autofixture

问题 I started to use moq but from my understanding I always have to mock up all the methods that could be called even if I really do not care about them. Sometimes it takes so long to mockup stuff you forget what you want to do. So I been looking at auto mocking but I am not sure what one I should use. AutoFixture as an auto-mocking container Automocking I don't get how to use the first one at all. I sort of get the second one but never really tried it. I am not sure if one is better than the

问题 Is it possbile to configure AutoFixture so that it adheres the entity constraints [from the EDMX file]? E.g. Consider a snippet from the CSDL section of my EDMX file: <EntityType Name="RndtAd"> ... <Property Name="AD" Type="Decimal" Precision="12" Scale="0" Nullable="false" /> <Property Name="USERNAME" Type="String" MaxLength="255" FixedLength="false" Unicode="true" /> <Property Name="VERSION" Type="Decimal" Precision="12" Scale="4" Nullable="false" /> <Property Name="EFFECTIVE_FROM" Type=

问题 Currently, I'm using custom made fake objects that behind the scenes use NSubstitute which creates the actual objects but it's becoming very hard to maintain as the project grows, so I'm trying to find alternatives and I'm hoping that AutoFixture is the right tool for the job. I read the documentation and I'm struggling because there's very little to no documentation and I read most of the blog posts by Mark Seemann including the CheatSheet. One of the things that I'm having hard time to

问题 I have a need for customizing creation of a collection, with quite complicated relationships between the objects within it, and I can't figure out how to do it correctly. For the sake of this issue, let's assume I'm working on a todo app. It has Item s and SubItem s, and the items have a week number indicating when they should be done: public class Item { public string Name { get; set; } public int Week { get; set; } public ICollection<SubItem> SubItems { get; set; } } public class SubItem {

问题 I am trying to use conventions in my unit tests which make use of AutoFixture. I have a Password value object as shown: public class Password : SemanticType<string> { private int _daysPasswordValid; public Password(string password) : base(IsValid, password) { Guard.NotNullOrEmpty(() => password, password); Guard.IsValid(() => password, password, IsValid, "Invalid Password"); DateCreated = DateTime.Now; } static bool IsValid(string candidate) { //password cannot contain be whitespace if

问题 how do I create a collection of classes which always have a certain predefined value set in AutoFixture? Fixture.Register<IList<Child>>(() => Fixture.CreateMany<Child>().ToList()); Say the child class has the following: public class Child { public int ParentId { get; set; } public int ChildId { get; set; } public string ChildName { get; set; } public int ChildValue { get; set; } } How do I ensure the anonymous classes always have the same parent Id whilst all other properties can be random? I

问题 I need to enable AutoFixture to create instances of types with circular references (from an API provided by a third party). To do this I can remove the default ThrowingRecursionBehavior as shown below: public class RecursiveObjectCustomization : ICustomization { public void Customize(IFixture fixture) { fixture.Behaviors.OfType<ThrowingRecursionBehavior>() .ToList() .ForEach(b => fixture.Behaviors.Remove(b)); fixture.Behaviors.Add(new OmitOnRecursionBehavior()); } } However, I understand that

问题 I am trying to exclude certain enumeration values such as Unknown and Uninitialized from the set of values for any enumeration type . I can see that Enums are generated in a round robin fashion using the EnumGenerator from the set of all possible Enum values for a given Enum type. Based on that code, my first thought is to build an ISpecimenBuilder that checks for Type.IsEnum and does a context.Resolve(request) until Resolve returns a value that is not on the excluded list. The problem is

问题 I am having trouble expressing the following code in a declarative fashion: [Theory] [InlineData(@"-o=C:\Temp\someFile -p=1")] [InlineData(@"-p=1 -o=C:\Temp\someFile")] public void ParseMissingParameterShouldReturnCorrectResult( string argsString ) { ..... var fixture = new Fixture(); fixture.Register<IFoo>(fixture.Create<Foo>); fixture.Register<IBar>(fixture.Create<Bar>); var sut = fixture.Create<SomeClass>(); ..... } In my production code, I've got something like: new SomeClass(new Foo(new

问题 I am wondering in AutoFixure, is there a way to randomly choose from the predefined list? For example, when I use fixture.Create or fixture.CreateMany , it randomly selects an object from the predefined list. I did not find anything similar from documentation and searching Stack Overflow, so I am not sure it is even possible. 回答1: You can use ElementsBuilder<T> : [Fact] public void Example() { var fixture = new Fixture(); fixture.Customizations.Add( new ElementsBuilder<MyObject>( new MyObject
