How to test methods that return Future?

Question

I\'d like to test a method that returns a Future. My attempts were as follows:

import  org.specs2.mutable.Specification
import scala.concurrent.Exec         


        

Answer 1

Took me awhile to find this so thought I'd share. I should've read the release notes. In specs2 v3.5, it is required to use implicit ExecutionEnv to use await for future. This can also be used for future transformation (i.e. map) see http://notes.implicit.ly/post/116619383574/specs2-3-5.

excerpt from there for quick reference:

import org.specs2.concurrent.ExecutionEnv

class MySpec extends mutable.Specification {
  "test of a Scala Future" >> { implicit ee: ExecutionEnv =>
    Future(1) must be_>(0).await
  }
}
