file type need to be
org.springframework.web.multipart.MultipartFile. This is the super interface above
CommonsMultiPartFile and
MockMultipartFile. If you have done this, then you can create a mock of the multipart file itself with an mock object that is provided by spring, just like below
:
MockMultipartFile mockMultipartFile = new MockMultipartFile(String name, String originalFilename, String contentType, byte[] content);
