问题 I'm trying to proxy calls to a fake object to the actual implementation. The reason for this is that I want to be able to use the WasToldTo and WhenToldTo of Machine.Specifications which only works on fakes of an interface type. Therefore I'm doing the following to proxy all calls to my real object. public static TFake Proxy<TFake, TInstance>(TFake fake, TInstance instance) where TInstance : TFake { fake.Configure().AnyCall().Invokes(x => x.Method.Invoke(instance, x.Arguments.ToArray()));

问题 I have the following test: [Fact] public void StartProgram_CallsZoneProgramStart() { var zone = A.Fake<Zone>(); zone.StartProgram(); A.CallTo(() => zone.ZoneProgram.Start(null, A.Dummy<ActionBlock<InterruptInfo>>())).MustHaveHappened(Repeated.Exactly.Once); } It's creating a dummy of type ActionBlock<InterruptInfo> which is being passed into the MustHaveHappened call. zone.StartProgram definitely calles the zone.ZoneProgram.Start method, but this call is not seen by FakeItEasy. It returns the

问题 I have been using Moq for my mocking needs the last years, but after looking at FakeItEasy i wanted to give it a try. I often want to test that a method have been called with the correct parameters, but i found no satisfactory way to do this with FakeItEasy. I have the following code to test: public class WizardStateEngine : IWizardStateEngine { private readonly IWorkflowInvoker _workflowInvoker; private List<CustomBookmark> _history; public WizardStateEngine(IWorkflowInvoker workflowInvoker)

问题 I’m using xUnit, SubSpec and FakeItEasy for my unit tests. I’ve so far created some positive unit tests like the following: "Given a Options presenter" .Context(() => presenter = new OptionsPresenter(view, A<IOptionsModel>.Ignored, service)); "with the Initialize method called to retrieve the option values" .Do(() => presenter.Initialize()); "expect the view not to be null" .Observation(() => Assert.NotNull(view)); "expect the view AutoSave property to be true" .Observation(() => Assert.True

问题 I'm using a controller extension, and I tried to mock it using FakeItEasy (v 1.7.4) like this: A.CallTo(() => controller.RenderView(A<string>.Ignored,A<object>.Ignored,null)).Returns(""); but I get this error: System.NullReferenceException : Object reference not set to an instance of an object. at System.Object.GetType() at FakeItEasy.Creation.ProxyGeneratorSelector.MethodCanBeInterceptedOnInstance(MethodInfo method, Object callTarget, ref String failReason) at FakeItEasy.Configuration

问题 I want to assert that nothing was dispatched , a.k.a. _dispatcher.Dispatch was not called . interface being faked/mocked: interface IDispatcher { void Dispatch<T>(T command, Stuff stuff = null, TimeSpan? timeout = null, int? retries = null) where T : Command; } In the test body: _dispatcher = A.Fake<IDispatcher>(); // do stuff A.CallTo(() => _dispatcher.Dispatch(A<Command>.Ignored, A<Stuff>.Ignored, A<TimeSpan?>.Ignored, A<int?>.Ignored)).MustNotHaveHappened(); This test passes when something

问题 I am using the Captcha class from commonlibrary (http://commonlibrarynet.codeplex.com/). My code works and everything but now I'm trying to write the unit test. My validation rule is: RuleFor(x => x.CaptchaUserInput) .NotEmpty() .Must((x, captchaUserInput) => Captcha.IsCorrect(captchaUserInput, x.CaptchaGeneratedText)) .WithMessage("Invalid captcha code"); In my set up code I tried to do the following: A.CallTo(() => Captcha.IsCorrect()).Returns(true); but I get the following error message:

问题 I have an interface public interface IInterface { void DoSomething(); } Another interface public interface IOtherInterface : IInterface { } An abstract class public abstract class AbstractClass : IInterface { public void DoSomething() { Console.WriteLine("Got here"); } } I'm writing a unit test and fake IOtherInterface. The abstract class already contains helpful methods I'd want to leverage for my unit test. How would I make my A.Fake<IOtherInterface>(); inherit from AbstractClass ? This is

问题 I'm working with the FakeItEasy library to create fakes for my unit tests. I have a ClassUnderTest on which I want to test the method MethodToTest(Data dataObject) . This method is calling a method of an interface which I want to fake: public interface IFoo { void Execute(Action<IDataAccess> action); } public class ClassUnderTest { private IFoo _foo; public ClassUnderTest(IFoo foo) { _foo = foo; } public void MethodToTest(Data dataObject) { _foo.Execute(dataAccess => dataAccess.Update

问题 How can I mock/facke the result from a function that is called in another function? Usually Test2 would be a DataAccess method that I dont like to fetch real data. What I like my unittest to test is the business logic. This Is what I have now but its not working at all. Sum is always asserted as 5! public int Test1() { var value = this.Test2(); //Unittest should substitute with 5 var businesslogic = value + 10; //The business logic return businesslogic; } public int Test2() { return 10; //I
