Connection reset on testing file uploads

[Laksh Gupta]

Hi 

I am using REST- assured to simulate the upload functionality for testing the application I have written using Spring in Java. The file I am using just contains "hi" and hence is very small. But still I am getting 'connection reset error'. Here is what I have in the code:

1. rest-assured test case:

given()
        .multiPart(new File("test/testFile.txt"))
        .when()
        .post("/upload")
        .then()
        .statusCode(200)

2. Error:

3. Controller

@RequestMapping(method = RequestMethod.POST)
public Boolean upload(@RequestParam("files") MultipartFile[] files) throws IOException, InterruptedException {
    if(files != null && files.length > 0)
    {
        for (MultipartFile file : files) {
            System.out.println(file.getOriginalFilename());
        }
    }

    return true;
}

I am not sure what I am missing here. Any help is appreciated. Thanks.

Perhaps you need to supply "files" as control name?

Thanks for the reply Johan. I got the same error on using 'files' as control name.

[Johan Haleby]

Are you using vanilla REST Assured or the Spring MockMvc module?

[Laksh Gupta]

Vanilla REST Assured. I tried my test with Apache HTTP client is getting the same error. I guess the problem I have might not be related to REST Assured, but rather how spring is configured. I am able to test the functionality by creating an HTML page, which works fine. I'll try in a Spring forum somewhere. Thanks for your help Johan.

Ok, please tell us what was wrong if you get it working.
