Simple response mocking for dispatch using scalamock

RequestSpec.scala

// Example for lukaseichler.de/how-to-test-dispatch-request/

import dispatch.{HttpExecutor, _}
import dispatch.Defaults._

val httpMock = mock[HttpExecutor]
(httpMock.apply(_: (Request, AsyncHandler[String]))(_: ExecutionContext))
.expects(*, *)
.returning(Future[String] {
  "Hello World"
})

class Foo(http: HttpExecutor = Http) // Allow to override default HttpExecutor
