scala 测试 parse.mulipartFormData

Question

正在尝试测试解析 multipartFormData 的播放函数

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

我创建的测试是

      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)

哪些例外

Play的一些内部部分仍然使用全局状态来执行，看来你只是打了一个：https://github.com/playframework/playframework/blob/2.5.x/framework/src/play/src/main/scala/play/api/mvc/ContentTypes.scala#L657

这应该会随着 play 2.6 而改变，但同时您应该在测试中启动一个应用程序以使其工作

scala 测试 parse.mulipartFormData

scala test play parse.mulipartFormData
