The issue I have is that mocha-typescript keeps throwing an error that describe is not defined.

npm ERR! Test failed. See above for more details.
As you can see I've tried multiple things such as settings typeRoots and types in tsconfig.json, import mocha and two different type definiton files. None of them worked and I'm tangled up in all the possible combinations.
I've been trying to get typescript-mocha running for a while now and sometimes it works, sometimes it doesn't. A clear explanation I don't have, but I'd certainly like one.
