How can I fix the missing implicit value for parameter ta: TildeArrow in a test spec

Question

I\'m working on a simple test spec using spray and I can\'t get it to compile correctly, don\'t know if I\'m doing anything wrong. My version of scala is 2.9.3 and spray 1.0

To expand a bit on previous answers given, there are some implicits which shouldn't be declared by any other Trait or class that is extends by your Test Class :

• the ActorSystem
• the ExecutionContext
• the DefaultHostInfo (package akka.http.scaladsl.testkit)
• the ActorMaterializer

if any of these is declared elsewhere than in ScalatestRouteTest, you'll have the following error thrown :

could not find implicit value for parameter ...TildeArrow[RequestContext, SomethingHereOther]
