I am essentially asking the exact same question here. As you can see, there are no solid answers. All I want to do is send a file using HTTPUnit to test a java servlet.

So, I have a Java Servlet with this code (dumbed down):

@WebServlet("/properties/StorePropertyAttachment")
@MultipartConfig
public class StorePropertyAttachment {

    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{
        final Part p = req.getPart("propertyImage");
         ....
    }
}

Here is the important part of my test case:

    ServletRunner servletRunner = new ServletRunner();
    servletRunner.registerServlet("StorePropertyAttachment", StorePropertyAttachment.class.getName());

    WebRequest webRequest = new PostMethodWebRequest(WEB_REQUEST_BASE_URL + STORE_PROPERTIES_ENDPOINT);
    UploadFileSpec spec = new UploadFileSpec(new File("C:/test.jpg"), "multipart/form-data");
    webRequest.setParameter("propertyImage", new UploadFileSpec[] {spec});
    ^^^^^  line 68  ^^^^^

    ServletUnitClient servletClient = servletRunner.newClient();
    WebResponse webResponse = servletClient.getResponse(webRequest);

When I run this, I get this error: 

com.meterware.httpunit.IllegalNonFileParameterException: Parameter 'propertyImage' is not a file parameter and may not be set to a file value.
    at com.meterware.httpunit.WebRequest.setParameter(WebRequest.java:232)
    at com.amsgeo.mspworkmanager.services.properties.PropertyAttachmentTest.test(PropertyAttachmentTest.java:68)
    ....

Just for kick, if I change line 68 to this (a normal parameter): 

webRequest.setParameter("propertyImage", "some string");

I get this error (from within my servlet my the way):

java.lang.AbstractMethodError: com.meterware.servletunit.ServletUnitHttpRequest.getPart(Ljava/lang/String;)Ljavax/servlet/http/Part;

at com.amsgeo.mspworkmanager.services.properties.PropertyAttachmentTest.testNoParam(PropertyAttachmentTest.java:70)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
....

I don't know why it wont let me add the file.

Any suggestions??

EDIT:

I am trying to submit this using a form from a local html file. I am loading the form in successfully but am getting a 404. Here is my form declaration.

<form method="POST" action="http://localhost/StorePropertyAttachment" enctype="multipart/form-data" name="propertyImageTest">
    <input type="file" name="propertyImage" />
    <input type="submit" />
</form>

Updated test code:

    ServletRunner servletRunner = new ServletRunner();
    servletRunner.registerServlet("StorePropertyAttachment", StorePropertyAttachment.class.getName());

    WebConversation conversation = new WebConversation();
    WebRequest  request = new GetMethodWebRequest("file:/C:/test.html");
    WebResponse response = conversation.getResponse(request);
    WebForm form = response.getFormWithName("propertyImageTest");   
    UploadFileSpec uploadFileSpec = new UploadFileSpec(new File("C:/test.jpg"), "image/jpeg"); 
    form.setParameter("propertyImage", new UploadFileSpec[] {uploadFileSpec});

    WebResponse webResponse = form.submit();

第三个 UploadFileSpec 构造函数参数不应该是内容类型而不是消息类型吗？在您的情况下将是“图像/JPEG”。

你需要一个网络表单

WebConversation conversation = new WebConversation();
WebRequest  request = new GetMethodWebRequest("http://your-site-to-test.com/path-to-your-upload-form");
WebResponse response = conversation.getResponse(request);
WebForm form = response.getFormWithName("stockImageUpload");   
UploadFileSpec uploadFileSpec = new UploadFileSpec("test.jpg",new File("C:/test.jpg"), "image/jpeg"); 
form.setParameter("propertyImage", new UploadFileSpec[] {uploadFileSpec});

您确实需要按照第一篇文章的唯一答案中的建议深入研究测试框架文档。

编辑：getPart()ServletRunner 中的 servlet 实现不支持该方法，这就是为什么您无法在另一边获得任何部分并获得 AbtractMethodError。
