It seem like the author of the code really hasn't emphasized testability, which has forced users to come up with their own novel solutions. This one by user jeantil could be helpful:
class FakeAuthenticatorStore(app:Application) extends AuthenticatorStore(app) {
var authenticator:Option[Authenticator] = None
def save(authenticator: Authenticator): Either[Error, Unit] = {
this.authenticator=Some(authenticator)
Right()
}
def find(id: String): Either[Error, Option[Authenticator]] = {
Some(authenticator.filter(_.id == id)).toRight(new Error("no such authenticator"))
}
def delete(id: String): Either[Error, Unit] = {
this.authenticator=None
Right()
}
}
abstract class WithLoggedUser(val user:User,override val app: FakeApplication = FakeApplication()) extends WithApplication(app) with Mockito{
lazy val mockUserService=mock[UserService]
val identity=IdentityUser(Defaults.googleId, user)
import helpers._
import TestUsers._
def cookie=Authenticator.create(identity) match {
case Right(authenticator) => authenticator.toCookie
}
override def around[T: AsResult](t: =>T): execute.Result = super.around {
mockUserService.find(Defaults.googleId) returns Some(identity)
UserService.setService(mockUserService)
t
}
}
val excludedPlugins=List(
,"service.login.MongoUserService"
,"securesocial.core.DefaultAuthenticatorStore"
)
val includedPlugins = List(
"helpers.FakeAuthenticatorStore"
)
def minimalApp = FakeApplication(withGlobal =minimalGlobal, withoutPlugins=excludedPlugins,additionalPlugins = includedPlugins)
which then allows testing like this
"create a new user password " in new WithLoggedUser(socialUser,minimalApp) {
val controller = new TestController
val req: Request[AnyContent] = FakeRequest().
withHeaders((HeaderNames.CONTENT_TYPE, "application/x-www-form-urlencoded")).
withCookies(cookie) // Fake cookie from the WithloggedUser trait
val requestBody = Enumerator("password=foobarkix".getBytes) andThen Enumerator.eof
val result = requestBody |>>> controller.create.apply(req)
val actual: Int= status(result)
actual must be equalTo 201
}
