Test MultipartFormData in Play 2.0 FakeRequest

Question

I\'m trying to create a function test for a Play 2 controller which takes multipart form data as input. There is no method currently in FakeRequest to support multipart form

Answer 1

Here is a solution with callAction() in Java to create the multipart/form-data content for a request. It works at least in Play 2.2.3. My content-type was application/zip. You might want to change this.

@Test
public void callImport() throws Exception {
    File file = new File("test/yourfile.zip");
    FilePart part = new MultipartFormData.FilePart<>(
            "file", "test/yourfile.zip",
            Scala.Option("application/zip"), new TemporaryFile(file));
    List> fileParts = new ArrayList<>();
    fileParts.add(part);
    scala.collection.immutable.List> files = scala.collection.JavaConversions
            .asScalaBuffer(fileParts).toList();
    MultipartFormData formData = new MultipartFormData(
            null, files, null, null);
    AnyContent anyContent = new AnyContentAsMultipartFormData(formData);

    Result result = callAction(
            controllers.routes.ref.ImportExport.import(),
            fakeRequest().withAnyContent(anyContent,
                    "multipart/form-data", "POST"));

    // Your Tests
    assertThat(status(result)).isEqualTo(OK);
}
