support promises resolve/reject

See original GitHub issue

I got an email asking for promise support. I didn’t think hard about it because I don’t have an immediate need.

What if we had this API?

td.config(promiseProvider: someFuncThatCreatesPromises)

td.when(...).thenResolve(someValue)
td.when(...).thenReject(someOtherValue)

And then maybe on the verification side?

td.verify.resolved(value)
td.verify.rejected(someOtherValue)

I don’t use promises much and I generally don’t TDD with them in mind (since I try to keep async stuff to the periphery of my app where I’m integrating with stuff). Any thoughts on how to go about this or what an example test would look like?

I’ve started working on this issue. See the progress in my fork. Currently, only native Promise is supported.

Thanks @mgryszko – I don’t think I can merge unless we make the Promise constructor configurable. Sadly we live in the era of transpilers & polyfills and I don’t know anyone in practice who uses the native Promise object in production
