out it was quite basic, I had my main index.js file according to the npm package's package.json set wrong. That wasn't apparent because TypeScript picked up the original index.ts in the root. PhantomJS / Karma then didn't understand that file and couldn't find the correct index.js file.
