In Js tests, mocha, chai and sinon are commonly exposed as global variables to save some import, usually via karma plugins.
Installing mocha typings goes well, mocha describe, it... are correctly exposed as global variables with correct types.
However, trying to also expose chai and sinon typings as global vars (typings i --global --save-dev sinon) yields me a :
typings ERR! message Attempted to compile "sinon" as a global module, but it looks like an external module.`
I tried to write a typings file myself, but I don't have access to those libs typings (import ?)...
Is it possible ? How should I do it ? And will it work with sinon-chai ?
