Play 2.5 Unit testing controller failed with ScalaTestPlus

[Tianhao Li]

val request = fakeRequest("POST", "/user").withJsonBody(Json.parse(
      s"""{"first_name": "Alice",
        |  "last_name": "Doe",
        |  "credentials": {
        |    "username": "alice",
        |    "password": "secret"
        |  }
        |}""".stripMargin))
    val apiResult = call(testController.createUser, request)

In my controller unit test, I got something like above before.

However when I upgrade to Play 2.5, I got some error:

could not find implicit value for parameter mat: akka.stream.Materializer

However, when I did like docs, 

https://www.playframework.com/documentation/2.5.x/ScalaTestingWithScalaTest#Unit-Testing-EssentialAction

I still have some error like no such method error about FakeApplication for ScalaTestPlus.

Anyone has idea about this?

WHY I got so many broken changes after upgrading to Play 2.5??????

It looks like you are importing the wrong WithApplication:

You should import:

import play.api.test.WithApplication

and no:

import play.test.WithApplication
