c# - 使用 Rhino 模拟模拟 ASPNET MVC DependencyResolver

Question

在为其中一个业务逻辑(方法)编写单元测试时，无法模拟 ASP NET MVC DependencyResolver，因为它会为此获取 null。下面是这行代码

DependencyResolver.Current.GetService(typeof(ITestDetails)) as ITestDetails;

不知何故想 mock 这一行。

Answer 1

模拟解析器及其预期行为

//create the new resolver that will be used to replace the current one
IDependencyResolver resolver = MockRepository.GenerateMock<IDependencyResolver>();
//mock expected behavior
var testdetails = MockRepository.GenerateMock<ITestDetails>();
resolver.Stub(_ => _.GetService(typeof(ITestDetails))).Returns(testDetails);

并将当前设置为模拟。

//assign the mocked resolver.
DependencyResolver.SetResolver(resolver);

现在当

DependencyResolver.Current.GetService(typeof(ITestDetails))

被调用，它将提供模拟的解析器并在单元测试时按预期运行
