问题 In the following code why does mockTest.ToString() return Null? EDIT: Added comment into example code to show how to fix the problem. Public Sub Main() Try Dim test = New TestClass If test.ToString <> "stackoverflow rules" Then Throw New Exception("Real Failed: Actual value: <" + test.ToString + ">") End If Dim mock = New Moq.Mock(Of TestClass)() mock.SetupGet(Function(m As TestClass) m.Name).Returns("mock value") ' As per Mark's accepted answer this is the missing line of ' of code to make

问题 How do I force AutoFixture, that has been configured with AutoConfiguredMoqCustomization, to automatically mock interfaces and its read-only properties? To make things clear, let's assume I have such an interface: public interface A { int Property {get;} } and such class: public class SomeClass { public SomeClass(A dependency) {} } What I want is to have dependency resolved to a mock that will return something in dependency.Property : var fixture = new Fixture().Customize(new

Why is my mock set empty?

阅读更多关于 Why is my mock set empty?

I am just starting to learn about unit testing and mocking. I've spent all day reading different tutorials, trying to find the best one to practice with. I've settled on Testing with a mocking framework (EF6 onwards) as it is using EF6 (modern), as well as what seems to be a very popular mocking framework (Moq). Also, it is quite vanilla and hosted on the MSDN webset. It has to be decent, right? I've set up a project exactly as specified in the example and am running the debugger through the test examples to make sure I understand what is going on. The test I'm working through is as follows:

问题 I'm using Moq in my code. I wrote an expression like: mockInvoice.VerifySet(x => x.InvoiceAttachmentId, Times.Once()); Where InvoiceAttachmentId is a property on my Invoice. It works fine but I get the warning: Moq.MockExtensions.VerifySet(Moq.Mock, System.Linq.Expressions.Expression>, Moq.Times)' is obsolete: 'Replaced by VerifySet(Action, Times)' Can anyone tell me how to rewrite it to satisfy the compiler and get rid of the warning? I'm unsure how to make the replacement to Action. 回答1:
