Jasmine spyOn function argument object, as Variables are not defined

Question

I am wiring jasmine test cases for one of the application. I have just started learning jasmine. Below is my script code

var aclChecker = function(app,config) {

    validateResourceAccess = function (req, res, next) {
            req.callanotherMethod();
            res.send(401,'this is aerror message');
   }

}

Now i want to spyOn res and req object to know if send method has been called. As req and res are not global variables i am having this doubt on how to create a spy on in junit spec

Please help!!!!!!!!

You can simply mock req and res like this.

  describe("acl checker", function() {
    it("should validate resource access", function() {
      var mockReq = {
          callAnotherMethod: function() {}
      };
      var mockRes = {
        send: function() {}
      };
      var mockNext = {};
      spyOn(mockReq, "callAnotherMethod");
      spyOn(mockRes, "send");

      aclChecker.validateResourceAccess(mockReq, mockRes, mockNext);
      expect(req.callAnotherMethod).toHaveBeenCalled();
      expect(res.send).toHaveBeenCalledWith(401, 'this is aerror message');
    });
  });
