Always TS + mocha/jest. The

promise()

method has to be exposed in every file, which is a bit annoying:

declare module "@pulumi/pulumi" {
  export interface OutputInstance<T> {
    promise(withUnknowns?: boolean): Promise<T>;
  }
}

It'd be great if there were equivalent of

expect().resolves

and

expect().rejects

(and chai-as-promised's

eventually

) for Outputs 🙂
