promise-mock

Synchronous promise mock for tests. Implemented using Typescript so types are provided with the library. Also, the mock class implements Promise interface so you can use it wherever a real Promise is required.

Forked and inspired by @slavik57's promise-sync. I felt that his original implementation is a bit outdated and, more importanty, it does not implement Promise interface so it is painful to use in places where a real promise is required. (See slavik57/promise-sync#15 for my original issue)
