Describe is not defined exception on Typescript, Mocha and VSCode

Answering my own question here.

I have figured out the issue after installing Mocha 6.1.1.

On the launch.json, change the args array from "tdd" to "bdd" so that:
"-u", "bdd"

Version 5.x worked with the "tdd" option so the next major version caused this hiccup of a badly written configuration.
