错误：意外请求：DELETE / rez / remove / resume / mockFile1

Question

我是角色的新手，我正在为服务编写单元测试。所以我有一个删除请求所以，我面临一些Error: Unexpected request: DELETE /rez/remove/resume/mockFile1 ，

it('should give the message after deleting the file', function() {
           var fileName1 = "mockFile1";
           var documentType = "resume";
           httpBackend.expect('DELETE', 'rez/remove/resume/mockFile1').respond(
               "File is removed"
           );

           uploadService.deleteFile(fileName1, documentType)
                .then(function(response) {
                    expect(response).tobe('File is removed');
                });
       });

所以，这里当我调用请求时，响应是一个"File is removed"的字符串  但在这里我面临着这个错误。任何人都可以告诉我这里的问题吗？提前谢谢。
