Hi,

I would like to test the validation of submitted DTO. This is the bare bone of a controller create action:

[AcceptVerbs(HttpVerbs.Post)]
        public RedirectToRouteResult Create(SomeDTO SomeDTO)
        {
            SomeObject SomeObject = null;

            try
            {
SomeObject = this.RepositoryService.getSomeObjectRepository().Create(SomeDTO, this.RepositoryService);
            }
            catch (BrokenRulesException ex)
            {
                ex.AddModelStateErrors(ModelState, "Model");
            }
            catch (Exception e)
            {
                ModelState.AddModelError("Exception", e.Message);
            }

            TempData["ViewData"] = ViewData;
            TempData["SomeDTO "] = SomeDTO;

            return ModelState.IsValid ? RedirectToAction("SomeObjectDetail", new { Id = SomeObject.Id }) : RedirectToAction("Form");
        }

The mechanics , although not relevant, is as follows: I have a strongly typed view = form which submits a dto to this action which either returns the form or the details page of the created object.

I would like to unit test whether the Model contains certain key/errorMessage combinations given some invalid dto. Did someone do similar stuff? Any pointers would be very much appreciated.

Thanks.

Best wishes,

Christian
