如何在MVC中的动作的单元测试中模拟类

Question

I'm implementing Unit Test on existing software. These software is in ASP.NET MVC, and I want test the return of a Action, of a Controller.

But in this Action a I have the code:

 public ActionResult EditProfile(
        string accountId = null,
        string partnership = null,
        AccountType? subscriptionType = null,
        bool forcePartnerUpdate = false)
    {
        var model = new EditProfileModel();
        var account = _authUser.Account;  
        var catalogClient = new CatalogService.CatalogClient(Request.Cookies, Globals.CatalogURL);

The problem is because the last line : "new CatalogService.CatalogService()"

I'm using this class in other part of Action:

model.ListBrands = new List<Brands>();
model.ListAvailableBrands = new List<Brands>();
model.ListSubscribedBrands = new List<Brands>();
var brands = catalogClient.GetBrandsWithManufacturer();

So, How I can mock this for tests?

I have thought in abstract for a interface and send how a parameter in action, but I don't have the Request in my NInjectModule to IoC and in other codes this class has other parameters, so I think I can't do IoC.

How I can mock this with moq?

Thank you for help.

Answer 1

I've thought and tested a lot and now I got to do the mock for my tests.

First, I've created a "Factory" to my class:

public interface ICatalogClientFactory
{
    ICatalogClient Create(HttpCookieCollection cookies, string catalogUrl);
}

public class CatalogClientFactory : ICatalogClientFactory
{
    public ICatalogClient Create(HttpCookieCollection cookies, string catalogUrl)
    {
        return new CatalogClient(cookies, catalogUrl);
    }
}

Than, this Interface I've registered in the NinjectModule and set this in the constructor of Controller. So, I'm calling in my actions with this code:

  ICatalogClientFactory _catalogClientFactory = catalogClientFactory;
  var clientCatalog = _catalogClientFactory.Create(Request.Cookies, Globals.CatalogURL);

Now, I can mock "ICatalogClientFactory" and "ICatalogClient" to use in unit tests.
