Question:
var mocks = new MockRepository(); var access = new Access(); access.ShowRepository = _mocks.Stub<IShowRepository>(); access.ShowRepository.Stub(x => x.GetShows()).Return(new List<Show>()); var kernel =_mocks.Stub<IKernel>(); kernel.Stub(x => x.Get<Access>()).Return(access); This throws an ArgumentNullException:
Message: Value cannot be null.
Parameter name: source
Stack Trace: at System.Linq.Enumerable.Cast[TResult](IEnumerable source) at Ninject.ResolutionExtensions.Get[T](IResolutionRoot root, IParameter[] parameters) at MediaMover.Unit.Tests.ViewModelTests.OptionsViewModelTests.b__1(IKernel x) in C:\Users\Dave\Documents\Visual Studio 2010\Projects\Gigatube\MediaMover.Unit.Tests\ViewModelTests\OptionsViewModelTests.cs:line 33 at Rhino.Mocks.RhinoMocksExtensions.Expect[T,R](T mock, Function2 action) at Rhino.Mocks.RhinoMocksExtensions.Stub[T,R](T mock, Function2 action) at MediaMover.Unit.Tests.ViewModelTests.OptionsViewModelTests.Initialize() in C:\Users\Dave\Documents\Visual Studio 2010\Projects\Gigatube\MediaMover.Unit.Tests\ViewModelTests\OptionsViewModelTests.cs:line 33
Solution:1
I was able to solve this, I had to create a test module and a test provider and pass my mocks through those.
class DbAccessProvider : Provider<Access> { public Access DbAccess { get; set; } protected override Access CreateInstance(IContext context) { return DbAccess; } } class TestModule : NinjectModule { public DbAccessProvider DbAccessProvider { get; set; } public override void Load() { Bind<Access>().ToProvider(DbAccessProvider); } } Here is my SetUp from my test:
access = new Access(); access.SettingsRepository = MockRepository.GenerateStub<ISettingsRepository>(); access.ShowRepository = MockRepository.GenerateStub<IShowRepository>(); access.SettingsRepository.Stub(x => x.GetById(1)).Return(_settings); DbAccessProvider dbAccessProvider = new DbAccessProvider(); dbAccessProvider.DbAccess = access; TestModule testModule = new TestModule(); testModule.DbAccessProvider = dbAccessProvider; var kernel = new StandardKernel(testModule); target = new OptionsViewModel(kernel); Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
