Spring MockMVC inject mockHttpServletRequest when not in method signature

Question

Given I have inherited some Spring MVC controller code with signature

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public ModelAndView upload(HttpServletRequest request, HttpServletResponse response) {

  String remoteAddress = request.getRemotedAddr();
  auditService.logAddress(remoteAddress);

  // do work...

  return mav;
}

and I have a Spring MockMvc test that performs the test

public void someTest() {
    mockMvc().perform(fileUpload("/upload").file(FileFactory.stringContent("myFile")));

    // do work...
    verify(auditService.logAddress("123456"));
}

I need to set the remote address to "12345" on the HttpServletRequest object that is passed into my upload controller method, so I can verify the call to mock auditService in the test.

I can create a MockHttpServletRequest object and call the setRemoteAddr() method, but how to pass this mock request object to the mockMvc() method call?

Answer 1

You can add a RequestPostProcessor. Which you can then pass in to the mockmvc stuff by using the with() method.

mockMvc().perform(
  fileUpload("/upload")
  .file(FileFactory.stringContent("myFile"))
  .with(new RequestPostProcessor() { 
    public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {
       request.setRemoteAddr("12345"); 
       return request;
    }}));

Something like that should work.
