scala - Guice , unable to create injector -


im trying create in injector testing api.

the test binding follows   class apitestmodule extends abstractmodule {     def configure(): unit = {       bind(classof[client]).in(classof[singleton])       bind(classof[apigetcontroller]).in(classof[singleton])       bind(classof[apipostcontroller]).in(classof[singleton])       bind(classof[indexservice]).in(classof[singleton])       bind(classof[panelservice]).in(classof[singleton])       bind(classof[entitiesservice]).in(classof[singleton])       bind(classof[authenticatedpublicapiaction]).in(classof[singleton])       bind(classof[ratelimitedapiaction]).in(classof[singleton])       bind(classof[apikeyvalidatorupdaterthread]).in(classof[singleton])       bind(classof[apikeyvalidatorservice]).in(classof[singleton])       bind(classof[articlefrontservice]).in(classof[singleton])      }

i've created te injector in code 

 val testmodule = new abstractmodule() {     def configure() = {       new apitestmodule().configure(binder())     }   }   val injector = new guiceapplicationbuilder()     .overrides(testmodule).injector()    val apigetcontroller = injector.instanceof(classof[apigetcontroller])

and i'm getting following error

exception or error caused run abort: unable create injector, see following errors:

)

i think issue in my bindings module cant figure out issue is. appreciated.

mockito useful testing. think can try below injection testing guice 

class testmodule extends abstractmodule mockitosugar {    val mockclient: client = mock[client]    override def configure(): unit = {     bind(classof[client]).toinstance(mockclient)   }  }

it easy mocking , stubbing. if want mock or stub in test can use this

doreturn("dummyresult").when(testmodule.mockclient).somemethod()
