scala test play parse.mulipartFormData

Attempting to test a play function that parses a multipartFormData

def requestBulkSiteSbcActionConfirm = Action.async(parse.multipartFormData) { request => ....

The test i've created is 

      val temporartyFile = TemporaryFile("test")
  val filePart = FilePart("key: String", "test.csv", None, temporartyFile)
  val multipartFormData: MultipartFormData[TemporaryFile] = MultipartFormData(Map(),Seq(filePart), Seq())
  val request: Request[AnyContentAsMultipartFormData] = FakeRequest().withHeaders(("Content-Type"->"multipart/form-data")).withMultipartFormDataBody(multipartFormData)
  val pw = new PrintWriter(filePart.ref.file)
  pw.write(s"$TestSiteId_1, ${AdLeft.id}, on\n")
  pw.write(s"$TestSiteId_2, ${AdRight.id}, off\n")
  pw.close()
  val acc: Accumulator[ByteString, Result] = controller.requestBulkSiteSbcActionConfirm().apply(request)

which exceptions

Solution

  • Some internal parts of Play still uses a global state for execution, it seems you just hit one: https://github.com/playframework/playframework/blob/2.5.x/framework/src/play/src/main/scala/play/api/mvc/ContentTypes.scala#L657

    This should change with play 2.6 but meanwhile you should start an application in your test to make it work
