Question

我使用Unity创建CustomerService的实例。这适用于ASP.NET MVC应用程序中的以下代码。

当我创建ASP.NET MVC应用程序时，我创建了ASP.NET MVC测试项目。我想测试一下这些动作（这里：/Home/Index）。问题是我无法设置Unity。我想创建一个真正的动作调用，而不是嘲笑。

您是否了解测试项目中的设置？我试过这个，但是当我调用控制器时，我找不到正确的语法来创建CustomerService的实例作为参数。

[TestMethod]
public void Index()
{
    var container = UnityConfig.GetConfiguredContainer();

    //I don't find the right syntax for resolve
    ICustomerService customerService = container.Resolve??????

    HomeController controller = new HomeController(customerService);
    ViewResult result = controller.Index() as ViewResult;
    Assert.IsNotNull(result);
    container.Dispose();
}

ASP.NET MVC应用程序中使用的工作代码

namespace MyTestMVC
{
    public class HomeController : Controller
    {
        private readonly ICustomerService _customerService;

        public HomeController(ICustomerService customerService)
        {
            _customerService = customerService;
        }

        public ActionResult Index()
        {
            var result = _customerService.MyMethod();
            //.....
            return View();
        }
    }
}

//I set Unity like this : 
namespace MyTestMVC.App_Start
{
    public class UnityConfig
    {
        private static Lazy<IUnityContainer> container = new Lazy<IUnityContainer>(() =>
        {
            var container = new UnityContainer();
            RegisterTypes(container);
            return container;
        });

        public static IUnityContainer GetConfiguredContainer()
        {
            return container.Value;
        }

        public static void RegisterTypes(IUnityContainer container)
        {
            container.RegisterType<ICustomerService, CustomerService>();
        }
    }
}

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(MyTestMVC.App_Start.UnityWebActivator), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethod(typeof(MyTestMVC.App_Start.UnityWebActivator), "Shutdown")]
namespace MyTestMVC.App_Start
{
    public static class UnityWebActivator
    {
        /// <summary>Integrates Unity when the application starts.</summary>
        public static void Start() 
        {
            var container = UnityConfig.GetConfiguredContainer();
            FilterProviders.Providers.Remove(FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().First());
            FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));
            DependencyResolver.SetResolver(new UnityDependencyResolver(container));
        }

        public static void Shutdown()
        {
            var container = UnityConfig.GetConfiguredContainer();
            container.Dispose();
        }
    }
}

Answer 1

container.Resolve<ICustomerService>();

Answer 2

＆＃34;如何在不启动浏览器的情况下测试操作？＆＃34;

将Moq安装到您的Unit测试项目中。

install-package Moq

然后在您的测试中创建一个ICustomerService的moq实例并存根使用的方法

var mock = new Mock<ICustomerService>();
mock.Setup(x => x.MyMethod()).Returns(true);

然后将模拟对象传递给控制器的实例，然后在控制器上调用该方法

var controller = new HomeController(mock);
var result = controller.MyMethod();

使用Moq，您可以断言是否已调用方法等
