copied!<p>I managed to get this working with Play 2.1 based on various mailing list suggestions. Here's how I do it:</p> <pre><code>import scala.language.implicitConversions import java.io.{ ByteArrayOutputStream, File } import org.apache.http.entity.mime.MultipartEntity import org.apache.http.entity.mime.content.{ ContentBody, FileBody } import org.specs2.mutable.Specification import play.api.http.Writeable import play.api.test.{ FakeApplication, FakeRequest } import play.api.test.Helpers._ trait FakeMultipartUpload { case class WrappedFakeRequest[A](fr: FakeRequest[A]) { def withMultipart(parts: (String, ContentBody)*) = { // create a multipart form val entity = new MultipartEntity() parts.foreach { part => entity.addPart(part._1, part._2) } // serialize the form val outputStream = new ByteArrayOutputStream entity.writeTo(outputStream) val bytes = outputStream.toByteArray // inject the form into our request val headerContentType = entity.getContentType.getValue fr.withBody(bytes).withHeaders(CONTENT_TYPE -> headerContentType) } def withFileUpload(fileParam: String, file: File, contentType: String) = { withMultipart(fileParam -> new FileBody(file, contentType)) } } implicit def toWrappedFakeRequest[A](fr: FakeRequest[A]) = WrappedFakeRequest(fr) // override Play's equivalent Writeable so that the content-type header from the FakeRequest is used instead of application/octet-stream implicit val wBytes: Writeable[Array[Byte]] = Writeable(identity, None) } class MyTest extends Specification with FakeMultipartUpload { "uploading" should { "be easier than this" in { running(FakeApplication()) { val uploadFile = new File("/tmp/file.txt") val req = FakeRequest(POST, "/upload/path"). withFileUpload("image", uploadFile, "image/gif") val response = route(req).get status(response) must equalTo(OK) } } } } </code></pre>
