mongodb - Play-ReactiveMongo plugin: play2 testing a controller with a reactiveMongoApi -

in following, using play2 reactivemongo plugin in version 0.11.0.play24 (https://github.com/reactivemongo/play-reactivemongo) play 2.4.

as mentioned in documentation located @ http://reactivemongo.org/releases/0.11/documentation/tutorial/play2.html, play2 controller mongo instantiated follows:

class mycontroller @inject() (val reactivemongoapi: reactivemongoapi) extends controller mongocontroller reactivemongocomponents { } 

therefore, since controller class , not object, not possible use singleton in test cases.

however, not know how inject reactivemongoapi in order instantiate mycontroller() right parameters in test case (scalacheck or other...)

do have idea/example on how test such controller scalacheck or specs2?

thank in advance!

you can produce mock reactivemongoapi (depending mock framework use):

val reactivemongoapi = mock[reactivemongoapi] 

and can this:

new mycontroller(reactivemongoapi) 

that's simplest approach. use actual reactivemongoapi object:

val app = new guiceapplicationbuilder()   .in(mode.test)   .configure("play.modules.enabled" -> "play.modules.reactivemongo.reactivemongomodule")   .build  val reactivemongoapi = app.injector.instanceof[reactivemongoapi] 

if gets more complicated, example, partially mocked nested dependency tree (this more integration testing unit testing), may want partially mock guice framework explained here.
