Testing Endpoints

As asked on the Gitter channel, it would be nice to provide a meaning for testing Finch endpoints (routers).

The idea I’m suggesting relies on types we expose from endpoints (that’s a very good excuse to have them) and allows the users to treat endpoints as a regular functions so they could be easily tested.

Here is the example.

case class User(name: String)

val getUser: Endpoint[User] = get("users" / long) { id: Long =>
  User(id.toString)
}

// test
getUser.lift(100) shouldBe User("100")

The lift (or whatever) method lifts the endpoint to a function (A, B, ..., Z) => Out, where (A, B, ..., Z) are values extracted fromt the request by endpoint and Out is a returned value.

Not sure if it’s even possible, but I’d like to move Finch (make required chnages) towards the direction it will be possible.

Yup, I’ll start working on this.
