    }

So just looking through the code you can probably tell what it does. Each controller action refers to a different desired result, and I'm passing in (for the most part), a Guid? id Guid? id , and we are using that id to call into the private helper methods, get the model , and return a specific view based on that model .

I really don't even know where to begin to unit test this class. Can I get some help here? Thanks!

Answer 1

Well, to start with, you should test to make sure that a specific Guid passed in results in a ViewResult with the right View location set. AKA

ActionResult action = _myControllerToTest.Notes(null, null);
Assert.IsNotNull(action);

ViewResult viewResult = action as ViewResult;
Assert.IsNotNull(viewResult);

// Check viewResult for correct view path and model data

Start there, and make sure to inject the depdencies (particularly for that isModelValid() method, since it calls out to CachedTransactionManager)
