Working on MEDinar, we are doing unit test for test our app. One of the scenario is when users upload their slides. We need to check if everything works. But the problem is I could not find a working example in Java how to test file upload. So after digging and reading few examples how to do it in Scala

I developed a working solution for Java. We have a controller action

import play.mvc.Http; ... public Result importSlides(Long id) { Http.MultipartFormData body = request().body().asMultipartFormData(); Http.MultipartFormData.FilePart file = body.getFile("file"); // handle file if(file == null) { return badRequest("File is missing"); } return ok(); } |
and code to test it
