Mocha Typescript and ts-node

[hyndsite]

Hi Thiago,
I see you're a fellow pluralsight author. I came across your article https://templecoding.com/blog/2016/05/05/unit-testing-with-typescript-and-mocha/ and had a question that I am up against that you might have resolved.

I am working with Typescript and using Mocha with ts-node compiler. However, because ts-node maps everything to node I am having a problem anytime test code comes across any types defined in Typescript libraries that does NOT have a node equivalent (e.g. FormData -lib.es6.d.ts, File -lib.dom.d.ts).

I have tried a number of options, including even ///reference path="....lib.dom.d.ts"....

It still throws javascript referenceError for those types (e.g. FormData, File...).

Any suggestions?
