The code now is looking like this:

object UserPresenterTest : Spek({

    given("the user presenter") {

        val request = mock<Request>()
        val response = mock<Response>()

            afterGroup { userFactory.clear() }

                it("should have a positive match for valid user from json") {
                    val user = userFactory.build()
                    doReturn(user.toJson()).whenever(request).body()

                    <http://userPresenter.post|userPresenter.post>(request, response)
                    userPresenter.user.isValid().shouldBeTrue()
                }
            }
        }
    }

})
